No, it's not morally equivalent, as one of these is very obviously unintentional and a result of simply living one's normal life, and the other is neither of those things.

It's also somewhat irrelevant since the vaccines do not prevent transmission. At best they lower the chance to some degree and now you're in the weeds of trying to measure something that's too multivariate to measure.

Scientists and the government were also unaware of vaccine side effects. These vaccine injuries and deaths were also unintentional.

"Living one's normal life" seems to unreasonably privilege the status quo. I am sure many drunk drivers also felt they were simply living their normal lives, before drunk driving was illegal. The definition of "normal life" changed because it needed to. When there's a global pandemic on, it needs to include vaccinations.

"Herd immunity is too multivariate to measure" seems like a very strong claim. Do you have a source for that?
