FAQs Regarding COVID-19 Vaccination

Updated:  August 27, 2021

Below is a list of frequently asked questions about the COVID-19 vaccine that have come up during Columbia University town hall discussions.


See Vaccine Documentation Upload Instructions for guidance in submitting your proof of vaccination. 


A. Vaccine Requirements (which vaccines, who, documentation, etc.) 

B. Getting Vaccinated (who, where, cost, etc.)

C. Post-vaccination (masking, social distancing, Covid testing, etc.)

D. About the Vaccines (types, how they work, efficacy, safety, etc.)

E. Especially for International Students (basic procedures about vaccination and campus access)

A. Questions About Columbia's Vaccine Requirements (which vaccines, who, documentation, etc.)

Yes, the University is currently operating seven locations that provide vaccinations to Columbia affiliates, five of which can offer vaccine to their family members, as well as to other patients, as long as they are a resident of the United States.

Morningside campus appointments at Lerner Hall (2920 Broadway) are available to students, faculty and staff, and can be made through Columbia Health. Booking an appointment can be done via the scheduling section of the Columbia Health Patient Portal. All appointments are subject to vaccine availability. Walk-in appointments may also be available.

Appointments for CUIMC students are available at CUIMC Student Health at 100 Haven Ave. CUIMC students and ColumbiaDoctors locations appointments can be made via Vaccinetogetherny.org or through your Connect account (if you use ColumbiaDoctors providers). The locations include: Black Building at 650 W 168th Street, 51 W. 51 Street, and 2702 Broadway, all in Manhattan and 26 Indian Rock Road in Suffern and 15 N Broadway in White Plains. 

All of the Columbia-operated sites will offer the specific vaccines based on availability.  Other locations throughout the tri-state area are offering the vaccine and proof of vaccination status from those locations will be accepted.

While the CDC and New York State guidance indicate that fully vaccinated individuals no longer need to wear a mask or physically distance in any setting, except in specific situations and contexts, the University continues to require that all individuals continue to wear a face covering/ mask in all indoor settings on campus as well as observe physical distancing, irrespective of vaccination status. It is important to note that individuals may choose to not wear masks or physically distance outdoors if they wish and this choice should be respected. 

See Vaccine Documentation Upload Instructions for guidance in submitting your proof of vaccination. 

COVID-19 vaccination will be mandatory for all University students, faculty, and staff—this includes officers of instruction, officers of research, officers of the libraries, student officers, officers of administration, union and non-union support staff. Full vaccination is to be completed as soon as possible.

The deadline for vaccination documentation to be uploaded was August 2. In order to accommodate late submitters, first dose evidence can now be submitted; the University will follow up to ensure completion of the second dose to ensure admission to campus in September. If you are requesting a medical or religious exemption, those also must be submitted no later than August 2, to ensure appropriate time to review and evaluate the request in advance of the September 1 deadline.

Beginning on September 2, any individual who has not submitted their vaccination documentation or has not received an approved medical or religious exemption will have a red pass on the ReopenCU app and will be unable to access campus.

See Vaccine Documentation Upload Instructions for guidance in submitting your proof of vaccination. 

High vaccine coverage is critical to preserving the health of Columbia affiliates and the broader University and surrounding community. Research continues to support the safety and efficacy of the COVID-19 vaccines authorized for use by the Federal Drug Administration (FDA) and World Health Organization (WHO) as well as their real-world effectiveness against COVID-19. Additionally, the University anticipates that one or more of the three vaccines currently authorized for emergency use in the US will received full FDA approval by the time the mandate takes effect.

We strongly recommend that all individuals, students and employees in international contexts, be vaccinated as soon as possible and receive the full dose series for optimal protection. Vaccines authorized by the FDA or by WHO will be acceptable.

Individuals who were unable to complete the required COVID-19 vaccination with FDA or WHO authorized vaccines before campus arrival will be offered a COVID-19 vaccine upon arrival. More information is available here. 

Those who have not completed vaccination or received a medical or religious exemption must request temporary authorization to access campus by completing the online form.

