Visiting a vaccination center, Jean Castex and Olivier Véran discussed the upcoming establishment of serological tests to identify former Covid patients who may only receive one injection.

A bright sun above the Val-de-Marne and figures looking bright this Monday: 25.5 million people received their first dose of Covid-19 vaccine on the last day of May. The goal of 30 million first-time vaccines by mid-June is certainly still a long way off but seems within reach.

Despite this meteorological and health improvement, Jean Castex and his Minister of Health, Olivier Véran, both traveling to a vaccination center in Saint-Maur-des-Fossés, were keen to preach vigilance. “We must not let our guard down, we are in a pivotal phase,” warned the head of government, on the first day of the opening of vaccination to all adults, unconditionally.

“This week, before the scheduled Defense Council (Wednesday) we will move forward on various subjects. There is obviously the vaccination of children and adolescents of more than 12 years, there is the question of the organization of the vaccination campaign during the summer. And then the question of knowing if we can or not, and in which sanitary conditions, dispense from a second dose of vaccine of the people having had the virus, having developed antibodies “, punctuated Jean Castex.

A new system around serological tests

French people who have been infected with Covid-19 may be concerned without necessarily knowing it: serological tests, which make it possible to detect the presence of antibodies, can indeed reveal cases of former asymptomatic patients.

Earlier in the morning, Olivier Véran explained that he had contacted the health authorities to find out whether it was necessary to inject one or two doses to a person whose test would have revealed a previous infection. “Obviously, we will go on a single dose which is very good news,” he said. “It concerns 5-6 million French people,” he argued.

The minister continued by announcing that “no doubt” would be offered rapid serological tests at the entrance of vaccine centers to identify the people concerned.

This Monday morning, on the airwaves of RMC, Dominique Le Guludec, president of the High Authority of Health had already approached this new device: “We will propose, at the time of the first dose, to prick to see if you have antibodies for determine the need for a second dose. This may prevent a second dose for many people who will be delighted. “

“The further the Covid, the more effective the vaccine”

The High Authority of Health, in an opinion delivered on February 12, had already mentioned the possibility of inoculating only one dose to former patients of Covid-19 and recommended in their case to wait three, or even preferably six months after contamination to perform the single injection. Dominique Le Guludec, president of the Haute Autorité de Santé, reminded Apolline de Malherbe of the guiding principle:

“If you have had the Covid, yes you must be vaccinated … On the other hand, not immediately, we have advised three to six months after a symptomatic form. (…) (These patients) are protected for for a while, they can do it when it suits them, go on vacation, modulate a little … On the other hand, we also know that, with more robust data since our opinion, a dose is enough. or the time between your Covid and the first dose “. “The further it is (the Covid, Editor’s note) the more effective the vaccine,” she continued.
