New COVID-19 vaccine study for those with prior mRNA vaccines
Part of Infections, Lungs & breathing clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 64 years old.
- You have had at least two doses of the Pfizer or Moderna COVID-19 vaccine, with your last dose more than 4 months ago.
- You test negative for COVID-19 at the screening visit.

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 trial tests a new nasal spray COVID-19 booster vaccine. It aims to see if the vaccine is safe and produces a strong immune response when given through the nose and inhaled, in people who have already been vaccinated.
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.
This study tests a new antibody medicine for people with COVID-19 who are at high risk of getting very sick. If you qualify, you would receive the study drug or a placebo (inactive substance) to see if it helps you recover without needing to go to the hospital.
This study tests a new mRNA vaccine (called mRNA-1283) to protect against COVID-19 in children from 6 months to under 12 years old. It aims to see if the vaccine is safe and produces a good immune response.
This trial tests updated COVID-19 vaccines designed to better protect against current variants. It's for people who have already been vaccinated and are at higher risk for severe COVID-19.
