The World Health Organisation says it wants to prioritise efforts on vaccinating those facing the greatest threat of severe disease and death from COVID-19.
WHO revises COVID-19 vaccine recommendations
The World Health Organisation has tailored its COVID-19 vaccination recommendations for a new phase of the pandemic, suggesting that healthy children and adolescents may not necessarily need a shot but older, high-risk groups should get a booster between six to 12 months after their last vaccine.
The United Nations agency said the aim was to focus efforts on vaccinating those facing the greatest threat of severe disease and death from COVID-19, considering the high-level population immunity worldwide due to widespread infection and vaccination.
The health agency defined high-risk populations as older adults as well as younger people with other significant risk factors.
For this group, the agency recommends an additional shot of the vaccine either six or 12 months after the latest dose, based on factors such as age and immunocompromising conditions.
