Three quick points.
1. Anecdotal evidence
2. Correlation is not causation
3. From reputable science journal Nature posted five days ago:
"The mRNA vaccine made by Pfizer in New York City and BioNTech in Mainz, Germany, is associated with a rate of five cases of severe allergic reaction per million doses, and the one made by Moderna in Cambridge, Massachusetts, is associated with a rate three cases per million doses. Those affected seem to be mainly women and people with a history of allergies."
