But there was one thing they couldn't have more rigor on testing - time.

I got the jab and the booster, but I think it is pretty clear the political pressure to call it good was higher than in any of those previous vaccines. The monetary pressure was probably also higher. I would not be even remotely surprised if we find it was more dangerous than most vaccines from an autoimmune standpoint simply because of the nature of the virus. I still think the risk-reward was good for almost all adults, and probably children too (my kid got theirs when it was approved), and I understand the paternalistic reasons for guilding the lily on its safety are well intentioned. But I also think it is naive to assume all that pressure had no effect.
