As the virus continues to mutate, CDC clinical advisers are urging Americans to roll up their sleeves to get vaccinated annually.

All Americans 6 months and older are expected to receive one of the new Covid-19 vaccines when they become available this fall, clinical advisers from the Centers for Disease Control and Prevention said Thursday.
The advice comes as the country faces a summer Covid wave, with infections in at least 39 states and territories.
Most Americans have gained degrees of immunity to the coronavirus through repeated infections or vaccine doses, or both. The vaccines now offer a slow booster and remain effective for a few months as immunity wanes and the virus continues to evolve.
Across all age groups, however, a large majority of Americans hospitalized with Covid received one of the vaccines introduced last fall, according to data presented at a meeting of the CDC’s Advisory Committee on Immunization Practices.
“Professionals and the general public don’t realize how much this virus has mutated,” said Carol Hayes, the committee’s liaison officer with the American College of Nurse Midwives. “You want this year’s vaccine to oppose this year’s strain of the virus. “
A Novavax vaccine will target JN. 1, the variant that was prevalent for months in winter and spring. The rollouts to be carried out through Pfizer and Moderna are aimed at KP. 2, which until recently was on the verge of adapting to the dominant variant.
