The researchers analyzed 111 plasma samples from people who have generated antibodies against SARS-CoV-2 and who experienced different levels of disease severity. The result is that 44% of people with Special Data mild or asymptomatic covid-19 develop few antibodies with little neutralizing capacity, while people hospitalized for this disease, on the other hand, generated approximately 10 times more antibodies than those who suffered from it normally. mild form.
The scientists who carried out the study have warned that, according to these results, testing positive in an antibody test could not guarantee protection against SARS-CoV-2 and emphasize the need to maintain precautionary measures, hygiene, masks and distance. physical to avoid new exposures to the virus.
According to the results, 44% of the 29 individuals who suffered mild infection currently have antibody levels below the reliable detection limit. Of these, half do not present any neutralizing activity and are, from this point of view, indistinguishable from uninfected controls, while the remaining 56%, on the other hand, have generated antibodies above the threshold.
