"To be fair" (everyone hates those words), it is entirely possible that PER DOSE Astrazenica is more dangerous than birth control re:clotting, but one is taken twice, while the other is taken twice... per day. Or some other situation like that, where rather than the truth lying between both sides, both sides are entirely accurate but arguing different points.
0.00017% sounds like a lot less than 0.01%, until you realize that after 3 years, you've taken 1000x the doses. 0.00017*1000=0.17, far, FAR greater.
But that failure rate for a one-time risk is low enough to not be a concern compared to other, more likely side effects, or unknown longer term effects.
You'd need to multiply the vaccine number by 1000 to get anywhere close to the dosing amount of birth control. You wouldn't multiply the birth control by 1000, it's ALREADY 1000 times greater.

You're reversing the calculation. People take birth control for three years. One dose per day, 365 days, three years, 1000+ doses.
And they calc it usually by "did they get one while on it?", for most such things. If they're really diligent, they'll include a baseline rate, too.
Precisely.
