Unsurprisingly, the government formalizes this Tuesday that France will now do without the Moderna vaccine among young people.
This announcement, which appears in a document from the Ministry of Health sent to all professionals, follows the recommendation of the High Authority for Health (HAS), issued Monday evening.
It is similar to that taken by several northern European countries, such as Finland.
The HAS in particular relied on a French study conducted by the Epi-Phare group and published a few hours earlier on Monday.
All patients aged 12 to 50 and hospitalized following myocarditis or pericarditis from May 15 to August 31, i.e. 919 and 917 cases respectively, were followed.

The risk of myocarditis and pericarditis appeared particularly high after the second dose of Moderna vaccine in young men aged 12 to 29, with one case hospitalized for 7600 injections within seven days of the injection.
“From now”, therefore, only Pfizer should be administered to children under 30 years of age.
The benefit / risk ratio not called into question
"This opinion in no way calls into question the use of the Moderna vaccine as part of the vaccination campaign" and "the HAS continues to recommend its use in people over 30 years of age, given its reassuring safety profile and its very good efficiency, ”adds the Ministry of Health.
"This risk, which remains rare and resolute, does not call into question the extremely favorable benefit / risk ratio of vaccines against Covid-19", he continues.
The document sent to all health professionals also confirms, with regard to booster injections, that "the doses should be 0.25 mL and therefore contain 50 micrograms of messenger RNA".
Or half-doses compared to those used for the first and second initial injections.
