Study: COVID-19 risk for reinfection low 10 months after first infection

June 3 (UPI) -- People who have had COVID-19 are unlikely to be reinfected by the coronavirus for at least 10 months, according to a study published Thursday in The Lancet.

University College London researchers examined the case files of more than 2,000 nursing home residents and staff members who were tracked via antibody testing at 100 nursing homes.

Roughly one-third of the residents and staff tested positive for antibodies, which suggests previous coronavirus infection.

Of 634 people who were infected with COVID-19, reinfections occurred in four residents and 10 staff members, compared to the 93 residents and 111 staff members who had never had the coronavirus but tested positive during the study period.

The findings revealed that residents who had COVID-19 were 85% less likely to test positive 10 months later than residents that had not had the coronavirus. Among staff, those that had tested positive were 60% less likely to receive another positive test than staff that had not already had the coronavirus.

So, natural infection has an 85% efficacy against reinfection... even better than a single dose of a vaccine.

Score one for the anti-vaxxers.

Maybe than a single dose of J&J (or two doses of AZ, which was heavily used in the UK, where the study was done), but not the two dose regimes of Pfizer and Moderna. OTOH, the J&J vaccine, as well as P and M also reduce the severity of Covid for those who still get it. So, immune or much reduced severity, the risk of an unpleasant (or worse) case of Covid for the unvaccinated is much greater.
