COVID-19 Vaccine Development

The purpose of this website is to provide accurate and up-to-date information about research to develop vaccines to prevent COVID-19. The website focuses on Phase 3 studies. These studies are designed to determine if a vaccine is safe and helps prevent COVID-19. (Phase 1 and Phase 2 studies tend to be very small and are primarily used to justify moving to Phase 3. For more information about the differences between Phase 1, 2 and 3 studies, click here.)  We also include information from efforts to monitor vaccine safety AFTER the FDA has authorized a vaccine for emergency use in the United States (US).

PLEASE NOTE: We do not intend to endorse any COVID-19 vaccines or discourage their use. Our intention is simply to provide easy access to information that many people in the US might otherwise have a hard time finding. Nothing on this website should be interpreted as a medical recommendation.
