Additional COVID-19 vaccine boosters are not recommended for patients outside of high-priority groups, according to new international guidance. 

The WHO says booster shots should be reserved for older adults, pregnant women, younger adults with “significant comorbidities”, immunocompromised patients and frontline health workers, who are at greatest risk of severe disease and death.
