In mid-March, Prime Minister Jean Castex announced the opening of the fourth dose (the second booster dose) of the anti-Covid-19 vaccine over 80.

At the beginning of April, it was the turn of Olivier Véran, Minister of Health, to announce that those over 60 could now get a second booster dose.

Will the government continue its momentum and open the fourth dose to all frenchregardless of your age?

HAS does not recommend it.

the vaccination pass no longer mandatory since March 14. Thus, although this fourth dose is possible, it will no longer be necessary to go to places of culture and other restaurants, bars, cafes…

But anyway, the epidemic is not still not behind us. As of April 8, 2022, the incidence rate was still almost 1,400 cases per 100,000 population. A far cry from the 3,800 at the end of January, but well above the 547 at the beginning of March.

Inside a note from mid marchthe High Health Authority (HAS) recommended the administration of a second booster dose, but only for over 65sand not “in the general population”.

Taking into account the various data available and the still limited retrospective on the decline over time in the protection of the vaccine with a first booster, the uncertainties related to the persistence of the efficacy of the vaccine with a second booster and the challenges of acceptability by the population of successive and repeated vaccinations. frequent booster campaigns, HAS considers that it is not currently relevant to recommend the administration of a second booster dose in the general population.

Depending on the epidemic situation

contacted by This Tuesday, April 12, 2022, the HAS confirmed the words of March: “There will be no generalization for the moment”, adding “that the documentation, in particular on this subject, will be released in the coming weeks”.

On the side of the General Directorate of Health (DGS), also questioned by“it’s not planned.”

On the other hand, it insists that “a possible generalization of the second booster dose in the general population obviously it would depend on the evolution of the epidemic situationbut also the opinions of the scientific authorities (COSV, HAS) that could be issued”.

“The vaccine needs to be updated”

According to Henri Agut, former director of the Pitié-Salpêtrière virology department, contacted by“It seems that immunity lasts a few months and only protects against severe forms” of the virus.

Therefore, it has no effect on contamination. However, it is precisely that the level of contamination decreases for the epidemic to end.

Same observation for Dr. Rossi: “there would be a real interest in allowing everyone to benefit from another booster dose if it reduced contamination.”

The infectious disease specialist who works at the Robert-Ballanger hospital in Aulnay, however, recalls that if contaminations remain high, “it is mainly frail people who are in hospital. »

For Henri Agut, “it would be necessary that the vaccine is up to dateespecially since at the time it was created, there was no [le variant] Omicron. However, in the week of March 28, 2022, Omicron accounted for 99.9% of the contaminations in the territory, according to Public health France.

If we had a more efficient vaccine adapted to Omicron, why not? As it is, it’s not worth it.

Clinical trials in this direction had been announced by Pfizer and Moderna. Patience, then.
