COVID-19 Vaccine

Man receiving COVID vaccine

The COVID-19 vaccines are among the most effective and safest vaccines ever developed. Both the Pfizer and Moderna vaccines are shown to be approximately 95% effective. Although the original authorizations were for a two-dose regimen, the CDC has expanded that to three doses for patients who are moderately to severely immunocompromised. In addition, the CDC also recommends a booster dose six months after the last dose of vaccine. It is safe for most patients to receive the vaccine. It is also considered safe to receive the flu vaccine around the same time as a COVID-19 third dose or booster dose. Talk to your physician if you have questions.

For some patients in active treatment that causes immunosuppression, the vaccine may not be effective. Talk to your oncologist or primary care physician.

How to get the vaccine: Visit  or to find a COVID-19 vaccination location near you, then schedule your appointment directly with the location you choose. Moffitt is no longer offering vaccine clinics.

It is also important not to delay any treatment for cancer in order to receive the COVID-19 vaccine.

If you are a cancer survivor, it should be safe for you to receive the vaccine. If you have concerns, you should talk to your oncologist or primary care physician.
