Nasal spray COVID-19 booster shot study
Treatments studied
Part of Infections, Lungs & breathing clinical trials.
This trial tests a nasal spray booster for people who have already had 2-3 doses of COVID-19 inactivated vaccine. It studies if the spray is safe and boosts your immune system. You can join if you are healthy, have not had COVID-19 in the last 3 months, and had your last vaccine dose more than 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 a new nasal spray booster for COVID-19 in adults 18–64 who have already had a primary vaccine series and at least one booster. The goal is to see if it is safe and triggers a good immune response.
This Phase 3 trial tests whether a medicated nasal spray can stop COVID-19 from starting after you’ve been exposed to someone who recently tested positive. You must start very soon after the person became symptomatic, and you’ll be checked for eligibility based on timing and your health history.
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 Phase 3 trial tests a booster vaccine made from a three-part COVID-19 protein (aimed at XBB, BA.5, and Delta) to see how well it works and is tolerated. It may help adults who are due for a COVID-19 booster, including people with certain health conditions, depending on screening results.
This Phase 2 study tests a booster vaccine made from a COVID-19 protein (XBB + prototype) to help your immune system respond better. You may be able to join if you’re an adult who is due for a booster and meets health and safety screening checks.
