'Getting the vaccine is the best way to protect yourself and others around you, especially as the more contagious Delta variant spreads around the country,' said CDC Director Dr. Rochelle Walensky.
survivors who are unvaccinated are more than twice as likely to get reinfected with the virus, the Associated Press reported.
Scientists say infection does generally leave survivors protected against a serious reinfection at least with a similar version of the virus, but blood tests have signaled that protection drops against worrisome variants.Researchers studied Kentucky residents with a lab-confirmed coronavirus infection in 2020, the vast majority of them between October and December. They compared 246 people who got reinfected in May or June of this year with 492 similar survivors who stayed healthy.
That suggests natural immunity from earlier infection isn't as strong as the boost those people can get from vaccination while the virus evolves, she said.
