Experts: The Covid-19 vaccine does not eliminate wearing a mask ... for this reason

People who will receive the Corona vaccine, to prevent “Covid-19” disease, may have to wear a mask because the vaccine will prevent infection with Covid-19, but it is not clear until now whether it will prevent the spread of the virus to others, according to what was stated in the Sky website News ".

The reason is that the trials of the two companies Moderna and Pfizer only monitored whether the people who were vaccinated had contracted corona or not, but did not notice whether they had spread the virus without showing symptoms on them.

Marion Bieber, an immunologist at the University of Washington in Seattle, explained: "It is a race ... indeed, Corona vaccines have proven to be strong shields against severe symptoms and repercussions, but this does not guarantee their effectiveness in the nose and throat and whether they are able to limit the spread of the virus."

However, experts stress that they are optimistic that vaccines will eliminate the virus enough even in the nose and throat to prevent immunized people from spreading it to others.

And some studies had indicated that even people who did not show symptoms of Corona "could have large amounts of virus particles in their noses."
