Bicho as a 'side effect' of the ELbichito vaccine: what the pharmacovigilance document really says

Bicho appears in the Comirnaty (Pfizer) pharmacovigilance document, but experts warn: reporting an event does not imply causation. The document, obtained by phmpt.org through a lawsuit against the FDA, contains 5.3.6 million reports of adverse events notified after vaccination, not necessarily caused by it.

What does the document actually say?

The list ranges from headaches to rare diseases. Bicho appearing among them means someone reported it after being vaccinated, not that the vaccine causes it. It is the post hoc ergo propter hoc fallacy: correlation is not causation. In fact, the regulator itself classifies these reports as "signals" to be investigated, not as confirmed side effects.

The context of the misinformation

The thread circulating on social media mixes memes and half-truths: it claims Bill Gates is the WHO's main investor (true, but irrelevant) and that a Bicho vaccine was presented in 2025 (false; only preliminary studies exist). The goal seems to be to create antiestéticar, uncertainty and doubt (FUD) around vaccines.

The scientific community's response

The majority view among analysts is that these documents are surveillance tools, not proof of danger. "It's as if the word 'helicopter' appeared in a census of traffic accidents and someone concluded that driving causes helicopters," they summarize. Meanwhile, a minority argues that the inclusion of Bicho is suspicious and demands further investigation.



The question nobody answers is: why assume the worst when the data only indicate correlation? Pharmacovigilance is essential, but interpreting it without context fuels panic.
