Finland joins Sweden and Denmark in pausing use of the Moderna COVID-19 vaccine in young people over fears the shots are causing rare heart inflammation
- Finland has paused use of the Moderna COVID-19 vaccine in males under the age of 30 over fears of rare heart inflammation
- Young men and boys will instead be offered the Pfizer-BioNTech vaccine
- The Nordic nation joins nearby Denmark and Sweden in pausing use of vaccine in young people
- Sweden will no longer allow anyone born after 1990 to receive the Moderna shot and no one under age of 18 will be able to receive the shot in Denmark
- The CDC has warned that heart inflammation is a potential side effect of the vaccine when used in young males
- A recent study finds that people who contract Covid are much more likely to develop heart inflammation that those who receive the vaccine
Finland has become the latest Nordic nation to pause use of the Moderna COVID-19 vaccine in young people due to fears that the shots are causing rare heart inflammation.
The Finnish Institute for Health and Welfare said on Thursday that authorities won’t give the vaccine to males under age 30, and they will be offered the Pfizer-BioNTech immunization instead.
The government agency said it found that young men and boys were at a slightly higher risk of developing myocarditis.
It comes after health officials in Sweden and Denmark made a similar decision earlier this week.
In Sweden, the Moderna jab will no longer be available to any one born after 1990, or those aged 30 and younger.
Denmark has restricted access to the vaccine to anyone under the age of 18.
Norway, another Nordic country, has not taken as drastic action as its neighbors, with health officials urging people under 30 to opt for the Pfizer vaccine instead.
All four countries based their decision on an unpublished study with Sweden’s Public Health Agency saying that it signals ‘an increased risk of side effects such as inflammation of the heart muscle or the pericardium’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.
It added: ‘The risk of being affected is very small.’

Myocarditis and pericarditis, both types of inflammation of the heart, are known side effects of the Covid vaccines, and the Centers for Disease Control and Prevention (CDC) even warns that the condition may develop in young males after vaccination.
Heart inflammation is also a symptom of many viral infections like COVID-19, though, and the likelihood of developing the inflammation after infection is much higher than it is after vaccination.
The Swedish health agency said it would pause using the shot for people born in 1991 and later as data pointed to an increase of myocarditis and pericarditis among youths and young adults who had been vaccinated.
The pause will last until December 1.
Those conditions involve an inflammation of the heart or its lining.
‘The connection is especially clear when it comes to Moderna’s vaccine Spikevax, especially after the second dose,’ the health agency said.
A Moderna spokesperson said in an email the company was aware of the decisions by regulators in Denmark and Sweden to pause the use of its vaccine in younger individuals because of the rare risk of myocarditis and or pericarditis.
‘These are typically mild cases and individuals tend to recover within a short time following standard treatment and rest,’ they wrote.
‘The risk of myocarditis is substantially increased for those who contract COVID-19, and vaccination is the best way to protect against this.’
According to one U.S. study that has yet to undergo peer review young males under 20 are up to six times more likely to develop myocarditis after contracting COVID-19 than those who have been vaccinated.
Denmark said that, while it used the Pfizer-BioNTech vaccine as its main option for people aged 12 to 17 years, it had decided to pause giving the Moderna vaccine to people below 18 according to a ‘precautionary principle’.
In June, the CDC issued a warning that young males were at an increased risk of myocarditis after receiving the vaccine.
The label for both the Pfizer and Moderna vaccines were changed in the U.S. to reflect the warning, though usage was never paused.
Cases of inflammation after vaccination are rare, though they do occur often enough to concern regulators.
A recent study from Kaiser Permanente Southern California found that around seven out of every one million people that receive a two-shot COVID-19 vaccine will develop myocarditis.
People who receive the Covid vaccine are seven times as likely to develop heart inflamation after the second dose of the jab when compared to the first, finds a recent study by KPSC. Those who are unvaccinated are significantly more likely to develop myocarditis, however
The same study found that 47.5 out of every one million Covid patients experience heart inflammation.
While myocarditis will often resolve itself, it can be dangerous.
Heart inflammation can often lead to fatigue, shortness of breath and chest pain for patients.
People with inflamed hearts are at a higher risk for heart failure, heart attacks and strokes.
Attempting strenuous physical activity with an inflamed heart could also potentially lead to sudden cardiac arrest, or even death.
