The U.S. Centers for Disease Control and Prevention (CDC) now recommends people 65 years and older and those who are moderately or severely immunocompromised to receive a second dose of 2024-2025 COVID-19 vaccine six months after their first dose.

The recommendation acknowledges the increased risk of severe disease from COVID-19 in older adults and those who are immunocompromised, along with the currently available data on vaccine effectiveness and year-round circulation of COVID-19.
