WA PERTUSSIS EPIDEMIOLOLGY
WA DOH is looking at getting data on maternal Tdap utilization
Current recommendation is that women get a Tdap immunization in their third trimester with every pregnancy.
Current pilot is looking at what type of information would be available in the major EMRs used in birthing hospitals in the state. In Spokane we are looking at Valley and Deaconess
Hospitals. Goal is to get maternal Tdap information from all
birthing hospitals in WA.
RESEARCH IN WASHINGTON STATE

Historically vaccines for meningococcal disease covered 4 of the 5 strains (A, C, W135 and Y) but a vaccine covering the B strain has not been FDA approved for use in the US
Type B is responsible for roughly a third of meningococcal cases in the US and is more common with infants
In 2013-14 a large number of outbreaks of meningitis B were associated with colleges The 2013-14 outbreak at Princeton led to CDC requesting
and receiving approval from the FDA to import Bexsero to respond to the outbreak.
