Most people don’t need an additional COVID-19 vaccine booster, the World Health Organization (WHO) stated in a March 28 update.
People designated as high priority, including older adults and people with significant comorbidities, such as diabetes and immunocompromising conditions such as having received an organ transplant, are being advised by the U.N. organization to get an additional booster 6 to 12 months after their most recent dose. The group includes adults older than the age of 60.
