October 23, 2024 – Today, CDC Director Mandy Cohen endorsed the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendation for 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. These updated recommendations also allow for flexibility for additional doses (i.e., three or more) for those who are moderately or severely immunocompromised, in consultation with their healthcare provider (a strategy known as shared clinical decision making).

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. The recommendation also provides clarity to healthcare providers on how many doses should be given per year to people who are moderately or severely immunocompromised and is meant to increase coverage of this second dose for that group.

Data continues to confirm the importance of vaccination to protect those most at risk for severe outcomes of COVID-19. Receiving recommended 2024-2025 COVID-19 vaccines can restore and enhance protection against the virus variants currently responsible for most infections and hospitalizations in the United States. COVID-19 vaccination also reduces the chance of suffering the effects of Long COVID, which can develop during or following acute infection and last for an extended duration.

CDC and ACIP will continue to monitor COVID-19 vaccine safety and effectiveness. CDC continues to recommend that everyone stay up to date on their COVID-19 vaccines, especially people ages 65 years and older and those with weakened immune systems.

The following statement is attributable to CDC Director Dr. Mandy Cohen:

“This vote allows people to make the best decisions possible to keep themselves and their loved ones safe from COVID-19. CDC will continue to educate the public on how and when to get their updated vaccinations so they can risk less severe illness and do more of what they love.”
