Coronavirus Reinfection Twice as Likely Among the Unvaccinated, CDC Says

The Centers for Disease Control and Prevention published a new study on Friday revealing that unvaccinated individuals are twice as likely to become reinfected with COVID-19 than people who have been fully inoculated against the rapidly mutating virus.

“Reinfection with human coronaviruses, including SARS-CoV-2, the virus that causes COVID-19, has been documented. Currently, limited evidence concerning the protection afforded by vaccination against reinfection with SARS-CoV-2 is available,” the report’s abstract states.

“Among Kentucky residents infected with SARS-CoV-2 in 2020, vaccination status of those reinfected during May–June 2021 was compared with that of residents who were not reinfected. In this case-control study, being unvaccinated was associated with 2.34 times the odds of reinfection compared with being fully vaccinated,” the CDC said. “To reduce their likelihood for future infection, all eligible persons should be offered COVID-19 vaccine, even those with previous SARS-CoV-2 infection.”

The CDC explained that immunity from natural infection wanes after about 90 days and that vaccines are essential for preventing the coronavirus from making an unwanted comeback.

“These findings 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 agency said, although it noted that “partial vaccination was not significantly associated with reinfection.”

Fortunately – and despite loud and belligerent resistance to vaccinations within the American conservative propaganda sphere – the CDC also announced that as of Friday afternoon, half of the United States’s population has been fully inoculated against the coronavirus.
