“What we’re starting to see now is an uptick in hospitalizations among people who have been vaccinated but not boosted.”
As cases of Covid-19 rise throughout the U.S., health officials warn that an increasing number of fully vaccinated people are being hospitalized or going to the emergency room. The concern about waning immunity against severe Covid infection comes as the Food and Drug Administration is expected to authorize a Pfizer-BioNTech vaccine booster shot for all adults 18 and older.
“What we’re starting to see now is an uptick in hospitalizations among people who’ve been vaccinated but not boosted,” Dr. Anthony Fauci, the director of the National Institute for Allergy and Infectious Disease, said Tuesday in an interview. “It’s a significant proportion, but not the majority by any means.”
On Wednesday, Dr. Rochelle Walensky, the director of the Centers for Disease Control and Prevention, reported a decline in vaccine effectiveness among the elderly and residents of long-term care facilities, many of whom were the first to be eligible to be vaccinated last winter.
“Although the highest risk are those people who are unvaccinated, we are seeing an increase in emergency department visits among adults 65 and older, which are now again higher than they are for younger age groups,” Walensky said Wednesday at a White House Covid briefing.
