“The U.K. government said it is preparing to deliver booster Covid-19 vaccine shots from September, in case extra protection is needed to deal with waning immunity from initial doses and to bolster protection against new variants of the coronavirus.” Will certainly happen in the U.S. as well. Since all the talk about variants of “the virus,” I have seen people at stores wearing two masks again. They will be first in line to get their third shot and then will still probably wear their masks.
