COVID-19 Vaccine Booster Doses

A limited supply of updated (bivalent) Moderna booster vaccines is available at the CWRU Vaccine Clinic. We are currently out of Pfizer bivalent booster and will update our schedule when we receive additional supply. All COVID-19 vaccines, including the Pfizer bivalent, are available at local pharmacies such as CVS, Rite Aid and others.

Please review the CDC guidelines to see if you qualify for an updated booster and to review more information about these doses. In general, you are eligible for an updated booster if you have completed your primary series AND it has been at least two months since your last dose of vaccine (primary series or booster dose). 

Note: Per CDC guidelines, the original (monovalent) COVID vaccine can no longer be administered as a booster. 

The CWRU Vaccine Clinic is also continuing to administer primary doses of Pfizer and Moderna. At this time, the primary series must be given with the original (monovalent) vaccine formulation.

Frequently Asked Questions

Several local pharmacies and other providers are offering boosters by appointment and, in some instances, walk-in opportunities. To find locations near you, please visit Ohio’s “Get the Shot” webpage. You also can schedule appointments directly with CVS, Walgreens and Walmart

If you received your vaccination(s) in Ohio, we can provide a new card (that includes your previous vaccine doses) after you receive your booster. 

If you received your vaccine outside Ohio, please bring a photo of your vaccination card (printed or digital is acceptable). If you do not have a photo of your card, contact your state’s health department to request an official vaccination record or a new card.

When you receive a booster shot, you have the option to either get the same COVID-19 vaccine product as you received originally, or a different manufacturer’s COVID-19 vaccine. You may prefer for the vaccine type that you originally received, or you may prefer to get a different booster. CDC’s recommendations now allow for this type of mix-and-match dosing for booster shots. 

Please note: Case Western Reserve's clinic only offers Pfizer and Moderna booster doses.

Please consider the benefits and risks of each manufacturer’s vaccine. Staff at the CWRU vaccine sites cannot provide such guidance, so you may also want to discuss options with your healthcare provider before coming to your appointment. 

CWRU students may consult with University Health Services about booster vaccine options by emailing

Faculty and staff—as well as individuals coming from outside the university—should consult with their regular healthcare provider. Clinical information from the CDC about individual risks and benefits can be found on the agency’s website.

Per the CDC’s guidance, adults 18 years and older who have completed a primary series of a non-FDA authorized or approved COVID-19 vaccine are eligible to receive a bivalent booster dose of Pfizer or Moderna as long as it has been at least two months since their last dose of vaccine (including any monovalent booster).

If your first series is not a WHO-approved vaccine, those doses do not count toward vaccination in the U.S. You should start a U.S.-approved series at least 28 days after the last dose of your vaccine.
