Emmanuel Macron had himself sold the wick a few hours earlier, from the north of France where he is traveling.
The High Authority for Health (HAS) issued this late Friday afternoon an opinion recommending the administration of booster doses of the Covid-19 vaccine, most often third doses, to all residents aged between 'at least 40 years old.
Pfizer and Moderna, now banned among people under 30, can be used interchangeably.
Until then, the age limit - taken over by the government - was set at 65, in addition to health professionals and all adults at risk of severe form.
But in his speech of November 9, Emmanuel Macron had already announced an enlargement of the target to 50-64 years.
The government is therefore likely to go further.
"We will have to open the booster dose to people for whom it is effective," said the Head of State on Friday.
Recommended reminders for all in Germany
The HAS examined all the available data, in particular those on the drop in effectiveness of an initial “classic” vaccination schedule (most often with two doses).
Vaccines protect less and less against infection over the months, and probably also against severe forms.
But initial studies confirm that the booster doses strongly raise the level of immunity.

It remains to be seen whether young adults will also be called upon to receive a booster dose in the short or medium term.
In Germany and the United States, the health authorities have just approved additional injections (Pfizer or Moderna) for all adults, without age limit.
Israel, pioneer of additional injections for all, had for its part lowered the age limit week after week last summer, including even teenagers.
About 70% of the eligible population and 80% of the oldest inhabitants have now received a "booster", which has probably allowed the Hebrew country to "break" its very strong epidemic wave.
