Veria - Claim Fact Check

Claim: COVID‑19 vaccines increase the risk of depression by 530 times compared with flu shots.

No published study reports a 530-fold increase in depression risk after COVID-19 vaccination relative to flu shots; the figure does not appear in any peer-reviewed or pre-print analysis of VAERS or other safety databases¹.
The claim appears to grossly distort or fabricate a finding from a 2025 VAERS-based study that actually calculated proportional reporting ratios (PRRs) of 115 for general psychiatric illness, 118 for cognitive impairment, and 80.1 for suicide/homicide—not 530 for depression²¹.
A PRR measures disproportionality in spontaneous reports, not actual incidence, risk, or causation. The CDC and FDA explicitly state that raw VAERS report counts cannot be interpreted as evidence of a causal association, existence, severity, frequency, or rates of problems associated with vaccines³.
Fact-checkers have repeatedly debunked similar claims (e.g., 50× adverse effects, 300–900× death reports) that compare raw VAERS counts between COVID-19 and flu vaccines, because the vaccines differ vastly in doses administered, public awareness, media attention, and reporting behavior⁴⁵.
Large-scale epidemiological evidence contradicts the claim. A UK cohort study of 18 million individuals found depression risk after COVID-19 infection was roughly twice as high in unvaccinated people compared with vaccinated individuals⁶. Another major study found post-COVID depression incidence was only 1.16 times higher in vaccinated individuals versus 1.79 in unvaccinated individuals, showing vaccination attenuates rather than increases depression risk⁷.
Harvard Medical School researchers and experts state: “There is no evidence that vaccination causes depression and suicidality”⁶.
