Unvaccinated: twice the risk for second Corona infections

Unvaccinated people are more than twice as likely to become reinfected with Covid-19, according to the U.S. Centers for Disease Control.

The U.S. Centers for Disease Control (CDC) currently recommends that all persons eligible for Corona vaccination receive a shot – regardless of whether or not they have already survived an infection with the pathogen. In evaluating recent data, the CDC now sees this as reinforced.

A new study examined 246 Kentucky adults who were re-infected with SARS-CoV-2 in May and June of this year, having previously contracted it in 2020. They were matched with 492 control group participants who were identical in gender, age and time of first positive Corona test.

The analysis found that unvaccinated individuals had a 2.34-fold higher risk of re-infection than individuals who were fully immunized with Pfizer, Moderna or Johnson & Johnson vaccines.

Immunity and new variants
The duration of immunity acquired through infection remains poorly understood and could be compromised by new viral variants, the paper says. For example, laboratory studies have shown that blood samples from individuals previously infected with the original wild-type variant of the novel coronavirus showed a weak antibody response in the beta variant, which first appeared in South Africa.

The current study was conducted before Delta became the predominant viral variant in the United States. In Austria, the National Vaccination Board recently began recommending vaccination for convalescents as early as about four weeks after infection – to protect against more contagious virus variants like Delta.
