I still am not entirely following your logic in relation to giving someone polio....

I feel my responsibility to myself (and my loved ones) is to get every vaccine that is made available (and approved by the FDA and advocated by the CDC) to keep me from getting infected with something that could have been prevented. This also happens to further herd immunity, on which I also place a high value.

Nor am I disrespecting Katje's (or anyone's) decisions not to vaccinate, just expressing my personal opinion on the matter.
