COVID-19 vaccines may reduce transmission, experts say, but vaccinated Americans still need to wear masks in public. Here's why.

When COVID-19 vaccinations began, U.S. health officials encouraged vaccinated Americans to continue wearing masks in public because scientists were still unsure if they could carry the virus that causes the disease after being inoculated. 

Recent results from real-world studies show theCOVID-19vaccines protect against asymptomatic infection, suggesting they also drastically reduce virus transmission. 

But health experts still recommend wearing masks in public, regardless of vaccination status, as more research is needed to confirm whether vaccinated people can spread the virus, and asvariants become more prevalent in the U.S. and states see cases spikes.
