I am not buying the 3/1000 figure.
I in addition to mine, I know 17 unvaxxed kids if we are talking kids I see regularly, and 36 if we include kids I have not seen in a while.
I do know that birds of a feather flock together - so I might know more by virtue of who I choose to hang out with, etc…but this only counts for about 50% of the above figure. The other 50% I met at the library or swimming pool, hardly the exclusive domain of crunchy types.
I do not live in an area with a high unvaxxed rate.
