The High Authority for Health now advises against vaccinations with Moderna's vaccine for those under 30 years of age because of a possible increased risk of myocarditis in the youngest. In a press release, the HAS indicates that the latest data available in France "confirms the risk of the occurrence of very rare cases of myocarditis with favorable evolution" after vaccination against Covid-19. However, these very rare cases of inflammation of the heart, which are easily treated when properly managed, are "five times less" in those under 30 vaccinated with Pfizer-BioNTech rather than with Moderna, according to HAS.
The HAS therefore now recommends to vaccinate those under 30 only with the Pfizer-BioNTech vaccine "whether it is a primary vaccination or a booster".