All such access requests must be submitted by July 23, 2021. (Reminder: The deadline to submit your vaccine documentation or medical or religious exemption request is August 2.) If the temporary authorization is granted, individuals must receive their first vaccination within three business days of arriving in New York City or within three business days after completing any mandated travel quarantine. Students with temporary authorization will be permitted to participate in orientations, move into housing, and attend classes while masking and distancing during the temporary period, outside of any required quarantine. Faculty and staff with temporary authorization will be permitted to access their assigned work areas. Individuals in the process of completing vaccination must comply with enhanced testing requirements, wear masks at all times indoors and outdoors when in or on Columbia grounds/facilities, take other appropriate precautions, and must immediately report any COVID-19 symptoms to their respective campus Medical Service (students) or their primary care provider and [email protected] (staff and faculty).

Individuals who fail to complete the University vaccine requirement within the timeline indicated will have their access to campus removed and may experience additional restrictions and repercussions.

According to the CDC, individuals who received a full series of a vaccine currently authorized for emergency use by the World Health Organization (WHO) do not need any additional doses with an FDA-authorized COVID-19 vaccine.

For individuals who were partially vaccinated with a WHO-authorized vaccine or who were vaccinated with a vaccine not authorized for emergency use by the WHO, a full series of an FDA-authorized COVID-19 vaccine can be administered with a minimal interval of 28-days post vaccination with a non-FDA-authorized vaccine.

It is Columbia’s intention to follow CDC guidance regarding individuals who may need additional vaccination in order to meet Columbia’s vaccination mandate for the Fall semester.

Individuals who have participated in a phase 3 vaccine trial in the United States will be considered fully vaccinated in the absence of formal FDA authorization if the following conditions are met: the phase 3 trial results have been published; study participants are confirmed by the study investigators to have received the complete vaccine regimen; and the sponsor has submitted for formal FDA authorization. At present, this only applies to the Novavax vaccine.

COVID-19 vaccination is mandatory for all University faculty, staff, and students.  Full vaccination is to be completed as soon as possible. Religious and medical exemptions to vaccination will be provided in accordance with New York State public health laws.

For students seeking such exemptions, please complete request forms available on the Columbia Health Immunization page (Morningside). Details for CUIMC students will be posted soon.

For employees seeking such exemptions, please complete the forms available via the ReopenCU app.

Yes. COVID-19 vaccination is mandatory for all University faculty, staff, and students.

Yes. We will accept evidence of vaccination that has received authorization by the World Health Organization.

Faculty and Staff can submit any of the following vaccine documents via the ReopenCU portal as evidence of vaccination:

  • CDC vaccine card
  • WHO booklet
  • Epic Connect record
  • Letter from a physician verifying you have been vaccinated.

See Vaccine Documentation Upload Instructions for guidance in submitting your proof of vaccination. 

Students who receive a vaccine from Columbia Health on the Morningside campus or from CUIMC's Haven on Health have their records updated automatically and do not need to upload records. Verification can be viewed at any time by accessing the Immunizations section of the Patient Portal.

Students who were vaccinated at any site other than Columbia Health on the Morningside campus must upload documentation of their vaccine in the Medical Clearances section of the Patient Portal (here are instructions). This includes students that were vaccinated at the Columbia University Irving Medical Center campus.

Acceptable proof of vaccination includes, but is not limited, to the following:

  • CDC COVID-19 Vaccine Card
  • WHO Vaccine Booklet
  • Documentation provided by a health care professional/organization/country

All documentation must be submitted in English or accompanied by a certified translation (at the employee’s or student’s expense). Verification of documentation is at the sole discretion of Columbia University. Additional information or documentation may be requested and if requested must be provided in order to verify a submission.

Yes, individuals who were unable to complete the required COVID-19 vaccination with FDA or WHO authorized vaccines before campus arrival will be offered a COVID-19 vaccine upon arrival. More information is available here. 

Those who have not completed vaccination or received a medical or religious exemption must request temporary authorization to access campus by completing the online form.

All such access requests must be submitted by July 23, 2021. (Reminder: The deadline to submit your vaccine documentation or medical or religious exemption request is August 2.) If the temporary authorization is granted, individuals must receive their first vaccination within three business days of arriving in New York City or within three business days after completing any mandated travel quarantine. Students with temporary authorization will be permitted to participate in orientations, move into housing, and attend classes while masking and distancing during the temporary period, outside of any required quarantine. Faculty and staff with temporary authorization will be permitted to access their assigned work areas. Individuals in the process of completing vaccination must comply with enhanced testing requirements, wear masks at all times indoors and outdoors when in or on Columbia grounds/facilities, take other appropriate precautions, and must immediately report any COVID-19 symptoms to their respective campus Medical Service (students) or their primary care provider and [email protected] (staff and faculty).

