breakthrough covid breaks into this blog

"Breakthough covid" is typically a mild case that one can get after being fully vaccinated. Masha Gessen wrote about getting such a case for The New Yorker, and others have described it as well. It sounds like vaccination is not at all perfect immunity although it seems to be a reason that cases and deaths have declined in the United States and United Kingdom. In better news, vaccines are also showing an ability to improve the lives of those with "long covid"—enduring symptoms that have been known to stretch the illness out over months.
