Coronavirus infections are on the rise again in the United States. CNN Medical Analyst Dr. Leana Wen explains how the dominant Delta variant impacts those who have been vaccinated and what precautions they should take.
While more than 99% of deaths are among those unvaccinated, anecdotal reports abound of breakthrough infections, or cases of fully vaccinated people who still test positive for Covid-19 — including several New York Yankee baseball players.
CNN: Can vaccinated people become infected with Covid-19?
That means breakthrough infections — or infections in people who are fully vaccinated — can and do happen.
The vaccine protects you well, but if you are constantly exposed to people who are carrying coronavirus, at some point you could have a breakthrough infection.
CNN: Do we know how common breakthrough infections are or whether people who are vaccinated but get infected are able to transmit to others?
That calls into question what happens if someone is vaccinated but infected with the Delta variant.
We just don't know, at this point, how likely it is for a vaccinated person with a breakthrough infection due to the Delta variant to be contagious to others.
CNN: Do the unknowns around the Delta variant change your recommendations for vaccinated people interacting with others?
On the other hand, a vaccinated person who is exposed constantly to unvaccinated people, in crowded, indoor settings where no one is wearing masks, could become infected themselves.
