Covid vaccine booster doses only needed for high-risk groups, WHO says

Guidance says strong population-level immunity due to infection and vaccination means boosters have less impact

Only high-risk groups should receive ongoing Covid-19 booster doses because strong population-level immunity means ongoing boosting of the general population offers little impact, the latest update from the World Health Organization (WHO) says.

The vaccination guide, from WHO's Strategic Advisory Group of Experts on Immunisation, says each country needs to take into account its own epidemiological situation, stressing that its recommendations are for short-to-medium term planning and subject to change.
