What was claimed

The vaccine is worse than the disease

Our verdict

Inaccurate

The chance of harm from an infectious disease is far greater than the chance of harm from the vaccine. A person is far more likely to be seriously harmed by a disease than by a vaccine, as vaccine-preventable diseases like measles, meningitis, hepatitis B or polio can be deadly or cause severe illness and disability. Most side effects from vaccination are mild, such as soreness, swelling, or redness at the injection site, while serious side effects are rare. (Only 2 of 3 AI systems responded.)

What other AI think

The claim is contradicted by extensive evidence from major health organizations. Medical research consistently shows that the risk of harm from vaccine-preventable diseases far exceeds the risk from vaccines themselves. This is a significant factual error with potential public health consequences.

This claim may mislead readers without added context.

The statement is a broad, comparative health claim that is not supported by the totality of evidence. Vaccines for major infectious diseases overwhelmingly reduce severe illness, hospitalization, and death while serious adverse events are rare.

For approved vaccines (e.g., measles, polio, COVID-19), clinical trials and real-world studies show large reductions in severe disease, hospitalizations, and deaths, while serious vaccine harms are rare and far less common than the harms caused by the diseases themselves.