Individuals who fail to complete the University vaccine requirement within the timeline indicated will have their access to campus removed and may experience additional restrictions and repercussions.

No. Try to get vaccinated as soon as possible in your home country in order to protect you, your family and community from COVID-19.

We strongly urge you to get vaccinated as soon as possible, as there may be additional requirements you have to meet if you arrive on campus unvaccinated.

Domestic students, faculty, and staff, are expected to complete the vaccination requirement at least 14 days prior to their return to campus, and will be restricted from accessing campus if they have not complied with the requirement.

For international students and employees who have been unable to get vaccinated in their international location prior to their return to campus, they will be able to get vaccinated at one of the Columbia sites. They will be able to access Columbia facilities, residences, and classrooms immediately, but will be required to comply with additional precautions (such as masking and testing) until they are fully vaccinated.

Those who have not completed vaccination or received a medical or religious exemption must request temporary authorization to access campus by completing the online form.

All such access requests must be submitted by July 23, 2021. (Reminder: The deadline to submit your vaccine documentation or medical or religious exemption request is August 2.) If the temporary authorization is granted, individuals must receive their first vaccination within three business days of arriving in New York City or within three business days after completing any mandated travel quarantine. Students with temporary authorization will be permitted to participate in orientations, move into housing, and attend classes while masking and distancing during the temporary period, outside of any required quarantine. Faculty and staff with temporary authorization will be permitted to access their assigned work areas. Individuals in the process of completing vaccination must comply with enhanced testing requirements, wear masks at all times indoors and outdoors when in or on Columbia grounds/facilities, take other appropriate precautions, and must immediately report any COVID-19 symptoms to their respective campus Medical Service (students) or their primary care provider and [email protected] (staff and faculty).

Individuals who fail to complete the University vaccine requirement within the timeline indicated will have their access to campus removed and may experience additional restrictions and repercussions.

 

 

 

Columbia has a process for requesting medical or religious exemptions.

Students can submit their vaccine documentation via the Columbia Health Patient Portal (Morningside) or CUIMC Student Health on Haven portal (CUIMC).

Faculty and Staff can submit their vaccine documentation via the ReopenCU portal.

See Vaccine Documentation Upload Instructions for guidance in submitting your proof of vaccination. 

We encourage students and employees to upload their documentation as soon as possible. All affiliates are expected to complete the vaccine process at least 14 days before first accessing University facilities or participating with in-person, University-approved activities to ensure they are considered fully vaccinated at the time of first access, unless they are returning from an international location where vaccine was not available.

Students and employees may request an exemption from the vaccination requirement for specific medical or religious reasons.

Students wishing to request an exemption must submit the required request forms via the Columbia Health Patient Portal (Morningside) or CUIMC Student Health on Haven portal (CUIMC).

Employees wishing to request an exemption must submit the required request forms and documentation to [email protected]. Forms and instructions can be found on the ReopenCU app.

Students must submit their exemption request at least 30 business days before their first planned campus access. Late submissions will not be expedited. Employees are encouraged to submit their exemption requests as soon as possible.

Yes, you will be able to register for classes prior to vaccination.

You will not know who is and who is not vaccinated; however, University affiliates will not be allowed on campus unless they have met the vaccine requirement or have received a religious or medical exemption.

The U.S. Equal Employment Opportunity Commission has advised that employers may require COVID-19 vaccinations, provided that we offer exemptions to individuals with (i) disabilities that prevent COVID-19 vaccination and (ii) sincerely held religious beliefs that prevent COVID-19 vaccination. Employers may also request that an employee provide proof of receipt of a COVID-19 vaccination to ensure that employees have received the vaccine.  

The EEOC guidance takes into account the fact that COVID-19 vaccines are currently subject to Emergency Use Authorization.  Some COVID-19 vaccines may only be available to the public for the foreseeable future under Emergency Use Authorization granted by the Food and Drug Administration.  The FDA requires vaccine providers to give each individual receiving the vaccine the information contained in the Fact Sheet for Recipients and Caregivers.  Columbia complies with these obligations.  In the coming months, we expect to see vaccine manufacturers submitting requests to be considered for full FDA approval, as Pfizer has already done.  Pfizer is still awaiting full FDA approval.

