Where Chris decides not vaccine his children it seems he’s making the decision on an individual level. It can be argued that not vaccinating in a community that does is the best decision, freeriding the benefits of ‘herd immunity’. However, for a whole community it might be best to vaccinate, reducing the incidence of serious childhood diseases.
Yes, I agree that considering the community you’re in should also be a factor in the decision. But I think it is a decision that people need to make for themselves. I don’t have kids yet, so I have no idea what I’ll do, but it’s definitely not something I’ll take lightly.
