The Delta coronavirus variant surging across the United States appears to cause more severe illness and spread as easily as chickenpox, according to an internal document from the US Centers for Disease Control and Prevention.

"The bottom line was that, in contrast to the other variants, vaccinated people, even if they didn't get sick, got infected and shed virus at similar levels as unvaccinated people who got infected," Dr. Walter Orenstein, who heads the Emory Vaccine Center and who viewed the documents, told CNN.

"Vaccines prevent more than 90% of severe disease, but may be less effective at preventing infection or transmission," it reads.
