Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

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.

Pyrexia and DTaP + IPV + Hib + Hepatitis B (Vaxelis)

Pyrexia has been reported 296 times in association with DTaP + IPV + Hib + Hepatitis B (Vaxelis) vaccination in VAERS. This represents 12.3% of all 2,414 reports for this vaccine.

Among these reports, 3 mentioned death (1.01%) and 19 involved hospitalization (6.4%).

Pyrexia is the #3 most frequently reported symptom for DTaP + IPV + Hib + Hepatitis B (Vaxelis) out of 306 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 296 reports of Pyrexia after DTaP + IPV + Hib + Hepatitis B (Vaxelis) vaccination may seem alarming, but context is critical.

The mortality rate of 1.01% 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 →
