Frequently Asked Questions about COVID Boosters

I was initially vaccinated with a WHO approved vaccine outside of the US. Which booster can I receive?

If it has been 5 months since you were vaccinated with all the recommended doses of a WHO authorized vaccine, you can get a single booster shot of Pfizer or Moderna COVID-19 vaccine.  For more information, click here.  The UHC has appointments available for the Pfizer vaccine.

It has been less than 5 months since I completed my last dose of COVID vaccine abroad. What should I do?

If you received a dose of a WHO authorized vaccine outside of the US, you will need to wait to receive your first booster until you are eligible, which is 5 months after completing the initial COVID vaccine series.  

Once I am eligible for a booster, how can I schedule an appointment for a vaccine?

A limited number of appointments for the Moderna Bivalent Booster are available at the UHC.  Please visit to schedule an appointment. If you do not see any appointments available, check back often.  We recommend that you schedule as soon as you become eligible.  

Is there any cost for the vaccine?

The COVID vaccine is free, and there is no cost to you.  If you have health insurance, please bring your insurance card with you to your vaccine appointment, as we do process your visit through insurance.
