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.

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 18,043 reports of Pyrexia after Hib (Pedvaxhib) vaccination may seem alarming, but context is critical.

The mortality rate of 1.59% warrants monitoring, though VAERS deaths represent temporal associations, not confirmed causal links.

Important Context

Association, not causation: These reports show Pyrexia occurred after vaccination, not that the vaccine caused it.
Background rates: Pyrexia 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 →
