A nationwide study in France confirmed that there is a slight risk of cardiac inflammation associated with mRNA vaccines, Reuters news agency reported. The study then forced the authorities to advise people against the use of the Moderna Covid vaccine or jabs for people under 30.
According to the report from France Local media, France suspended the use of Moderna for all population groups on October 15th after a number of Scandinavian countries warned of a possible link between the American-made vaccine and heart inflammation among young people.
An independent medicines safety group, Epi-Phare, that works with the French government has noted that cases are rare and do not cast doubt on the effectiveness. France’s public health authority has recommended giving Phizer’s comirnaty vaccine to people under 30 instead of Moderna Spikevax jab, citing that it carries comparatively higher risks.
Earlier, the European Medicines Agency acknowledged that there was a potential link between heart inflammation and both Moderna and Pfizer-BioNTech vaccines. But it emphasized that such cases were very rare and that the benefits of vaccination outweigh the risks.
Haute Autorite de Sante, a french medical regulator said, “Within the population aged under 30, this risk appears to be around five times lesser with Pfizer’s Comirnaty jab compared to Moderna’s Spikevax jab.”
On the other hand, HAS suggests that among the over-30s, an initial vaccination with the Moderna vaccine offered marginally better protection than the Pfizer alternative.
However, last month, the booster dose of the Moderna vaccine was approved for all age groups over 18 and it was recommended at least six months after the second dose.
Moreover, for persons aged over 30, the authority explicitly recommended the use of the Moderna vaccine, saying its effectiveness was slightly superior.
