New Guidance From CDC on Vaccines for the Elderly

Arund 98% of the US population has some kind of immunity to Covid-19, whether from infection, vaccination, or both, according to the CDC. But health experts say this only gives some protection against infection or severe disease. In response, the CDC this week recommended people age 65 and older should get an additional dose of the current Covid-19 vaccine. The current Covid-19 vaccine, which was updated last fall, is considered highly effective and may cut the chances of getting a symptomatic infection by half. This comes as the CDC is considering a shift to its Covid-19 isolation guidance to say that people no longer need to isolate once they have been fever-free for 24 hours and their symptoms are mild or improving.
