BTW, OP......I don't allow any child to attend until 48 hours has passed since they were vaccinated. I do this for a number of reasons. One being that it is the riskiest time for adverse reaction. I just mention this as you mention it was passed off as a reaction to his MMR vaccine. That could not happen here because I wouldn't have allowed him into care for 48hrs so I would KNOW it wasn't from the vax.
