A major new study is raising the alarm about the deadly long-term risks now faced by people who received Covid mRNA “vaccines.”
The massive new study tracked the outcomes of people in Australia for 18 months after they received their injections.
The team of researchers, led by Dr. Lucy Deng from the National Centre for Immunisation Research and Surveillance (NCIRS), sought to analyze the long-term risks from potentially fatal conditions caused by mRNA “vaccines.”
Alarmingly, the scientists found that patients were still suffering from a deadly heart condition at the end of the 18-month study, indicating that they could be carrying a ticking time bomb for many years to come.
The study was published in the prestigious Nature’s July 2025 Vaccines medical journal.
The discovery has raised alarming questions about the long-term health risks of the Covid mRNA “vaccines,” particularly for those who suffer from myocarditis, a potentially life-threatening inflammation of the heart muscle.
Often referred to as a “silent killer,” myocarditis restricts the heart’s ability to pump blood.
The dangerous condition can, without warning, trigger a blood clot, stroke, or cardiac arrest, ultimately leading to sudden death.
According to the research, 35% of individuals diagnosed with myocarditis following the Pfizer-BioNTech or Moderna Covid mRNA injections experienced lingering symptoms 12 to 18 months after their initial diagnosis.
This long-term data reinforces growing concerns among a growing number of experts and advocates of medical transparency about the risks that have been downplayed in earlier stages of the “vaccination” campaign.
The study tracked 256 individuals who had been diagnosed with myocarditis after receiving the mRNA “vaccines.”
The findings indicate that a significant portion of patients continue to experience damaged heart tissue long after the acute phase of the illness has passed.
This is particularly concerning for those who were told the benefits of the mRNA shots outweighed any risks.
The study tracked individuals diagnosed with myocarditis in Australia between April 2021 and July 2022.
The cohort was carefully monitored through national adverse event reporting systems, with clinical confirmation of myocarditis, structured interviews, and standardized health surveys at both 3-6 months and 12-18 months after their diagnosis.
This prospective study design aimed to provide an in-depth look at the long-term impacts of myocarditis linked to the mRNA injections.
The results are deeply concerning for those who have been advocating for a more cautious, transparent approach to “vaccine” safety.
The results paint a troubling picture of the persistent and potentially devastating effects of myocarditis, especially for younger, male patients.
While the majority of myocarditis cases were mild (with a median hospital stay of only two days and no ICU admissions), 35% of patients still reported persistent symptoms 12 to 18 months after their initial diagnosis.
These ongoing symptoms, primarily chest pain, palpitations, and fatigue, highlight the fact that myocarditis is not just a temporary side effect but could lead to long-term health complications.
Notably, 13% of the patients who had myocarditis were still on medication to manage their symptoms, and 8% reported self-imposed restrictions on exercise.
Even more concerning, 5.6% of patients required hospitalization again due to the lingering effects of myocarditis.
These statistics underscore the reality that myocarditis can be a “silent killer,” with long-term risks that could increase the likelihood of sudden death or other severe complications.
This should raise red flags for anyone advocating for the continued use of mRNA shots without proper acknowledgment of the risks involved, particularly for young, healthy individuals who were led to believe the “vaccines” were safe and without consequence.
One of the more concerning aspects of the study was that nearly 23% of patients, despite experiencing myocarditis, chose to pursue revaccination, sometimes with another mRNA jab.
The decision to push additional doses despite the known risks raises serious questions about the long-term safety of continuing to administer mRNA “vaccines” to people who have already suffered from a significant adverse reaction.
This is especially troubling for advocates of medical transparency, who argue that there needs to be much clearer information about the potential risks of revaccination, particularly for those who have already been affected by myocarditis.
Just as important is the need for more transparent data about the ongoing health impacts faced by those who choose to undergo further vaccinations.
This study is an important step toward understanding the long-term risks associated with mRNA vaccines, but it also highlights the glaring gaps in research that still need to be addressed.
The researchers emphasize the need for further exploration into the mechanisms behind persistent symptoms and for more targeted monitoring and risk stratification for those who are most at risk.
The call for medical transparency in the wake of these findings is clear.
As vaccine mandates and boosters continue to be pushed by governments and health authorities, it is critical that patients are fully informed about the long-term risks associated with mRNA vaccines, including the risk of myocarditis and other potential heart complications.
Furthermore, as new data surfaces, health officials must engage in a more honest conversation about the risks and the necessity of monitoring individuals who experience adverse reactions.
This study adds to the growing body of evidence that mRNA vaccines can have serious long-term consequences for some individuals, particularly in terms of cardiovascular health.
With 35% of patients suffering from lingering symptoms of myocarditis 12-18 months after vaccination, it’s clear that the full scope of risks associated with the vaccines has not been adequately communicated to the public.
For those advocating for transparency in medical practices, this study is a wake-up call.
The time has come for a more honest and open conversation about the potential dangers of mRNA “vaccines” and the need for continued research, especially when it comes to young people and vulnerable populations.
Until then, individuals must be fully aware of the risks they face when making decisions about vaccination, and the medical community must step up its commitment to transparency and full disclosure.
