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