First seen Apr 19, 2026 · Last updated May 21, 2026 · Updated 4 times
Summary
This early-stage trial tests a new booster vaccine called OCU500 for COVID-19. Unlike a shot, this vaccine is given as a nasal spray or inhaled mist. The study involves 80 healthy adults aged 18-64 who have already had their primary COVID-19 vaccines and at least one booster. The main goal is to check if the vaccine is safe and to see how well it triggers an immune response.
