the kids had 2x MMR and their immunity will be checked before they are ttc. My immunity is checked. The very few times the kids had something that could have been contagious, I called the doctor's office and got an appointment in lunch break/after hours and that is ALTHOUGH I know that it is highly unlikely that they would have had measles.
This family made the conscious decision to leave their son unvaccinated. They took him into a waiting room at their ped's office when he ran a high fever and was coughing. This about as irresponsible as it gets (and they do suffer from the knowledge that their poor choices ultimately will have killed two children).
Now they may have been particularly uninformed and thoughtless - I don't know the parents of the index case, I have just "talked" (online) to one of their victims' mum and uncle, but anyone who has read this and still leaves their children unvaccinated is knowingly turning them into potential murder weapons.
