Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

Myocarditis and Smallpox (Acam2000)

Myocarditis has been reported 545 times in association with Smallpox (Acam2000) vaccination in VAERS. This represents 6.2% of all 8,768 reports for this vaccine.

Among these reports, 10 mentioned death (1.83%) and 315 involved hospitalization (57.8%).

Myocarditis is the #14 most frequently reported symptom for Smallpox (Acam2000) out of 1393 total symptoms.

Disclaimer: VAERS reports describe events that occurred after vaccination but do not establish that the vaccine caused the event. Many reported symptoms may be coincidental or related to underlying conditions.

What This Means

Seeing 545 reports of Myocarditis after Smallpox (Acam2000) vaccination may seem alarming, but context is critical.

The mortality rate of 1.83% warrants monitoring, though VAERS deaths represent temporal associations, not confirmed causal links.

Important Context

Association, not causation: These reports show Myocarditis occurred after vaccination, not that the vaccine caused it.
Background rates: Myocarditis may occur naturally at baseline rates in the population, unrelated to vaccination.
Anyone can report: VAERS accepts reports from anyone — patients, parents, healthcare providers — without requiring medical verification.
Denominator missing: VAERS counts reports, not rates per dose. Without knowing how many doses were given, raw counts can be misleading. Learn more →
