New Data on COVID-19 Transmission by Vaccinated Individuals A Q&A WITH AMESH ADALJA | APRIL 8, 2021

Can we say with any degree of certainty that vaccinated people are unlikely to spread COVID to unvaccinated individuals?The emerging data confirms what many of us thought would be the case—that not only do the vaccines stop symptomatic COVID, but they also make it highly unlikely that someone can even be infected at all.
I think the preponderance of the evidence supports the fact that vaccinated individuals are not able to spread the virus.
