In Denmark, people under the age of 18 will not be offered the Moderna vaccine with caution, the Danish Health Authority said on Wednesday.
He said the data, collected from four Nordic countries, show that there is a suspicion of an increased risk of heart inflammation when vaccinated with Moderna injections, although the number of cases of heart inflammation remains very low.
Preliminary data from the Nordic study have been sent to the European Medicines Agency (EMA) and will now be evaluated.
Sweden and Denmark said they now recommended the Comirnaty vaccine, from Pfizer / BioNTech, in the country.
Norway already recommends the Cominarty vaccine for juveniles and said it was repeating this, noting that rare side effects may be more common for boys and young people, and mostly after taking a second dose.
“Men under the age of 30 should also consider Cominarty choices when getting vaccinated,” said Geir Bukholm, head of infection control at the Norwegian Institute of Public Health, in a statement.
A Finnish health official said Finland expected to announce a decision today.
The EMA approved the use of Comirnaty in May, while Spikevax praised children over 12 in July.
