DS1, partially vaxed, has had rotavirus illness and chicken pox illness. Had one chicken pox vaccine but still got the wild virus, and a pretty decent case. Did not have the rotavirus vaccine.
DS2, unvaxed, has had rotavirus, chicken pox, and possibly rubella. He also had a severe invasiv non-typeable haemophilus influenzae infection, I list this one because NTHi infections have increased since HiB vaccine was introduced (which protects again haemophilus influenzae type B only) So he was a victim of serotype replacement.
DS3, unvaxed, no illnesses yet.
Now, ask me about the illnesses they've got that there are NO vaccines for...strep, pneumonia, lots of pink eye, about a dozen run of the mill viral illnesses...no one wants to know about how many kids get illnesses until a vaccine is available for it. I find that interesting.
