We have two ethics systems:

The first we apply to healthcare and government, and it’s best sunned up by Micheal Scott “Don’t ever, for any reason, do anything to anyone, for any reason, ever, no matter what. No matter… where. Or who, or who you are with, or, or where you are going, or… or where you’ve been… ever. For any reason, whatsoever.”,

The second is applied to private industry, and it’s best summed up by “innocent, until proven guilty”.

And that’s why we let private industry roll along with whatever they want, until we can definitively prove harm, but society found it unreasonable to ask people to vaccinate because there was a minute chance of rare side effects less bad than the disease it was for.
