Pfizer and Moderna Covid boosters are now available at pharmacies in the US, while the country has also reinstated its free Covid test program. The CDC and FDA recommend a single dose of the updated vaccine for individuals aged six months and older, with some children eligible for up to three doses. The CDC estimates that the Eris variant is responsible for nearly 30% of Covid cases in the US. Health authorities advise continued mask use to reduce transmission. It is important to seek testing if symptoms of Covid are experienced, and to isolate if testing positive.
