An American study claims that in a person vaccinated against Covid-19 who subsequently became infected with the virus, antibody production increases tenfold. This is likely to benefit from “super immunity” to the virus.
Vaccine protection against Covid-19 is kind of the big question right now. While researchers are constantly discovering variants that are more or less resistant to currently circulating vaccines, the vaccine’s efficacy remains the greatest unknown. Thus a person develops antibodies when he is vaccinated or when he is infected with the virus: thus acquiring a certain immunity against Covid-19.

Scientists have paid great attention to the phenomenon of “super immunity”: in certain situations, few people are the target of optimal protection from the virus. According to an American study published last Thursday, December 16 in the magazine Journal of the American Medical Association (JAMA), A person who has been vaccinated against the virus and subsequently becomes infected is more likely to acquire this “super immunity”.
Antibody increased by 1000%.
In practice, according to our colleagues from CNewsThe researchers took a close look at two groups of patients: a first group of people with a full vaccination schedule who contracted Covid-19 and a second group of people who also completed their vaccination schedule, but never contracted the virus.

The first group developed a particularly noticeable amount of antibodies: “An increase of 1,000% and sometimes 2,000%, and therefore a really high immunity. It is almost super immunity,” Professor Vicado J. Tavis, commented at the conclusion of the study, in the publication. Last summer, a study conducted by Centers for Disease Control and Prevention It was concluded that vaccination cut the risk of re-infection in first-time infected people in half.
