Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky told the White House COVID-19 briefing on Friday that unvaccinated people are “10 times more likely to be hospitalized and 11 times more likely to die “.
Walensky’s announcement comes as three new CDC studies show COVID-19 vaccines still significantly reduce the risk of hospitalization and death amid the Delta variant outbreak.
The first study of U.S. veterans fully vaccinated with Pfizer or Moderna found no change in vaccine effectiveness against hospitalization before and after the emergence of the Delta variant.
The second study of all three vaccines in nine states found that vaccines were 86% safe from hospitalization across all age groups.
A third study of the three vaccines in 13 jurisdictions found that the vaccines also protected participants well against hospitalization and death during the height of the Delta variant wave and before the emergence of the Delta variant.
Among the three studies, the vaccines remained 86-87% effective against hospitalizations related to COVID-19, according to the CDC.
But the efficacy declined further for people aged 65 and over in the last few months before Delta’s flare-up, likely due to the vaccine’s effectiveness waning over time and the strength of the vaccine. Delta variant having an impact on the efficacy of the vaccine.
The three vaccines were also found to have lost some of their effectiveness in preventing mild illnesses in vaccinees, according to ABC News.
