The Swedish public health authority puts vaccines with Moderna on pause for people born after 1991. In Norway, FHI advises men under 30 to take Pfizer.

Swedish health authorities say they are doing this to be extra careful. The background is signals of a high risk of inflammation in the heart muscle and heart sac.

These disorders usually go away on their own. They can often be contracted with viral infections. The risk of being hit is very small, according to the news. The decision is provisionally valid until 1 December.

– Very little risk

– Those who have recently been vaccinated with their first or second dose of Moderna’s vaccine do not have to worry. The risk is very small. It is still that we must know what symptoms to be aware of, says state epidemiologist Anders Tegnell in a press release.

These are the symptoms:

• Fatigue and heavy breathing.
• Irregular heartbeat and palpitations.
• Fever and pain in the body.
• A feeling of pressure on the chest.
• It hurts to breathe deeply.
• Pain in the left or middle of the chest.

Norway with advice for men under 30

The Norwegian Institute of Public Health (NIPH) says that men under 30 should check to choose Pfizer’s vaccine (Comirnaty).

-We describe once again our recommendation that young people under the age of 18 who are to be vaccinated are offered Comirnaty regardless of which mRNA vaccine they received as the first dose. Men under the age of 30 should also check to choose Comirnaty when they are to be vaccinated, says Geir Bukholm, director of infection control at the National Institute of Public Health in a press release.

FHI points out that an analyzer from the USA has suggested that myocarditis may be more frequent when using Moderna’s vaccine as a second dose than the vaccine from BioNTech / Pfizer. The figures have so far been small and therefore used.

New monitoring data from Ontario, Canada, confirms that this observation is correct, says FHI. Preliminary data from Norway, Sweden and other countries may indicate the same.

In Sweden, 81,000 people of the current age have received a first dose of Moderna. They will not be offered another dose for the time being. The Public Health Authority is now assessing what to do with this group.

Denmark follows

The Moderna vaccine will also not be given to people under the age of 18 in Denmark.

It states The National Board of Health in Denmark, which votes the National Institute of Public Health in Norway.

In Denmark, children and young people aged 12–17 up to now have mainly been offered the BioNTech / Pfizer vaccine.

– Based on a precautionary principle, we will in future only offer children and young people this vaccine. Not least, I need to use this data to use most of the data for use by children and young people, especially in the United States and Israel.

That’s what Bolette Søborg, who is unit manager at the National Board of Health, says.
