Still, if even 2 percent of infections led to long-term problems, that would represent millions of people around the world, which is why more research is important. Until then, long Covid will resemble many other daily risks: Some people will largely ignore it, while others will try to reduce the risk (by wearing a mask indoors, for instance). Both approaches seem reasonable.
… not always used
The U.S., like many other countries, already has most of the tools it needs to defang BA.5. Unfortunately, many people are not using those tools.
Only about half of American adults have received a booster shot. Even fewer have received a second booster. (Anyone 50 and older is now eligible for one, and the Biden administration seems likely to expand eligibility soon.) Jha offers this rule of thumb: If you have not yet gotten a vaccine shot — of any kind — in 2022, consider getting one.
