Comedian Heather McDonald collapsed on stage as a result of the COVID-19 vaccine.

Publisher’s rating: False

Related reporting identifies the event as comedian Heather McDonald’s collapse during a stand-up show in February 2022. It says she joked shortly beforehand, “I’m vaxxed, double vaxxed boosted.” The excerpt also reproduces claims that the collapse followed her remarks and was caused by the COVID vaccine, but it does not provide evidence establishing that causal link. The material in the excerpt is limited: it includes a report that McDonald appears in the trailer for the anti-vaccine film “Died Suddenly,” and describes the film’s framing of her collapse. It does not give medical findings or another documented explanation for why she collapsed. Thus, this supplied reporting establishes the event and the context of the vaccine-related claim, but does not, by itself, determine the cause.