The HIPAA privacy rule is not implicated in our process of asking employees to upload proof of receipt of COVID-19 vaccination. There are other laws that protect employee medical information, as well as information collected from employees as part of a medical exam or in response to a medical inquiry. Columbia will follow best practices and comply with applicable laws in maintaining privacy and security with respect to employee vaccination status.

While it is not illegal for a manager to ask employees if they are vaccinated, Columbia is establishing a policy to ensure that discussions with any follow-up questions about vaccination happen with the appropriately trained Human Resources professionals. The University has established a task force to develop guidance on best practices for these discussions and to share information about collection, privacy, and record-keeping relating to employee vaccination status.

B. Questions About Getting Vaccinated (who, where, cost, etc.)

The vaccines are currently being distributed to states in the U.S., and then from the states to various counties and municipalities. Check the New York State eligibility website for the latest information.

Eligibility for COVID-19 vaccination has expanded in New York State to 12 years of age and older.

The University is currently operating six locations that provide vaccinations to Columbia affiliates, five of which can offer vaccine to their family members, as well as to other patients.

Morningside campus appointments at Lerner Hall can be made through Columbia Health. Booking an appointment can be done via the scheduling section of the Columbia Health Patient Portal. Students at CUIMC can make appointments through the CUIMC Student Health on Haven portal (CUIMC).

All appointments are subject to vaccine availability. Walk in appointments may also be available.

CUIMC and ColumbiaDoctors locations appointments can be made via vaccinetogetherny.org or through your Connect account (if you use ColumbiaDoctors providers). The locations include: Black Building at 650 W. 168th St., 51 W. 51 St., and 2702 Broadway, all in Manhattan, and 26 Indian Rock Road in Suffern and 15 N. Broadway in White Plains.

All of the Columbia-operated sites will offer the specific vaccines based on availability. Other locations throughout the tri-state area are offering the vaccine and proof of vaccination status from those locations will be accepted.

All New York City sites currently do not require appointments. Visit COVID-19 Vaccine Finder or call one of these numbers: For New York City, dial (877) VAX- 4NYC (1-877-829-4692); for elsewhere in New York State, dial (833) NYS-4-VAX (1-833-697-4829).

Yes, as long as you are not symptomatic and have been medically cleared by a doctor after having COVID-19, you are able to get vaccinated.

Vaccination provided at Columbia University, New York Presbyterian Hospital or through ColumbiaDoctors practices will be at no cost to faculty, staff, and students.

The University complies with all New York Labor Laws, including 196-C, which provides for paid time off (PTO) to receive COVID-19 vaccine injections. Columbia’s policy concerning this PTO can be found on the University Policies website, located here.

Medical expenses will be covered by insurance. If you work for Columbia and are covered under a Columbia insurance program, those expenses will be paid under your insurance plan.

Vaccine uptake and safety monitoring is being conducted by the CDC, FDA and city and state health departments.

Vaccinated individuals receive a CDC vaccination card that includes that COVID-19 vaccine you received, the date you received it, and where you received it. Individuals vaccinated outside of the US may have been provided with different documentation.

Yes. You will be provided with information regarding the vaccine, including contraindications to receiving the vaccine, and need to provide consent prior to vaccination.

Under federal law, manufacturers and distributors of COVID 19 vaccines are entitled to immunity from suit as long as there is no willful misconduct. Under federal law, you cannot sue FDA for approving the vaccine.

The U.S. Food and Drug Administration (FDA) recently authorized a third dose of the COVID-19 vaccine for certain people who have moderate or severe immunosuppression. As a result of this authorization, the CDC is recommending a third dose of the vaccine to people who meet one or more of the criteria in the list below, and who previously received the Pfizer or Moderna COVID-19 vaccine. Please note: Currently, an additional dose is not recommended for those who are immunosuppressed and received a Johnson & Johnson COVID-19 vaccine. However, studies are ongoing and results are awaited to guide whether an additional dose of Johnson and Johnson is needed for immunosuppressed individuals.
 
