The Pfizer & BioNTech COVID-19 Vaccine Studies

The Studies

We are proud to be part of developing the world's first COVID-19 vaccine, which has protected millions globally from this devastating disease. But our work is not done. Fighting COVID-19 requires adjustments to the vaccine to address new variants and provide ongoing protection. We also believe combining the COVID-19 vaccine with vaccines for flu and RSV will make it easier for people to protect themselves from these common and severe respiratory viruses.

With your help, we can advance development of the next generation of COVID-19 vaccines. Learn more about our COVID-19 vaccine studies currently enrolling.

Participation Matters

We are profoundly grateful to the people who volunteer for our clinical trials. By choosing to volunteer, you are helping to advance potential investigational vaccines for people around the world.

Factors such as genetics, race, ethnicity, gender, and age, can affect a person's risk factors for severe infectious diseases and how they respond to a vaccine. In the U.S., African Americans, Alaskan Natives, American Indians, Latino people, and adults over the age of 65 are more significantly impacted by severe illness and hospitalizations from COVID-19, flu, and RSV than other groups. 1, 2, 3, 4 That is why it is so important that clinical trials include people of all backgrounds. Everyone needs to be represented.

Each and every person who volunteers for a clinical trial plays a powerful role. Joining a clinical trial is an important and personal decision. We hope it is one you will consider.
