can you find a verified source link that such a study was actually conducted when and by whom? ” study involving 1.7 million children has found that myocarditis and pericarditis only appeared in children who had received Covid mRNA vaccines. no unvaccinated participant in the group suffered from these heart-related problems. “

Addressing “Rare” and “Mild”

1. How was “rare” measured?

• In the referenced study, “rare” was determined by calculating the incidence rates of myocarditis and pericarditis among vaccinated children. For instance, the study reported:

• 2.7 cases per 100,000 doses after the first mRNA vaccine dose.

• 1 case per 100,000 doses after the second dose.

• These rates are considered rare when compared to the overall vaccinated population.

2. How was “mild” measured?

• “Mild” was assessed based on clinical outcomes, such as:

• Duration of hospitalization (if needed, typically two days or less).

• Recovery without significant long-term damage or dysfunction.

•

Lack of deaths or severe complications in these cases

• Mild myocarditis in this context was described as transient inflammation that resolved with standard treatment or on its own. Representation Analysis

3. (a) Misrepresentation: •

The data was misrepresented in some social media claims and blogs, which falsely stated that millions of children suffered severe heart defects after vaccination. These claims misinterpreted the study population size (1.7 million children) as the number of cases .

• Additionally, calling mild myocarditis “severe heart defects” was factually incorrect, as the observed cases did not involve lasting damage or dysfunction.

4. (b) Overrepresentation:

• The rarity of the conditions was exaggerated in discussions that omitted the denominator (e.g., total vaccinated individuals) and emphasized the absolute number of cases rather than the incidence rate.

5. (c) Underrepresentation:

• Critics have argued that observational studies like this one may underrepresent risks because they rely on healthcare records. Cases that were not severe enough to require medical attention might not have been captured. Furthermore, unvaccinated individuals may be less likely to seek care, potentially skewing comparisons

6. (d) By whom?

• Misrepresentation was mainly seen in:

• Social media influencers and websites known for spreading vaccine misinformation, which amplified the claims without context.

• Some advocacy groups opposing vaccination mandates, who selectively highlighted the myocarditis findings while ignoring the study’s broader conclusions about vaccine benefits.

Summary

The size and age range of the unvaccinated control group varied depending on the study. In the OpenSAFELY analysis, which compared vaccinated and unvaccinated individuals, the control group included previously unvaccinated adolescents and children matched by factors such as age, sex, and region. For example:

• Among adolescents aged 12-15 years, 820,926 previously unvaccinated individuals were included.

• In children aged 5-11 years, 283,422 unvaccinated individuals were studied .

Another UK study examining myocarditis and pericarditis after COVID-19 mRNA vaccination used large NHS datasets but did not explicitly detail the exact number of unvaccinated individuals. However, they stratified outcomes by vaccination status, age, and other demographics to include unvaccinated person-time contributions during the analysis .
