So far, 341 million covid vaccine injections have been given in this country.
Using CDC figures, there have been about 3.5 million severe reactions to these vaccines. For the most part, these were anaphylaxis. Nearly all other reactions were termed either mild or moderate and included things like injection site pain, headache, fatigue and nausea. Severe reactions occurred in about ONE PERCENT of the injections.
Another medicine also has an adverse reaction frequency of about ONE PERCENT: aspirin!
The majority of this information came from an NIH website, PubMed.gov. I did do the math and the 3.5 million figure for anaphylaxis is an average. The NIH put the reaction frequency at between 2 and 5 million.

(34,195 posts)From the CDC report ...
"During December 1423, 2020, monitoring by the Vaccine Adverse Event Reporting System detected 21 cases of anaphylaxis after administration of a reported 1,893,360 first doses of the Pfizer-BioNTech COVID-19 vaccine (11.1 cases per million doses); 71% of these occurred within 15 minutes of vaccination."

11.1 cases (of anaphylaxis) per million doses
Using the figure of 341 million covid vaccine injections given
11.1 cases (of anaphylaxis) per million doses times 341 million covid vaccine injections given
11.1 X 341
equals 3,785.1 reactions of anaphylaxis.
Not the 3.5 million severe reactions you posted.

(15,124 posts)the 2 to 5 million case range I read on line, not the product of my math.
I'd be happy to use your figure.
It was difficult to find many general statistics, i.e., not just numbers for Pfizer or Moderna or J and J. I welcome any corrections to the statistics I did find.

(232 posts)Per the CDC website:
"Anaphylaxis after COVID-19 vaccination is rare and has occurred in approximately 2 to 5 people per million vaccinated in the United States."
The average of those rates would be 3.5 people per million vaccinated. That's a rate of 0.0000035, or 0.00035 %. Nothing anywhere near aspirin, if the latter really is 1%
Somewhere around 342 million vaccines have been given in the US, so far (163 million people fully vaccinated). Even if that 3.5-per-million people number were really 3.5 per million doses administered (which would be worse), we're talking about 342,000,000 X 0.0000035 = 1197 anaphylaxis events, total - thousands of times less frequent than your original post's rate.
