Vaccines that are re-contaminated develop other antibodies?

While vaccines protect against coronavirus, especially from severe forms of Covid-19, we also know that they do not always prevent re-contamination by SARS-CoV-2. But do people who are vaccinated and re-contaminated produce new antibodies?

Concretely, vaccines allow the immune system to respond to and defend against viruses. This is also the case if we get sick with Covid-19 again.

After the full vaccination schedule, “usually, we developed antibodies, which we explained to CNEWS, Béhazine Combadière, director of research at Inserm. However, the amount was not enough if the recontamination was done,” the scientist added.

In this context, still according to the explanations of the specialist who is also a member of the Center for Immunology and Infectious Diseases of the Sorbonne University, in the case of recontamination, “the immune system that has previously seen the virus, knows what immune response should come.” The immune system has retained a memory The vaccine, therefore, will only multiply, that is, recreate the cells that have recognized the antigen (the substance that allows the formation of antibodies, editor’s note) that will overcome (the virus).”

“It’s like we’re doing 2NS vaccination”

According to the Béhazine Combadière website, the new contamination “meaning there wasn’t enough” of the antigens. Thus, the immune system produces more cells to produce antibodies. “It’s like we’re doing 2NS vaccination,” she said.

However, the new infection with the Covid-19 virus is not due to a lack of efficacy of the vaccine, and its effect on the patient may depend on “his health condition, weight, other nearby diseases, and the genetic factor…,” the Inserm Director’s joint. There are many factors responsible for the lack of Homogeneity of individual responses.

Thus, some people can produce a lot of antibodies and others less. But the scientist said that after vaccination, there is no “non-responsive” immune system. In the end, she concluded, “It’s like different diseases, some people will respond strongly (to the vaccine) and some people will respond less.”
