The effectiveness of the currently available COVID-19 vaccines plunged to near zero within months, according to U.S. Centers for Disease Control and Prevention (CDC) data presented on June 5.
Estimated shielding among adults aged 18 to 64 against visits to emergency departments and urgent care facilities turned negative beyond 120 days after peaking at 52 percent, an analysis of data from the CDC’s VISION network found. Protection for those 65 and older was pegged at 9 percent 120 days and later following receipt of one of the vaccines, after peaking at 47 percent.
