The delta variant is more contagious than its predecessors, but COVID-19 vaccines still provide strong protection against itWhat should I know about the delta variant? It's the most contagious coronavirus mutant so far in the pandemic, but COVID-19 vaccines still provide strong protection against it. The change is based on recent research suggesting that vaccinated people who get infected with the delta variant can spread it to others, even if the vaccinated don’t get seriously ill. Some breakthrough cases with mild or no symptoms were always expected, since the vaccines were designed to prevent serious illness. It’s not yet clear if the delta variant makes people sicker.