Individuals in any of the following groups are recommended to receive this third dose of the vaccine:

  • On active treatment for solid tumor and hematologic malignancies
  • Recipient of solid-organ transplant and taking immunosuppressive therapy
  • Recipient of CAR-T-cell or hematopoietic stem cell transplant (within two years of transplantation or taking immunosuppression therapy)
  • Have moderate or severe primary immunodeficiency (e.g., DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Have advanced or untreated HIV infection
  • Undergoing active treatment with high-dose corticosteroids (i.e., ≥20mg prednisone or equivalent per day), alkylating agents, antimetabolites, transplant-related immunosuppressive drugs, cancer chemotherapeutic agents classified as severely immunosuppressive, tumor-necrosis (TNF) blockers, and other biologic agents that are immunosuppressive or immunomodulatory

For further information, please see COVID-19 Vaccines for Moderately to Severely Immunocompromised People | CDC). At this time, there is no need or recommendation for patients who do not meet any of the criteria above to receive a third dose.

Those individuals who qualify should be administered the same Pfizer or Moderna shot they received previously. If your original mRNA vaccine is not available, the CDC allows for patients to receive the other product.
 
If you qualify for a third dose of vaccine, please call your provider treating you for the immunosuppressed condition(s) noted above. In addition, there are multiple locations available in New York City and New York State where you can receive your third dose of vaccine; the following sites can help you find community-based locations: vaccinefinder.nyc.gov and covid19vaccine.health.ny.gov. The Lerner Hall testing site will not be administering these third doses at this time.

C. Questions About Post-Vaccination (masking, social distancing, Covid testing, etc.)

While the CDC and New York State guidance indicate that fully vaccinated individuals no longer need to wear a mask or physically distance in any setting, except in specific situations and contexts, the University continues to require that all individuals continue to wear a face covering/ mask in all indoor settings on campus as well as observe physical distancing, irrespective of vaccination status. It is important to note that individuals may choose to not wear masks or physically distance outdoors if they wish and this choice should be respected.

Yes. At present, all individuals including those vaccinated, will need to continue to participate in the University testing program (e.g. gateway, sampling, mandatory testing).

Yes, all individuals, including those vaccinated, must participate in the Required University Protocols for coming to campus. Face coverings, along with other safety measures, will still be required.


1. Read and Sign the Health Compact
2. Take Safety Training
3. Self-quarantine, if required
4. Get Tested as per Columbia testing program
5. Complete the Daily Symptom Self-check

In general, a person is considered protected 2 weeks after their second dose in a 2-dose series and 2 weeks after a single-dose vaccine. This allows the body to build up immunity to the disease. However, it is not necessary for one to quarantine between each dose. Individuals are recommended to continue with their daily lives while following COVID-19 public health recommendations.

Asymptomatic individuals who have been vaccinated are not required to quarantine after exposure to a person with COVID-19, if the following criteria are met:

  • Fully vaccinated (defined as being 2 or more weeks after the final dose (e.g., first for Janssen/Johnson & Johnson, second for Pfizer and Moderna) of the vaccine approved by the FDA or authorized by the FDA for emergency use. Vaccines that are not authorized by the U.S. Federal Drug Administration (FDA) for emergency use or approved by the FDA do not satisfy this definition).
  • While not required to quarantine, vaccinated individuals must still:
    • Monitor for symptoms for 14 days.
    • Follow all other guidance including face coverings, hand washing, and social distancing.
    • Immediately self-isolate if any symptoms develop and report the symptoms to [email protected].

D. Questions About the Vaccines (types, how they work, efficacy, safety, etc.)

There are currently three vaccines that have received Emergency Use Authorization by the U.S. Federal Drug Administration. These include the Pfizer BioNTech vaccine, the Moderna vaccine, and the Johnson & Johnson's Janssen vaccine.* 

The Pfizer and Moderna vaccines use genetic material known as messenger RNA (often abbreviated as mRNA) that cells use to make proteins. When the vaccines are injected into the body, the mRNA which codes for the coronavirus spike protein, enters human cells and instructs the cells produce a protein that mimics the spike proteins found on the surface of the coronavirus. These vaccine-induced proteins then stimulate the immune system to produce antibodies to fight the virus. Once produced, if a person is exposed to SARS-CoV-2, the antibodies latch onto the coronavirus spike protein and prevent the invading virus from entering your cells and making you sick.

The Johnson & Johnson vaccine uses a different approach to deliver the gene encoding the coronavirus spike protein. This is the viral vector approach. In this instance, a harmless cold virus, adenovirus type 26, is modified in the laboratory in two essential ways: (1) some of the Ad26 DNA is removed which renders the Ad26 non-replicative (i.e., it cannot grow or multiply in your body); and (2) DNA coding for the coronavirus spike protein is inserted into the Ad26 vector.  Once injected, the spike protein is produced and an immune response to it is generated. The resultant antibodies to the spike protein act in a similar fashion to those produced in response to mRNA vaccines and prevent the entry of the invading virus into your cells.

