Study: COVID-19 vaccine is more dangerous to children's health than the disease itself

American researchers say adolescents are more likely to develop vaccine-related myocarditis (more on this side effect can be read here) than get to the hospital with Covid.

American scientists say healthy boys are more likely to be admitted to hospital with the rare side effect of the Pfizer / BioNTech Covid vaccine, causing inflammation of the heart, than Covid itself.

Analysis of medical data shows that boys between the ages of 12 and 15 without any underlying medical conditions are four to six times more likely to develop vaccine-dependent myocarditis than in a hospital with Covid over a four-month period.

Most children who have experienced this rare side effect develop symptoms within a few days of the second Pfizer / BioNTech vaccine, although a similar side effect occurs with Moderna. According to the authors, about 86% of the affected boys required hospitalization.

Saul Faust, professor of pediatric immunology and infectious diseases at the University of Southampton, said the findings justify the UK's Joint Vaccines and Immunization Committee's cautious approach to vaccines for adolescents.

The JCVI has not recommended vaccinating healthy children between 12 and 15 years of age, but has referred the matter to the UK's chief medical officer, who is expected to make a final decision next week. Children between the ages of 12 and 15 who are particularly vulnerable to Covid or who live with those at risk are eligible for the vaccine.

In the latest study, which has yet to be peer-reviewed, Dr Tracy Høeg from the University of California and colleagues analyzed adverse reactions to Covid vaccines in children aged 12 to 17 years in the US during the first six months of 2021. They assess the incidence of myocarditis. After two shots of the Pfizer/BioNTech vaccine, the rate was 162,2 cases per million for healthy boys aged 12 to 15 years and 94 cases per million for healthy boys aged 16 to 17 years. The equivalent rates for girls were 13,4 and 13 cases per million, respectively. At current rates of infection in the US, the risk of a healthy teenager being admitted to hospital with Covid over the next 120 days is about 44 in a million, they said.

How reliable the data are and whether similar numbers can be seen in the UK if healthy children between 12 and 15 years of age are vaccinated is unclear: vaccine reactions are reported differently in the US, and vaccinations are given at longer intervals in the UK. The incidence of myocarditis after Covid vaccination is only six per million Pfizer / BioNTech shots, according to the UK drug regulator.

So far, British children have not been hospitalized for Covid in large numbers and may not be at high risk of prolonged Covid. While a recent Clock study found that about 14% of children who contracted Covid may still have symptoms 15 weeks later, at a level fatigue is not affected. This suggests that children can be spared some of the most debilitating symptoms seen with long-term Covid in adults.

The vast majority of myocarditis occurs after the second dose of the vaccine, so single shots can protect children and further reduce the risk of side effects.

“Although myocarditis after vaccination is extremely rare, we may be able to change the first or second dose or combine vaccines differently to avoid the risk altogether once we better understand the physiology,” Professor Faust said. “In general, there is no urgent medical need to immunize children, although if schools fail to consistently support education for the vast majority, the overall balance may change. If the NHS offers a vaccine to my two teenage children, my GP wife and I let's not hesitate to let them get vaccinated. "

Professor Adam Finn, JCVI member at the University of Bristol, said: “I support the JCVI's recommendation that healthy children 12 to 15 years of age should not be vaccinated at this time for reasons of risk and health benefits. Given the current uncertainty, rare harm may outweigh modest benefits. "

The MHRA said it is closely monitoring all available data on the potential risk of myocarditis and pericarditis following Covid-19 vaccination. “We conclude that the Covid-19 vaccines produced by Pfizer/BioNTech and Moderna may be associated with a small increase in the risk of these very rare conditions. Cases were generally mild and the vast majority recovered with simple treatment and rest,” they added.

The spokesperson said the latest study was reviewed by the government's independent advisory body, the Covid-19 Vaccine Risk Reduction Expert Working Group, which found that interpretation of the results was limited by the fact that the study did not take into account differences in treatment methods when comparing hospitalization rates. between Covid-19 infections and myocarditis and pericarditis after vaccination, and there was no estimate of the severity and duration of illness after hospitalization.

“There are safety monitoring strategies in place for individuals under 18 years of age, including monitoring for myocarditis and pericarditis occurring after vaccination and the long-term outcome of these effects. The MHRA continues to closely monitor the safety of Covid-19 vaccines,” the spokesperson added.
