Getting vaccinated is to disease what military service is to enemies who would do us harm.
And those few who abstain from vaccinations are like draft dodgers... They receive the full benefits of vaccination... because the vast majority who are vaccinated keep these diseases in check.
I was under the impression that only unvaccinated people would catch the disease but you're telling us that they also receive FULL benefits from not being vaccinated? This sounds good to me, full benefits with no risk.
