COVID-19 infections in a Colorado county with a Delta variant surge this spring were more common among fully vaccinated people than in the state's other counties where it was circulating at lower levels, a U.S. Centers for Disease Control and Prevention study released on Friday showed.
The study also found that the Delta variant caused more severe illness. Cases, hospital intensive care unit admissions and deaths were higher in Mesa County, Colorado, than anywhere else in the state, it said.
An estimated "crude efficacy" of COVID-19 vaccines against preventing symptomatic infection among the fully vaccinated people in Mesa County was 78%, versus 89% for other Colorado counties where the variant was less dominant. In another study also published on Friday, CDC data showed that a person infected with COVID-19 who was fully vaccinated is less likely to be reinfected than someone who has had the virus but is unvaccinated.
