COVID-19 Booster Vaccine Study for Previously Vaccinated Adults
This study tests new COVID-19 booster vaccine candidates in healthy adults who previously received mRNA COVID-19 vaccines. Researchers will monitor safety and how well your immune system responds to help develop better COVID-19 protection.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18–65 years old
- You received at least 2 doses of mRNA COVID-19 vaccine (Pfizer or Moderna) more than 6 months ago
- You are in generally good health or have a stable medical condition that hasn't recently worsened
- You test negative for active COVID-19 at screening and before vaccination
- You have normal blood counts and organ function based on blood and urine tests
- Women of childbearing potential must use effective birth control for 4 months after vaccination; men must use contraception and not donate sperm during this time

Other trials that look related to this one.
This trial tests a new type of COVID-19 booster vaccine that targets a protein to help your immune system. It's for people who already had a primary vaccine series and at least one mRNA booster, with the last booster at least 6 months ago.
This study tests a booster vaccine for HIV in people who were part of an earlier HIV vaccine trial. The goal is to see if it's safe and helps the immune system fight HIV better.
This trial tests a next-generation COVID-19 vaccine given as an inhaled mist. It is for adults who have already had at least 3 doses of an mRNA COVID vaccine and are looking for a potentially stronger or longer-lasting immune response.
This study tests a new booster vaccine against COVID-19 that uses mRNA technology, similar to the Pfizer or Moderna shots. If you've already had your primary series and a booster, this could help keep your immunity strong.
This study tests a new type of COVID-19 vaccine that is designed to train your immune system to make stronger, longer-lasting protection. You may be able to join if you are 40–64, have already had at least two doses of a mRNA COVID-19 vaccine (Pfizer or Moderna) more than 4 months ago, and are generally healthy.
This trial tests an updated COVID-19 booster vaccine designed to improve protection for people who are older or have health conditions that increase their risk of severe COVID-19. If you qualify, you would receive one dose of the study vaccine and be monitored for safety and immune response.
