This study is evaluating the safety of the Pfizer & BioNTech COVID-19 vaccine when given as a 3rd or 4th dose to 18 to 30 year-olds who have received 2 or 3 prior doses. All participants will receive the COVID-19 vaccine booster during their time in the trial.
An Important Contribution
The development and approval of an effective COVID-19 vaccine was an important milestone in our fight against COVID-19. We are grateful to all who have made the choice to protect themselves and others by receiving the COVID-19 vaccine. As the pandemic continues, it's important to learn more about the safety of the COVID-19 vaccine when given as a 3rd or 4th dose to adults who have received 2 or 3 prior doses.
By choosing to volunteer, you will represent others like you - in age, gender, race, ethnicity, and from communities like yours. Involving people from all backgrounds will help ensure the booster is safe for everyone.
Joining a clinical trial is an important decision for you and your family. Thank you for considering this study.
