Your source is VAERS? Seriously? VAERS is the Wikipedia of vaccine reporting: literally anyone can submit reports. Literally. They accept reports from any individual on Earth through their website. The form to submit reports is
right here. You can go there right now and submit reports for any vaccine and any symptom. You can claim the smallpox vaccine caused death. Nobody's gotten it in decades, but you can submit the report right there. There's no verification of any information. Captain Picard of the starship Enterprise can submit a report saying the Pfizer COVID-19 vaccine killed Lieutenant Commander Data.
Let's see if they have any disclaimers on the VAERS website
I thought you had real data from somewhere. Like this link from January 6th which states in part that "No deaths from anaphylaxis were reported after receipt of Pfizer-BioNTech COVID-19 vaccine."
Directly from the link you posted;
“During December 14–23, 2020, monitoring by the Vaccine Adverse Event Reporting System [VAERS} detected 21 cases of anaphylaxis”
I ran a report and VAERS says;
ANAPHYLACTIC REACTION 30
ANAPHYLACTIC SHOCK 1
Pretty close.