Pfizer and Moderna require two doses, given three (Pfizer) to four (Moderna) weeks apart. Johnson & Johnson requires one dose.

No. None of the COVID-19 vaccines contain live SARS-CoV-2 virus.

All current COVID-19 vaccines in use in the US have been shown to be effective based on criteria from the US Food and Drug Administration (FDA). Findings from the Pfizer and Moderna vaccine studies showed that these vaccines were more than 90% effective in preventing symptomatic COVID-19. Findings from the Johnson and Johnson vaccine study showed that the vaccine was 72% effective in United States. It should be noted that comparison of efficacy across these vaccines can be misleading as the studies were conducted at different timepoints and in differing epidemic contexts. Real world data show that these vaccines are even more effective at preventing serious COVID-19 illness and hospitalizations.  

All three vaccines have been shown to have favorable safety profiles with the most commonly reported side effects being mild to moderate.

There have been reports of a rare type of adverse event following the use of the Johnson and Johnson vaccine that suggest an increased risk of a condition called thrombosis (blood clotting) with thrombocytopenia syndrome (TTS) (low blood platelets). This adverse event is very rare, occurring at a rate of about 7 per 1 million vaccinations, and has been reported more commonly in women between 18 and 49 years old. A thorough review by the CDC Advisory Committee on Immunization Practices (ACIP) of all available data shows that the vaccine’s known and potential benefits outweigh its known and potential risks.

In considering the risks and benefits of the vaccines, individuals should consider the risks of COVID-19 disease and its complications while weighing the protective effects of the vaccines and their social and interpersonal benefits.

Vaccine safety data are being monitored in order to determine longer term safety profiles.

The most common sides events reported have been mild to moderate. These side effects include pain or swelling at the injection site, fatigue, chills, muscle aches, and headaches. Most of these side effects resolve promptly.

Rare severe allergic reactions (e.g., anaphylaxis) after the Moderna and Pfizer vaccines and cases of blood clotting with low platelets after the Johnson and Johnson vaccine have been reported. However, these have been shown to be extremely rare and the associated risk has been shown to be much lower than the risk of getting COVID-19.

On April 23, 2021, the CDC Advisory Committee on Immunization Practices recommended the use of the Johnson and Johnson vaccine be resumed in adults 18 years and older under the FDA’s Emergency Use Authorization. In addition, the Committee recommended that a warning about the rare, but potentially dangerous blood clotting disorder be added to the label of the vaccine. This is to promote awareness, particularly among women aged 49 and younger, of the rare but increased risk of the blood clotting event and that there are other COVID-19 vaccine options available for which this risk has not been seen.

The risk has been observed to be the highest in women aged 18-49. Therefore, if you fall within this category and receive the Johnson and Johnson vaccine, it is recommended that you be cognizant of the possible symptoms associated with this rare adverse event for 2-3 weeks after vaccination. These include severe or persistent headaches or blurred vision, shortness of breath, chest pain, leg swelling, persistent abdominal pain, easy bruising or tiny blood spots under the skin beyond the injection site. The complete CDC recommendation for use can be found here.

No, receiving the vaccine can in no way cause COVID-19.

All three of the vaccines currently in use in the US have been shown to substantially reduce spread of the virus.

Yes, the trials included groups who are at high risk for COVID-19, including those who are 65 years and older, have underlying medical conditions (such as diabetes, high blood pressure, obesity), among others. 

The duration of protection from COVID-19 provided by these three vaccines is not known as of yet. However, the ongoing monitoring of the clinical trial participants has shown that protective effects of the vaccine are still evident 6 months after vaccination. Researchers will continue to monitor study participants to determine the duration of protection.  

Pfizer and Moderna vaccines require two doses to be effective. The second dose of the Pfizer vaccine is administered three weeks after the first dose while the second dose of the Moderna vaccine is administered four weeks after the first.

Johnson & Johnson requires one single dose.

The Pfizer and Moderna vaccine studies found that two doses were needed to optimize the immune response and provide the best possible protection from COVID-19. Therefore, the 2-dose series is strongly recommended and will be necessary for documentation of full vaccination.

