Extremely Rare Side Effect Also Occurs With Successful Pfizer & Moderna Vaccines

Succesful vaccines from Moderna and Pfizer also have a blemish on the blazon. In very rare cases – one in 75,000 times – the vaccines seem to cause inflammation of the heart muscle or the pericardium. The US FDA is the first significant drug authority to confirm this week formally.

 

However, the risk of the condition does not outweigh the benefits of the vaccine.

The condition is less scary than it sounds: an ailment that can cause breathlessness, chest pain and palpitations, and usually heals quickly after treatment with anti-inflammatories – if it doesn’t go away spontaneously. However, the side effect can have unpleasant consequences for vaccine policy. The condition mainly occurs in newly vaccinated young men under the age of 25. That could factor into the debate about whether or not vaccines should be offered to teens.

After a whopping 6.5 million vaccinations in the US, more than 350 young men reported the infection, far more than the handful normally expected by chance. It is striking that the disease occurred much more often after the second injection and slightly more often after vaccination with Moderna than with Pfizer. Women under the age of 30 and men between the ages of 30 and 50 also developed heart infection somewhat more often than expected. But by far, the most reports came from boys and young men over the age of 12.

In any case, in the US, the government agencies and scientists involved emphasize that the inflammation absolutely does not outweigh the benefits of vaccination. But biostatistician Vinay Prasad comments in the professional journal The BMJ: because children themselves do not suffer much from corona, a different risk assessment should apply.

“Vaccination serves two purposes: to protect the person receiving the vaccine and to protect others. We are willing to do things for that second purpose, but not if it does net harm to the individuals.” Prasad, therefore, believes that it is better not to offer the vaccines to young people under 18.

In rare cases, the condition, which is rare in itself, can indeed cause problems. In the US, for example, 22 people had to be hospitalized after they developed a heart infection. Two ended up in intensive care. Two patients in Britain died from the inflammation, although the exact medical details are unknown.

The suspected side effect came to light in young men in Israel as early as April. However, because the inflammations, ‘myocarditis’ and ‘pericarditis’ in jargon, also occasionally occur spontaneously, it was not possible to say with certainty to what extent these cases are the result of the inoculation.
