There’s “no evidence right now” that suggests healthy children and adolescents need booster shots to supplement their Covid-19 vaccinations, World Health Organization Chief Scientist Dr. Soumya Swaminathan said Tuesday.
Swaminathan said the agency’s advisory group, called Sage, or the Strategic Advisory Group of Experts on Immunization, will meet later this week to consider how countries should think about giving booster shots.
“The aim is to protect the most vulnerable, to protect those at highest risk of severe disease and dying, those are our elderly population, immunocompromised with underlying conditions and also health care workers,” Swaminathan said WHO media briefing.
Dr. Michael Ryan, executive director of the WHO’s health emergencies program, said the agency still hasn’t figured out how often or how many doses people will ultimately need.
“I think people do have a certain fear out there that this booster thing is going to be like every two or three months and everyone’s going to have to go and get a booster. And I don’t think we have the answer to that yet,” Ryan said.
He said scientists may eventually redefine how many doses are required in the primary series of Covid shots. While most healthy people may need just two shots, he said the elderly or immunocompromised may need three or four.
