People were dropping like flies from covid clots well before there were any vaccines. It’s a shared symptom.
That’s amazing because I had COVID 2 weeks Dec ‘20, and I have high risk for clots.
I had a PE back in ‘13 due to surgery (possibly augmented by BCP usage),
I was off Tamixifen at the time concerned about side effects; it had been about 5 months since that and the counteracting baby aspirin I take because of my risk.
But anyway, no clots from that time.