No, the CDC recommends against this approach. This was not evaluated and there is no evidence that the vaccines are interchangeable. If you get a first dose of one vaccine, you should get a second dose of the same vaccine. Individuals administering the vaccine will be tracking this issue.

According to CDC guidance, second doses administered within a grace period of 4 days from the recommended date for the second dose are considered valid; however, doses administered earlier do not need to be repeated. The second dose should be administered as close to the recommended interval as possible. However, there is no maximum interval between the first and second dose for either vaccine.

Currently, the safety of any vaccine combination has not been determined and therefore the CDC advises against the mixing of COVID-19 vaccines. Research regarding the potential need for a booster injection of a COVID-19 or routine vaccination is underway.

COVID-19 vaccines were previously recommended to be administered alone, with a minimum interval of 14 days before or after administration of any other vaccines. This was out of an abundance of caution and not due to any known safety or immunogenicity concerns. However, substantial data have now been collected regarding the safety of COVID-19 vaccines currently authorized by FDA for use under EUA. COVID-19 vaccines and other vaccines may now be administered without regard to timing. This includes simultaneous administration of COVID-19 vaccine and other vaccines on the same day, as well as co-administration within 14 days.

Preliminary evidence suggests that the vaccines authorized for use in the US provide good coverage for the virus variants identified thus far in the country.

Yes, as per CDC recommendations, vaccination should be offered to persons regardless of history of prior symptomatic or asymptomatic coronavirus infection, including a positive antibody test. For persons who experience lingering symptoms for weeks and months after diagnosis (i.e., “COVID-19 long-haulers”), vaccination is similarly considered safe and likely efficacious.

For persons with current COVID-19, vaccination should be deferred until recovery from acute illness.

 

Per CDC and FDA recommendations, those who have had a severe allergic reaction (e.g., anaphylaxis) to any component of the vaccines should not be vaccinated. For those who have had a severe allergic reaction to another vaccine or injectable treatment (intramuscular, intravenous, or subcutaneous) the vaccine can still be administered; however, it is recommended that the risks be discussed with a healthcare provider and that the recipient be monitored for 30 minutes post-vaccination. For those with any other allergy (e.g. food, pollen, pets), vaccination should be offered. All individuals who received vaccines should be observed for about 15 minutes after vaccination.

The Pfizer and Moderna vaccines are very similar in composition. They consist of the mRNA particle, water, lipids, salt, sugar, and FDA-approved buffers. A complete list of the ingredients can be found here for Pfizer (page 2) and here for Moderna (page 2). The ingredients of the Johnson and Johnson vaccine can be found here (page 2).

None of the vaccines in use in the US contain live virus.

Currently, there are no data on the safety or efficacy of COVID-19 vaccination in persons who received monoclonal antibodies or convalescent plasma for prevention or treatment of COVID-19. Therefore, it is recommended that vaccination be deferred for at least 90 days after receiving such interventions to avoid interference with vaccine-induced immune responses.

Persons who have been identified recently as a close contact of someone with COVID-19 should defer vaccination until quarantine period has ended to avoid exposing healthcare personnel or other persons during vaccination visit.

Studies of the Moderna and Pfizer vaccines have resulted in reassuring safety results for pregnant or breastfeeding women. A discussion with a healthcare provider can help inform this decision.

Additionally, there is no recommendation for routine pregnancy testing before receipt of a COVID-19 vaccine. Those who are trying to become pregnant do not need to avoid pregnancy after COVID-19 vaccination. Again, a consultation with a healthcare provider is recommended in making this decision.

According to CDC recommendations, the vaccine may be administered to persons with underlying medical conditions who have no contraindications to vaccination. This guidance is based on the studies that have demonstrated similar safety and efficacy profiles in persons with underlying medical conditions compared to those without such conditions.

For those who are immunocompromised, safety and efficacy of vaccine has yet to be determined given the limited data for these groups. However, immunocompromised persons may still receive COVID-19 vaccines, with counseling, unless otherwise contraindicated given increased risk for COVID-19.

 

At this point in time, children under 12 years of age are not considered a priority group for early phases of vaccination given their low risk for severe disease.

Note that children who are 12 years of age or older, should only receive the Pfizer vaccine at this stage. 

Under federal law, manufacturers and distributors of COVID 19 vaccines are entitled to immunity as long as there is no willful misconduct.

