Well but:: Studies show: newer vaccine works well but fades over time. 1) kids who get pertussis 89% < likely to have had all 5 series dtap. Get the series 2) but the newer vaccine does not stay protective as long and must be boosted for certain: w/in the 1st years of series immunity 95%. By age 8-10 years it is 70%. In calif in 2010: 3% cases in 4 year olds. 31% cases were in 10 year olds. Stay boosted.
