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.
