Revaccination for International Affiliates

Only COVID vaccines that are FDA-approved/-authorized, with demonstrated effectiveness against known variants, will be accepted. Those include the Pfizer-BioNTech, Moderna, and J&J/Janssen vaccines.

Individuals who work or study in the School of Medicine who have not received one of these vaccines must be revaccinated with a full course of one of these vaccines upon arrival—that is two doses, properly spaced, of Pfizer-BioNTech or Moderna, and one of J&J/Janssen. Individuals who are not in the school of medicine are not required to be revaccinated. 

Only mRNA boosters (Pfizer/Moderna) will be accepted. If you already received a J&J booster, you may wait six months to get the mRNA booster. If you were vaccinated with a non-FDA-approved vaccine (e.g., Sinopharm, Sinovac, etc.), you are immediately eligible for a booster (you may wait 28 days following your last dose). Only one booster dose (either Pfizer or Moderna) is required for those individuals.

How to get revaccinated

Anyone needing to get revaccinated should schedule an appointment to receive one of the three authorized vaccines as soon as possible. More information on vaccine clinics is available at this link. You can also get vaccinated at any local pharmacy or through Johns Hopkins Medicine by calling 443-997-1875 or through MyChart. For those who need to get a second dose only, these can be obtained at JHU-sponsored clinics (not through MyChart or Johns Hopkins Medicine).

Once you have been fully vaccinated, you should log back into the Vaccination Management System (VMS) and upload your new vaccination documentation.

Required testing

Until you are fully vaccinated (two weeks after your final dose), you are expected to follow the same masking and testing requirements (twice weekly) as those with vaccination exceptions and to wear a mask (even if the JHU-wide mask mandate is no longer in effect). You must complete your vaccinations and upload documentation to the Vaccine Management System as soon as possible after your final dose.  

The university has established several campus locations across JHU for mandatory or voluntary testing. Detailed testing site information and hours of operation can be found on the Testing Locations + Schedules page on this website. 

Testing appointments can be made through MyChart (also available as a mobile app from the Apple App Store or Google Play). You must have an active MyChart account to participate in the testing and vaccination programs at JHU. If you are having issues activating your MyChart, call 888-676-3433 or email Testinginfo@jhu.edu.

Is it safe to be revaccinated if I previously received a non-FDA-approved vaccine?

While there are as yet no controlled studies on revaccination, Johns Hopkins vaccine, medical, and public health experts do not believe there is a risk to “double” or “cross-platform” vaccination, and do see potentially significant benefits for individuals and for public health within our community more broadly. Indeed, double vaccination is not that much different than boosters or vaccination postCOVID, which is done frequently without adverse effects.

How long do I have to complete revaccination? Am I allowed to wait some amount of time if I just got vaccinated with an international vaccine?

JHU affiliates who do not work or study in the School of Medicine are not required to be revaccinated. If you were vaccinated with a non-FDA-approved vaccine (e.g., Sinopharm, Sinovac, etc.), you are immediately eligible for a booster (you may wait 28 days following your last dose). Only one booster dose (either Pfizer or Moderna) is required for those individuals.

If you work or study in the School of Medicine, you must be revaccinated as soon as possible (you may wait up to 28 days after your most recent international vaccination to begin the required revaccination process). Until you are fully vaccinated (two weeks after your final dose), you are required to test twice weekly. While you are permitted to be vaccinated at any U.S. pharmacy or other vaccination location, it may be easiest to get revaccinated through Johns Hopkins University or Johns Hopkins Medicine. More information on how to get revaccinated is available on the Revaccination for International Affiliates page of this website.

If I am in the process of getting vaccinated/revaccinated, do I need to let anyone know?

No, but you need to submit proof of being revaccinated once you are done receiving the FDA-authorized vaccines. Once you complete your vaccinations, please upload to the Vaccine Management System.

Until you are fully vaccinated (two weeks after your final dose), you are required to test twice weekly and to wear a mask (even if the current JHU-wide mask policy changes and vaccinated affiliates are no longer required to wear a mask).

What should I do if I only need a second dose, because I received a first dose of an FDA-authorized vaccine while living abroad?

For those who may have received a first dose of an FDA-authorized vaccine abroad and only need to receive a second dose of an FDA-authorized vaccine, please be sure to bring any paperwork you have that shows the vaccination information and date of vaccination. After you are vaccinated, you must upload proof of both vaccines in one submission. (The Vaccine Management System allows submission of multiple documents, so please submit any proof of vaccine and English translations for documents in languages other than English.) 

While you are permitted to be vaccinated at any U.S. pharmacy or other vaccination location, it may be easiest to get revaccinated through Johns Hopkins University or Johns Hopkins Medicine. More information on how to get revaccinated is available on this website.

Note: Second doses can be obtained at JHU-sponsored clinics.

Can I receive only one dose of an FDA vaccine as a booster if I have already been vaccinated with a non-FDA vaccine?

Yes, individuals who work or study outside of the School of Medicine may receive one booster dose of an mRNA vaccine (Pfizer or Moderna).

If you work or study in the School of Medicine, you must follow Johns Hopkins Health System guidance and are required to be revaccinated with an FDA-approved vaccine (Pfizer, Moderna, or J&J).
