1/ Through Dec. 22, with fewer than 1 million doses of the #Covid vaccine given, @cdcgov's vaccine injury reporting system received 307 reports of ER visits and 17 "life threatening" events.

Per dose, that's roughly 50 times the rate of adverse events from the flu vaccine...

2/ In 2019-2020, about 175 million flu vaccine doses were given. 1220 ER visits and 73 "life threatening" events were reported. The data is on the CDC VAERS Website.

Caveats: physicians et al may be more diligent about reporting #Covid vaccine events, since the vaccine is new...

3/ And the data is theoretically updated through Friday Jan. 1, which would be a much higher denominator. However, I believe it is correct to use Dec. 22 as the last date for Covid adverse events because I cannot find any later reports in the system...

4/ Plus, the first Covid vaccine doses have mostly been given to healthy people in settings where problems can be quickly treated. These problems are occurring BEFORE the rollout to older, less healthy people - and before the 2nd dose, which is known to be far more dangerous...

5/ And this merely confirms what the clinical trials showed (in general, though not always, clinical trials tend to UNDERSTATE real world problems and OVERSTATE efficacy, because any smart drug company will try to bias the trials in its favor).

The data is here, and fairly straightforward to query.
