Health Officials Mull Widening Additional Booster Eligibility as COVID Cases Rise
The waning long-term effectiveness of vaccines may mean additional boosters
Health officials are considering extending the eligibility for a second COVID-19 vaccine booster dose to people under 50 amid a steady rise in cases, with the United States seeing a threefold increase over the past month.
The U.S. Food and Drug Administration had in late March authorized a second booster dose of the Moderna and Pfizer vaccines for people aged 50 and older, citing data showing waning immunity and the risks posed by Omicron variants of the virus.
"With regard to a fourth dose for those under the age of 50, that is going to require action from the FDA, and we're in conversations there," said Rochelle Walensky, the director of the U.S. Centers for Disease Control and Prevention, on Wednesday.
