NO

An anti-vaccine activist's essay is not a report on a clinical or lab study with reproducible experimental methods.

Also, the maker of the vaccine says prion disease -- a neurodegenerative disease -- has never been shown in a lab or clinical study to be a risk of Pfizer's vaccine.

The article's author operates a website that appears to discourage vaccination and he has elsewhere proposed certain vaccines cause diabetes.

A spokesperson for Pfizer told Lead Stories, "There is no evidence to suggest the COVID-19 vaccine causes prion disease." She cited the clinical trials conducted on tens of thousands of participants in studies the FDA relied on in granting approval to Pfizer's vaccine. Documentation of the research and trials is in a 92-page briefing document Pfizer scientists submitted to the FDA in December 2020.
