We never enforced vaxes with family until child 3 as there was a WC outbreak. I got mine in hospital, DH has his, our kids are up to date. We told DH's mother she had to get the vax and she complained but got it. DH's SF refused.... and thus didn't see DS2 until his second lot of WC shots (he's not an attentive grandfather in the least anyway so our kids didn't really miss out).

We don't bunker down for months, but if there is an outbreak, yes we are careful.
