Unvaccinated people are more than twice as likely to be reinfected with the coronavirus compared to those who are vaccinated, per a study from the Centers for Disease Control and Prevention released Friday.
State of play: The research found that unvaccinated people were "significantly" more likely to get reinfected with COVID — more specifically 2.34 times more.
- Immunity from natural infection is suspected to last roughly 90 days, the CDC said.
- The agency added that the emergence of new variants might affect how long this immunity lasts.
Details: The study involved 246 Kentucky residents who were reinfected between May and June.
- Of note: At the time the study was taken, the Delta variant was not yet the dominant strain in the U.S.
What they're saying: The study's results "suggest that among persons with previous SARS-CoV-2 infection, full vaccination provides additional protection against reinfection. To reduce their risk of infection, all eligible persons should be offered vaccination, even if they have been previously infected with SARS-CoV-2," the CDC said.
