The antibodies may disappear in 2 months …

A new study of antibodies neutralizing Covid-19 in patients with a moderate form suggests that the antibodies may disappear after as little as two months.

The question of the combative capacity of antibodies against Covid-19 arose from the start of the epidemic. A new study led by researchers from the Sorbonne, the Pitié-Salpêtrière hospital, Inserm and the Institut Pasteur states that in the event of a moderate form of the disease, the immune system produces antibodies allowing block entry of the virus into cells. However, these protectors gradually disappear and there may not be any traces of them after only two months.

“We followed 26 healthcare workers with mild Covid-19 three weeks, two months and three months after the onset of symptoms,” the study said.
The data of the 26 members of the health staff at Pitié-Salpêtrière were studied from January 28 to March 21, 2020.

“All of these professionals have developed antibodies between two and four weeks after the onset of symptoms,” they point out.
However, this neutralizing activity decreases rapidly and can go as far as disappearing as early as two months after the onset of the disease.

A short-lasting protective effect
Thus, in the case of a moderate form of the disease, antibodies are generated quickly but they have a limited lifespan, which means that the protection against further contamination is short-lived.

However, the researchers highlight the need for barrier gestures and personal protective equipment. They further believe that vaccination against SARS-CoV-2 in humans is likely to have a short-lasting protective effect.
