Those who have recovered from COVID-19 who have not been vaccinated might have more than double the chance of reinfection than those who have been inoculated, according to a new study published by the Centers for Disease Control and Prevention.
The study looked at hundreds of Kentucky residents who were infected with the coronavirus in 2020 and compared the vaccination status of those who were re-infected from May to June 2021. Researchers found that those who were not vaccinated had 2.34 times the odds of reinfection compared with those who were fully vaccinated.
Study authors concluded that “to reduce their likelihood for future infection, all eligible persons should be offered COVID-19 vaccine, even those with previous SARS-CoV-2 infection.”
Researchers also noted that “the emergence of new variants might affect the duration of infection-acquired immunity.”
