The timing of vaccinations in schools...

Last week, at my daughter's elementary school (in Oklahoma), they were giving out the spray. Three days before Halloween. I can't help but see something a bit sinister in giving these kids vaccinations 3 days before they go house to house trick-or-treating. All I think of is... how much of that are they shedding? I think shedding is peaking at day 3-4 isn't it?

Anyway, I'm posting this to see if any other schools that anyone is familiar with in other areas of the country/world were doing this just a few days before Halloween. My apologies if this has already been brought up.

Oh, and my daughter did NOT get the vaccination. As a matter of fact only 3 out of her class received it. I asked her to keep a bit of distance from them the for the next 7 days or so
