Antivax types are all anti pushing vaccine on to people but if they don't want to get vaccinated then it still won't affect vaccinated folks. From my rough understanding, getting vaccinated keeps you alive or get less severe symptoms, but you can still pass it on.

So if antivax people don't get it, then why not just let them die?

Edit: guys, I'm not antivax, I just don't understand how herd immunity works.

Lack of herd immunity doesn't make a vaccinated person unvaccinated. It just means the pathogen has enough population left to sustain itself.

That’s correct, but I wasn’t implying the opposite; I hope my comment doesn’t read that way.

A fraction of the vaccinated population will not have 100% immunity. Even among healthy, non-immunocompromised people vaccines generally don’t have a 100% efficacy. For example, annual flu vaccines vary in efficacy, but are often around 50%.

As I said in my comment, herd immunity is a form of indirect protection. Keeping a disease from being able to spread prevents people from being exposed at all, regardless of their immunity status. If enough people are unvaccinated and there is no herd immunity, then that increases the risk for the whole population - even those who were vaccinated since generally that doesn’t guarantee immunity.

There are certainly arguments to be made about bodily autonomy and weighing individual rights against those of society. However, the idea that “the decision to not be vaccinated is an individual choice that doesn’t harm others” is incorrect, and therefore not a great argument against vaccine mandates.
