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 COVID-19 Vaccine

Pyrexia has been reported 144,135 times in association with COVID-19 Vaccine vaccination in VAERS. This represents 12.9% of all 1,121,388 reports for this vaccine.

Among these reports, 1,638 mentioned death (1.14%) and 12,759 involved hospitalization (8.9%).

Pyrexia is the #3 most frequently reported symptom for COVID-19 Vaccine out of 9223 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 144,135 reports of Pyrexia after COVID-19 Vaccine vaccination may seem alarming, but context is critical. With 1,121,388 total reports for this vaccine (representing many millions of doses), Pyrexia appears in only 12.9% of reports.

The mortality rate of 1.14% 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 →
