Updated versions of the mRNA vaccines roll out this week. Experts say they offer good protection against current COVID variants. Who should get them, and when's the best time to roll up your sleeve?
Vaccines for a fall immunization drive against COVID-19 just got the green light from the Food and Drug Administration. The agency says the vaccines can protect people, as hospitalizations tick up.
The Food and Drug Administration appears poised to make available the COVID-19 vaccines that target omicron as a second booster for people with weak immune systems and those ages 65 and older.
Updated COVID boosters are now available for anyone age 12 or older. The CDC is urging anyone who is eligible to sign up but some vaccine experts say some people might want to wait.
People can get the Moderna booster if they're 18 or older, and the Pfizer-BioNTech version if they're 12 and up. In both cases, they must wait at least two months since their last COVID vaccine.
The new shots from Moderna and Pfizer-BioNTech target both the original strain of the coronavirus and the omicron BA.4/BA.5 subvariants that most people are catching now.
The Biden administration may scrap plans to expand eligibility for second boosters to younger adults. Instead, it's trying to speed up the next generation of boosters targeting the omicron variant.
Health officials argue the protection of the COVID vaccine booster wanes over time and say some people need a second booster. But other infectious disease experts say three shots are enough for now.
