A leading American epidemiologist is warning that COVID-19 mRNA “vaccines” are responsible for igniting a global surge in chronic disease.
The warning was issued by renowned McCullough Foundation epidemiologist Nicolas Hulscher, MPH.
According to Hulscher, Covid mRNA injections have triggered a “chronic disease epidemic” around the world.
He notes that a “toxic mix of contaminated food and water, childhood hyper-vaccination, and behavioral risks such as smoking, obesity, and poor diet” have long driven chronic disease.
However, he argues that Covid mRNA “vaccines” have caused the issue to erupt.
Hulscher warns that mRNA injections have quickly become a leading cause of chronic disease due to their “severity, scale, and preventability.”
Post-Covid Vaccine Syndrome (PCVS) refers to a prolonged, multi-system illness.
PCVS emerges in people after they’ve received an mRNA “vaccine,” such as a Pfizer or Moderna Covid shot.
It is characterized by persistent symptoms such as fatigue, chest pain, brain fog, palpitations, and neurological or autoimmune dysfunction, lasting for months, years, or even indefiniately.
PCVS has been reported in 64.6% of vaccinated individuals for at least one year following injection, a recent study found.
This figure increases to 83.9% among those who received “booster” doses.
Among adolescents, Covid “vaccination” has been associated with a 20% increase in emergency room visits, as Slay News recently reported.
A 17% rise in doctor visits was also recorded in 12-18-year-olds in the months after injection.
The findings indicate a measurable uptick in healthcare utilization due to PCVS.
A likely mechanistic explanation involves persistent production of toxic spike protein within vital organs, lasting for years, another study found.
This is supported by findings of persistent spike protein detection in 92% of PCVS patients for months after injection, suggesting a durable post-vaccination pathological state.
Collectively, these data point to a sustained post-vaccine illness syndrome that is contributing significantly to the growing burden of chronic disease across all age groups.
Removing Covid mRNA “vaccines” from the market would eliminate a major, preventable driver of the current chronic disease epidemic.
Hulscher is not the only expert sounding the alarm about the long-term impact of the injections, however.
As Slay News previosuly reported, a world-renowned toxicologist has warned that millions of people who received Covid mRNA “vaccines” have been impacted by a devastating injury, including himself.
The chilling warning was issued by the associate professor of pharmacology and toxicology at the University of Western Australia, Dr. Phil Burcham.
In a blistering critique published in the May 2025 edition of the journal Quadrant, Burcham raises urgent questions about the chemical design and safety testing of Covid mRNA “vaccines.”
Drawing upon firsthand injury experience, insider pharmaceutical literature, and decades of toxicological science, Burcham alleges that the deployment of mRNA-LNP technologies ignored well-known formulation risks.
The Covid mRNA injections also exposed patients to unvalidated toxic excipients and sidestepped rigorous preclinical evaluation, he argues.
The top professor notes that his own debilitating trigeminal nerve injury was caused by a Covid mRNA “vaccine.”
