WASHINGTON >> President Joe Biden’s administration is launching a renewed push for COVID-19 booster shots for those eligible, pointing to the enhanced protections they offer against severe illness as the highly transmissible BA.5 variant spreads across the country.

The initiatives include direct outreach to high-risk groups, especially seniors, encouraging them to get “up to date” on their vaccinations, with phone calls, emails and new public service announcements.

All Americans age 5 and over should get a booster five months after their initial primary series, according to the Centers for Disease Control and Prevention. It also says adults ages 50 and older — or those who are immunocompromised — should get a second booster four months after their first.

According to the CDC, tens of millions of eligible Americans haven’t received their first booster.
