1/ @cdcgov has released its updated batch of reported Covid vaccine side effect data, through Jan. 8, when roughly 6.6 million doses had been administered. And it is... not good.

Reported deaths per dose are now running at 85x per dose of flu vaccine, and ER trips at 35x...

2/ These figures likely are underestimates for several reasons. The number of vaccinations is rising so quickly reports will lag (I use the last-day number of shots given as the denominator). For example, reported deaths rise 5x week over week, while vaccinations rose only 65%...

3/ Unlike other countries, the US has prioritized health care workers, who are younger; the Norwegian data suggests deaths are much, much more likely to follow vaccinations in the elderly...

4/ This is nearly all the first dose, and the second dose has side effects at 3-10x the first. And this is mainly the @Pfizer shot; the @moderna_tx shot has more side effects.
