Me getting vaccinated protects more than just me. It protects, for example, those who cannot get vaccinated by limiting the spread of a disease. Your perspective could be (perhaps slightly unfairly) summarized as 'your child has leukemia and caught a cold from me, well that's THEIR problem not mine'
I do not understand, and refuse to accept, that absurdist shift towards individualism at the expense of all others. It makes no sense, it is often willfully blind to the realities of day to day interaction...and its just mean spirited.
Watching the anti-COVID vaccine folks has helped me realize this isn't about medicine or science or understanding...its about selfishness.
