France: Due to concerns about the risk of myocarditis, a rare heart inflammation, France has become the fifth European country to advise people under 30 not to use the Moderna Covid-19 vaccine. According to the Daily Mail, the country's Public Health Authority (Haute Autorite de Sante) recommended that those under the age of 30 get the Pfizer-BioNTech Covid vaccine instead of the Moderna vaccine.

Denmark, Iceland, Finland, and Sweden had previously either prohibited or restricted the use of the Moderna vaccine in young adults. Despite mounting concerns about the vaccine in Europe, the US Food and Drug Administration (FDA) has continued to approve the shots.

"This risk appears to be around five times lower in the population under 30 with Pfizer's Comirnaty jab compared to Moderna's Spikevax jab," the Haute Autorité de Sante has stated. The health department does not have the authority to prohibit the use of drugs, but it can advise against it.

The data indicates "an increased risk of side effects such as inflammation of the heart muscle or the pericardium" - the double-walled sac containing the heart and the roots of the main vessels, according to Sweden's Public Health Agency. Sweden became the first country to halt the use of the Moderna Covid-19 shot in people born after 1990 in October.
