Doctors with knowledge of infection prevention are recommending that even after people have received the vaccine, they stay diligent about wearing their masks and social distancing. That’s so that they give their bodies a chance to develop immunity….and also protect the people around them. They list concerns about some of the new variants that have been found locally….and that people are starting to travel again, and some of those are vaccinated while others are not…and also that as people start to gather in larger groups, the odds of catching Covid-19 go back up again, because it’s unclear if all of the variants will respond to the current vaccines.
