Study Details

Study Description

Brief Summary

The purpose of this clinical trial is to learn about the safety, tolerability and immunogenicity of a BNT162b, RNA-based SARS-CoV-2 vaccine candidate given as a booster dose in adults to prevent COVID-19.

This study is seeking participants who are:
  • 18 through 55 years of age and healthy (who may have preexisting disease if it is stable);

  • have received 1 booster dose of a US-authorized COVID-19 vaccine, with the last dose being 90 or more days before the first visit of this study.

All participants in this study will receive 1 of the 2 study vaccines: BNT162b5 Bivalent or BNT162b2 Bivalent. Both vaccines are investigational but are very similar to BNT162b2 (Comirnaty), a COVID-19 RNA vaccine approved for use in the US and in many countries.

All participants will receive a single 30 microgram dose of the study vaccine at the first study clinic and will return to the study clinic 4 more times. At each clinic visit, a blood sample will be taken. They study is about 6 months long for each participant.
