Antigens are substances that provoke some form of immune response. In people who are only mildly ill, the immune protection that can prevent a second infection may wane within a few months. Or, even worse, why are some children simply not immune at all, like those kids that have to live in clean rooms? DiGeorge is caused by a genetic problem for which there is no cure. The fact is that we are assaulted by pathogens – bacteria, viruses, amoeba, etc – every single day but do not succumb to the infectious diseases that these germs are alleged to produce. “Those people might benefit more from the vaccine than others would,” said Bill Hanage, an epidemiologist at the Harvard T.H.
