Pertussis vaccination uptake in pregnancy: lessons to be learned from an integrated healthcare approach

To determine the proportion of pregnant women vaccinated with the pertussis booster in the third trimester of their pregnancy, and explore factors influencing coverage.

A clinical audit was undertaken at Rotorua hospital using electronic databases to determine pertussis immunisation among women who birthed from 25 March to 25 April, 2017 (n=111). Lead maternity carers (LMCs) were surveyed to assess knowledge of the vaccine and explore suggestions to increase vaccination coverage.

Only 44% (n=49) of women were vaccinated in 2017. Women 25 years and under, and women from Rotorua were less likely to be vaccinated. A woman not being recalled to the GP for vaccination was the biggest reason for not being vaccinated (n=27). Every woman in Taupo/Turangi was recalled in pregnancy, leading to greater vaccine uptake compared to women in Rotorua.

Overall, the proportion of pregnant women vaccinated for pertussis continue to be low with coverage being disproportionally lower for younger women. The integrated healthcare approach in Taupo/Turangi has resulted in improved vaccine uptake. Interventions that allow general practitioners, LMCs and primary health organisations to work together can improve vaccination rates of pregnant mothers in New Zealand.
