Phase 3 Adolescent Study for SARS-CoV-2 rS Variant Vaccines
Completed
This study is a large-scale investigation (Phase 3) into a new booster shot designed specifically for teenagers. The booster targets a particular variant of COVID-19, Omicron XBB.1.5. The main focus is on safety: researchers want to see if this new booster is safe for teenagers who have already received two doses of the Pfizer or Moderna mRNA COVID-19 vaccines. To ensure a fair comparison, the study will use a double-blind approach. This means two groups of teenagers will receive booster shots,... Read More
