A large study examining COVID-19 outcomes in adolescents offers a clearer picture of how vaccination affected infection, hospital visits, and rare side effects during the study period.
Researchers followed more than 820,000 adolescents who had not previously been vaccinated and compared their outcomes over a 20-week period with those who received a COVID-19 vaccine.
A key finding from the study centered on heart-related side effects, specifically myocarditis and pericarditis, and where they appeared during the analysis period.
Researchers reported that cases of myocarditis and pericarditis were documented only among adolescents who received COVID-19 vaccinations. No cases of either condition were identified in the unvaccinated comparison groups included in the study. This distinction was consistent across the populations analyzed, making it one of the clearest contrasts observed in the results.
Myocarditis and pericarditis are forms of inflammation affecting the heart muscle and the surrounding heart lining. Symptoms can include chest pain, shortness of breath, and irregular heartbeat, and while many cases resolve with treatment, the conditions are taken seriously because they involve the heart. The study tracked these diagnoses using medical records during the follow-up period.
The absence of documented myocarditis or pericarditis cases in the unvaccinated groups stood out because the study included hundreds of thousands of adolescents, providing a large comparison base. This allowed researchers to observe even uncommon outcomes when they occurred.
The study did not report COVID-19–related deaths in any group and noted that severe illness was uncommon overall. However, the heart inflammation findings highlight a specific outcome that appeared exclusively in vaccinated participants during the study window.
Researchers noted that continued monitoring is important to better understand the frequency, severity, and long-term outcomes of myocarditis and pericarditis following vaccination, particularly in younger populations.
The U.S. Food and Drug Administration is planning to add a “black box” warning to COVID-19 vaccines.
A boxed, or “black box,” warning is the FDA’s most serious safety alert and is displayed at the top of a drug’s prescribing information. It is reserved for risks that may include death, life-threatening complications, or severe and potentially permanent harm.
In some cases, the warning is used when a drug’s risks may be reduced by limiting its use to specific populations or circumstances, requiring clinicians to carefully weigh potential dangers against the treatment’s benefits.
Many social media influencers have taken to Instagram and X to express their frustration about being ‘correct’ about the vaccines from the start. One man called for any and all of those responsible for the vaccine to be thrown in prison…
According to a recent report from the Telegraph, scientists have reported that COVID-19 mRNA vaccines may cause heart-related injury by provoking an aggressive immune response.
In the United Kingdom, more than 2,000 individuals were recorded as developing inflammation of the heart muscle (myocarditis) or the surrounding heart lining (pericarditis) after vaccination, with the highest incidence seen among younger males.
Data indicated that most of these cardiac cases were associated with mRNA-based vaccines, including those produced by Pfizer and Moderna.
Researchers at Stanford University have since identified a possible biological mechanism behind these reactions.
Their findings suggest that the immune system can recognize and bind to the foreign RNA introduced by the vaccine, triggering an intense immune response. In certain cases, this reaction may extend to heart tissue, leading to inflammation.
This data won't be released here in NZ by MOH or whoever. Narrative is set in stone with MSM it seems.
