- National surveillance data continue to show high rates of both influenza-related hospitalizations in pregnant women and pertussis-related deaths in infants aged
Why this matters
- Physicians should initiate maternal vaccination schedules early in pregnancy to improve influenza, tetanus-diphtheria-acellular pertussis (Tdap) vaccine discussion frequency.
- Physicians should consistently offer influenza, Tdap vaccines to pregnant patients, highlighting infant protection benefits.
- Pregnant women accounted for 24%-34% of 2341 reported influenza-related seasonal hospitalizations from 2010-2011 to 2017-2018.
- From 2010 to 2017: 7731 infant pertussis hospitalizations, of which 50.8% (3928) occurred in infants aged
- Internet panel survey: 53.7% (2097), 54.9% (817) of eligible pregnant women reported receipt of influenza, Tdap vaccines, respectively.
- 34.8% of women with recent live births reported receipt of both.
- 65.7%, 70.5% receiving a provider influenza or Tdap vaccination offer/referral, respectively, received either vaccine.
- Reasons for nonreceipt: ineffective (17.6%, influenza), not knowing it was needed (37.9%, Tdap), infant safety risks (15.9%, 17.1%, influenza, Tdap, respectively).
- Retrospective national surveillance and survey data analysis evaluating influenza and pertussis disease burden among pregnant women and infants, maternal influenza, and Tdap vaccination coverage.
- Funding: CDC.
- Underestimated outcomes, under-/overestimated coverage.
- Potential confounders unanalyzed.
