The Centers for Disease Control and Prevention says "the war has changed" against COVID-19 and that the agency should acknowledge that in communications, according to an internal presentation by the agency.
Data in the document, which was first obtained by The Washington Post, underscores the danger posed by the highly-contagious delta variant of the virus that was first spotted in India. In the presentation, dated July 29, the agency does not estimate that vaccinated Americans are at a significantly greater risk of so-called "breakthrough" infections. In fact, it cites recent unpublished data from several of the CDC's ongoing cohort studies that have scrutinized large groups of Americans suggesting vaccine effectiveness remains high months after their second shot, suggesting the Pfizer and Moderna vaccines remain 65-75% effective even against asymptomatic infection.More Related News
Out of air and pinned by an alligator to the bottom of the Cooper River in South Carolina, Will Georgitis decided his only chance to survive might be to lose his arm. The alligator had fixed its jaws around Georgitis' arm and after he tried to escape by stabbing it with the screwdriver he uses to pry fossilized shark teeth off the riverbed, the gator shook the diver and dragged him 50 feet down, Georgitis told The Post and Courier.
