An international group of vaccine experts, including officials from the Food and Drug Administration (FDA) and World Health Organization (WHO), said that there is no evidence to suggest that the general population needs COVID-19 vaccine booster shots.
The authors warned that if booster shots are introduced too soon, they may cause more side effects in the general population, including myocarditis or Guillain-Barre syndrome. Should that occur, the researchers said, it would create even more problems with vaccine acceptance in the general population.
The paper was published Monday in The Lancet medical journal and was co-authored by Marion Gruber and Phil Krause, two top FDA officials in charge of regulating and approving vaccines. Both Gruber and Krause are slated to depart the FDA in the coming weeks, the agency confirmed about two weeks ago.
