WHO revises Covid-19 vaccine recommendations for Omicron-era

GENEVA: The World Health Organization 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 6 to 12 months after their last vaccine.

The UN 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.
