Rising rates of flu, Covid and RSV prompted the agency to urge clinicians to push for more vaccinations.

Not enough Americans are being vaccinated against Covid, the flu and RSV to stem rising numbers of the respiratory illnesses, the Centers for Disease Control and Prevention said Thursday.

The agency issued a health alert to doctors across the country, warning that low vaccination rates amid “ongoing increases in national and international respiratory disease activity” could strain U.S. health care systems in the coming weeks, and called on doctors to encourage their patients to get the shots immediately to protect them for the remainder of the season.
