What was claimed

The vertigo I got after the 2nd covid vaccine shot was actually caused by a small stroke due to the vaccine. The poison they injected into us was very dangerous.

Our verdict

Inaccurate

The sources show vertigo can occur after vaccination, but they do not establish that this specific vertigo episode was caused by a stroke. Reviews also report no clear evidence of increased cerebrovascular events after COVID-19 mRNA vaccines overall. This is an unsupported and inflammatory characterization. Public health sources describe COVID-19 vaccines as generally safe, with serious adverse events being rare. (Only 1 of 3 AI systems responded.)

Detailed Analysis

The response makes a medical diagnosis and causal claim that is not supported by the evidence provided. Vertigo after COVID-19 vaccination has been reported, but the sources do not show that it was “actually caused by a small stroke due to the vaccine” in this case, and major reviews note no clear increase in neurological disorders or ischemic stroke after mRNA vaccination overall.[1] [6] [16] The phrase “poison they injected into us” is also unsupported and is misleading, because public health sources describe the vaccines as generally safe and note that serious neurologic events are rare.[1] [12]

Some case reports and rare stroke reports exist after vaccination, but case reports do not prove causation for an individual patient. The broader evidence cited here does not support a general causal claim, and major sources note no clear increase in stroke risk after mRNA vaccination.[1] [12] [16]
