we've established that in this scenario, steak is the only protein available, and while unlikely, its possible. how common would you say vaccines are that require the murder of innocent animals? how common would contracting said disease be?
That's a very peculiar scenario then.
People who are vegan choose to do so (or are raised such) while in an environment where they have access to plant-based foods that cover their dietary needs. Were someone in a scenario where they had no access to protein from plant-based foods, they'd never have been vegan in the first place.
If a vegan somehow experienced an extreme change of circumstances beyond their control where they only had access to steak for protein, they could eat the stake, since veganism is the avoidance of animal products as far as is possible, and it's not possible to live without consuming protein.
The vaccine question is really complicated as it entails lots of different confounding notions such as probability of getting a life-threatening condition versus actually certainly having them--reminder that I specifically was talking about medicine in response to carteblanche which would mean a currently existing condition, and not talking about vaccines.
To give a better answer, you'd need to give me a more specific scenario in terms of what sort of disease it'd be, and what harm to the animals it'd entail.
