Health officials involved in coronavirus vaccine clinical trials said that the drugs weren't designed to stop the spread of COVID-19. The goal was to prevent severe COVID-19 cases and deaths. Preventing infection would be a welcome side effect. That meant vaccinated individuals could potentially still get infected, and they could still infect others, even though they might not experience the illness themselves. When the first results rolled out, we learned the vaccine candidates were highly effective at reducing the risk of severe disease and preventing deaths. The studies were not able to prove that the vaccine could prevent infection.
Nearly three months later, on the anniversary of the coronavirus pandemic, Pfizer and BioNTech released the conclusions of a new study that says their mRNA drug is actually highly effective at preventing COVID-19 transmission.
