Prior COVID Infection Doesn't Guarantee Good Immunity: Study
"Many people, and many doctors, are assuming that any prior exposure to SARS-CoV-2 will confer immunity to reinfection. Based on this logic, some people with prior exposure don't think they need to get vaccinated. Or if they do get vaccinated, they think that they only need the first dose of the two-dose Pfizer/Moderna vaccines," McDade said in a university news release.
"Our study shows that prior exposure to SARS-CoV-2 does not guarantee a high level of antibodies, nor does it guarantee a robust antibody response to the first vaccine dose," he said. "For people who had mild or asymptomatic infections, their antibody response to vaccination is essentially the same as it is for people who have not been previously exposed."
Study is antibodies, headline is immunity. Terrible, intentional I would assume.
But hey, it was 27 samples. Wow.
