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

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

Will the government continue its momentum and open the fourth dose All French peopleregardless of their age?

The HAS does not recommend it

The vaccination card is no longer mandatory since March 14th. So even if this fourth dose is possible, you no longer have to go to cultural sites and other restaurants, bars, cafes …

But still, the epidemic is not behind us. On April 8, 2022, the incidence rate was still almost 1,400 cases per 100,000 inhabitants. Far from the 3,800 in late January, but much higher than the 547 in early March.

In a statement from mid-March, however, the High Authority for Health (HAS) recommended giving a second booster vaccination only for over 65and not “in the general population”.

Taking into account the various data available and the still limited reviews on the decline in immunization protection over time after a first booster dose, the uncertainties related to the persistence of vaccine efficacy after a second booster dose and the challenges of population acceptance from consecutive and due Given the frequent booster campaigns, HAS does not consider it relevant to currently recommend the administration of a second booster dose in the general population.

Depending on the epidemic

Contacted by This Tuesday, April 12, 2022, the HAS confirmed the words of March: “There will be no generalization for the time being” and added “that the documentation, particularly on this topic, will be published in the coming weeks”.

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

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

“The vaccine should be updated”

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

Therefore no effect on contamination. But it is precisely the level of contamination that decreases in order for the epidemic to stop.

The same observation for Doctor Rossi: “It would be of real interest to allow everyone to benefit from a further booster dose if it reduces contamination”.

However, the infectious disease specialist, who works at the Robert Ballanger hospital in Aulnay, recalls that when contamination levels remain high, “it is mainly weak people who are in the hospital. »

For Henri Agut “that would be necessary the vaccine is updatedespecially since none existed at the time of its creation [le variant] omicron. However, in the week of March 28, 2022, according to Public Health France, Omicron accounted for 99.9% of the contaminations on the territory.

If we had a more efficient vaccine and adapted to Omicron, why not? It looks like it’s not worth it.

Clinical trials along these lines had been announced by Pfizer and Moderna. So patience.
