I don't understand how vaccinated people can complain about unvaccinated children as a health hazard.
Whatever disease in question is only going to affect those who are not vaccinated. Yes it is tragic if a disease can spread to 100 unvaccinated children (rather that 0 vaccinated ones).. but havn't their parents already come to terms with that risk? It's not like the vaccinated children are in danger.
Right? :/
Not quite. This overlooks two things.
First, many vaccines are not 100% effective. Thus for some diseases there is still some risk to vaccinated persons, even though it is much *less* than if they were unvaccinated. Especially for people who, though vaccinated, have immune problems for whatever reason (medical condition, age, etc)
And secondly, not everyone is voluntarily unvaccinated. In reality quite a lot of people are unvaccinated NOT as a choice but because either they have a medical reason or because (especially in these days of widespread global immigration) it was not available to them; not to mention infants who their parents might want them to *get* vaccinated but they can't be *yet* (or have been vaccinated but not yet developed strong response to it).
Also, it overlooks the fact that vaccinated people may not be
solely self-interested

and may be concerned about the possibility of a big outbreak of <whatever> even if many of those people chose to accept that risk. It can be a significant disruption to society, and significant expense, not to mention many of us do not like to see people suffer or die; so I think it is not unreasonable for people who themselves are vaccinated to still have concerns in that regard
There is also the "flip side" so to speak, but for the sake of brevity I am sticking to just responding to your particular concern.
