This guy should have been more careful. It's not as if he wasn't warned when he recieved the inocculation.
The warnings they give to these guys are very specific, and there is an excellent website with all the information. I have cardiac problems, and we had to follow some pretty strict rules after hubby had his vaccination.
It's not like they didn't know. Reactions like this are pretty rare. Knowing that they inject these guys with live virus, common sense would dictate that you either follow the after-care instructions or he should have stayed away from the house.
I just hope he didn't have any contact with other toddlers, like in day care, while he was contagious but without obvious symptoms. I know from experience that chicken pox (for example) is most contagious the day BEFORE the blisters form. I'm not sure about whatever is used in these vaccines.
I'm constantly amazed (and irritated) by the number of people who will knowingly place a sick child in a setting with other children. This especially happens at church and then the parents get mad at YOU or the nursery director for asking them to remove their sick child.
