Why You Might Still Need a Mask Post-Vaccination

The Covid-19 vaccines under review look very promising, but one thing that hasn’t been confirmed yet is whether the vaccines will not only prevent people from getting sick but also prevent people from passing the virus on to others.

As Apoorva Mandavilli reports in the New York Times this week, “the Pfizer and Moderna trials tracked only how many vaccinated people became sick with Covid-19. That leaves open the possibility that some vaccinated people get infected without developing symptoms and could then silently transmit the virus — especially if they come in close contact with others or stop wearing masks.” This might mean that people will be asked to continue to wear masks until that is determined.

Thankfully, scientists do plan to study this, and there should be a clearer answer as time goes on and more people are vaccinated. Read more about the issue below.
