The argument has never been that it's only ok for humans to live if we do zero harm. It's obvious that we can't do that. And that's fine. Human life is worth much more than anything else for us humans, so eating something to survive is necessary and ethical. Same logic applies also to vaccines that need animal products in production. I would prefer if they wouldn't, but I'm not judging anyone for taking it.
