There is a certain feeling now days that young women, who had MMR as
child, do not pass as much immunity on to their newborns so babies need
their MMR at 1 year of age now, not 15 mo. They also need a booster
between ages 4-6.

immunities for, but I'm not sure about that. Last winter I had a 6 week
old in my practice with varicella, caught from a sib. Sincerely, Pat in