E. Especially for International Students

Acceptable proof of vaccination includes, but is not limited to:

  • A Centers for Disease Control (CDC) COVID-19 vaccine card.
  • World Health Organization (WHO) vaccine booklet.
  • Documentation provided by a health care professional/organization/country.

All documentation must be submitted in English or accompanied by a certified translation at your own expense. Learn more about documentation here.

  • There are services across the globe that provide translation services. To be certified it needs to carry a statement that reflects it is a certification of (name the record) and carries the name of the person and organization performing the translation. Most services will sign or stamp the translation as well to demonstrate authenticity. 
  • Please note: The University does not recommend any particular agency for these services.

Columbia makes every effort to ensure the privacy of all health-related information. More details on our privacy policy can be found online.

No, if you got your vaccine on at Columbia, you do not need to upload the documentation. Students who receive a vaccine from Columbia Health on the Morningside campus or from CUIMC's Haven on Health have their records updated automatically and do not need to upload records. Verification can be viewed at any time by accessing the Immunizations section of the Patient Portal.

No, international students will be able to receive their vaccine once they arrive on campus. They should plan to get it shortly after arrival. Students will have access to campus following quarantine and testing requirements while they get their vaccine, but they will have additional restrictions in place until fully vaccinated (i.e. travel quarantine, face coverings, testing, and physical distancing).

WHO continues to review and approve vaccines. International students should upload their vaccine cards even if it is not yet WHO approved (using the COVID-19-unspec non-US admin option in the medical clearances area of the portal). If the vaccine is approved before their arrival, they will not need to be revaccinated. If not, they will need revaccination when they arrive. The CDC recommends that individuals wait a minimum of 28 days after the last dose of their non-FDA or WHO-authorized vaccine prior to receiving an FDA-authorized vaccine.

Students who are not fully vaccinated with an FDA or WHO approved vaccine must quarantine for 7-days after arriving in the US from international travel. This will also include a test at day 3-5 after return. They will not be able to attend class or other events until the quarantine is completed and results of the gateway test on day 3-5 are received.

  • Once quarantine and testing requirements are completed, students will be able to participate fully on campus, but additional requirements will be expected until they are fully vaccinated (two weeks after your final dose), including wearing a face covering, physical distancing, and testing.

Students who are fully vaccinated with an FDA or WHO approved vaccine are required to test on day 3-5 after return but are not required to quarantine. They are required to get a gateway test but are able to attend class and other events.

Students who have completed their quarantine and testing will be able to participate in University activities while they get their vaccine, but will have additional requirements until they are fully vaccinated (two weeks after the final dose), including wearing a face covering, physical distancing, and testing.

Students wishing to request a medical or religious exemption must submit the required request forms and supplemental documentation via the Immunization Records section on the Columbia Health Patient Portal (Morningside) or Student Health on Haven portal (CUIMC).

In addition to uploading the vaccination documentation, they will need to:

  • Complete gateway testing by September 9 if they are accessing campus for the first time after January 4, 2021.
  • Sign the updated Compact on the Reopen CU app by August 16 (even if they signed it previously).
  • Complete the COVID-19 safety training if they did not complete one last academic year.
  • Attest daily that they are not experiencing COVID-19 symptoms.

What do I need to do to return to campus if I was feeling unwell (not with COVID)?

  • Anyone with symptoms should consider staying home until symptoms have resolved
  • Anyone with respiratory symptoms should wear a mask while symptomatic and for 48 hours after resolution of symptoms
  • If symptoms do not resolve or worsen, or if there is an exposure history to COVID-19, recommend getting COVID tested prior to return to campus
  • Students can reach out to their campus Medical Service for guidance

If I am out sick (not with COVID), do I need to get a negative test to be able to come back to in-person instruction?

  • No. We do not expect students to get a “sick note” each time they miss class. After September 9, return protocol after symptoms is the same regardless of vaccination status. See information in previous FAQ.

Accommodations will vary by program. Some schools/programs will provide remote access for up to 30 days to allow for a late arrival by international students who are delayed due to circumstances beyond their control. Students should check with their respective programs.

  • In addition to your COVID-19 vaccine, all students are required to have received their MMR and meningitis vaccine prior to registration, as well as get the influenza vaccine in the fall.
  • New York State public health law and University policy require that students must also document that they either have received the meningococcus meningitis vaccine or have declined to receive it.
