In an attempt to defeat the Covid-19 and its many variants, many rely on these new vaccines to ARN messenger, such as that of Pfizer Laboratories and Modern. These vaccines would be much more adaptable than the others.

Faced with the threat of variants, they seem to be our best weapon: the vaccines ARN messenger. Those of Pfizer laboratories and Modern use this technology, soon joined by CureVac. The great advantage of vaccines ARN messenger is that they are adaptable quickly and easily. “Clinical trials have already started with second generation RNA vaccines that are directed against both the initial virus and the major variant viruses“, explains Jean-Michel Pawlotsky, head of the biology department, at the hospital Henri-mondor from Créteil (Val de Marne).
The principle ofARN messenger is innovative: during vaccination, a piece of the genetic code of the virus is injected, theARN. It is used to make protein S, these small spikes typical of the coronavirus. This will allow our body to defend itself against disease. The method is effective over 90%. Few side effects have been observed with this technology, which also raises hope for other pathologies.
