This season's flu vaccine provided "substantial protection" across all age groups, CDC says

The flu shot provided "substantial protection" for all age groups, including elderly and immunocompromised populations, during this influenza season, the Center for Disease Control reported Wednesday.

The Advisory Committee on Immunization Practices presented new findings that showed people who received the influenza vaccination were well protected from "inpatient, emergency department, and outpatient illness among all ages" in the 2022-2023 season. 

It also reduced the chance of hospitalization from Influenza A — the virus that causes flu pandemics — in children by nearly three-quarters, and in adults by nearly half, the CDC said in a press release.
