Reasons
-time off work for all, especially if caught one after the other would be hugely more than the cost of the jab, no other childcare at all apart from nursery and ft working parents
-they have my skin which scars so easily, might avoid some facial scars if they have it badly
-I haven't had cp (though have worked for over 10 yrs with small kids so wondering if immune some how)
-none of grandparents (or a substantial part of village back home) have had it and we fly to see they a few times a year, really don't want to feel the wrath of bringing it to elderly in the village! Of course this would have to be unlucky timing.
None of these reasons are hugely important so if there's a valid reason medically not to vaccinate I wouldn't, but if it's safe it seems it would make sense for us. I know I'd pay, but it's cheaper than not working.
