There is currently no indication that healthy children and adolescents require booster doses of the COVID-19 vaccination, according to the World Health Organization’s chief scientist, Soumya Swaminathan, on Tuesday.

During a news conference, she stated that while there appears to be some fading of vaccine protection against the fast spreading Omicron version of the coronavirus over time, further study is needed to determine who need booster doses.

“There is currently no evidence that healthy children or teenagers require boosters. There is no proof at all “She stated.

Israel has begun offering boosters to children as young as 12, and the U.S. States Food and Drug Administration earlier this month authorized the use of a third dose of the Pfizer and BioNTech COVID-19 vaccine for children aged 12 to 15.

Last week Germany became the latest country to recommend that all children between ages of 12 and 17 receive a COVID-19 booster shot. Hungary has also done so.

Swaminathan said the WHO’s top group of experts would meet later this week to consider the specific question of how countries should consider giving boosters to their populations.

“The aim is to protect the most vulnerable, to protect those at highest risk of severe disease and dying. Those are our elderly populations, immuno-compromised people with underlying conditions, but also healthcare workers,” she said.
