When there is a problem with car manufacturing, there is a recall and life goes on. When there is a problem with vaccine manufacturing, there must be a conspiracy.
The Ford Pinto had a serious safety issue where rear-ending it would lock the doors and explode. They knew about the issue but did not recall it because the cost-benefit analysis told them not-recalling was the most profitable move
So, car manufacturers weren't exactly indemnified, but the costs of doing wrong continue not to be great enough to matter.
