Reasons for use and non-use of the pertussis vaccine during pregnancy: an interview study

INTRODUCTION In New Zealand, pertussis vaccination is recommended and government-funded during every pregnancy to protect the infant after birth. However, uptake is low and needs to be increased. AIM To investigate enablers and barriers for uptake of the pertussis vaccination by pregnant women in New Zealand, and explore the acceptability of provision in pharmacies. METHODS Women with infants were recruited in selected pharmacies and interviewed using abrief structured interview. Transcripts were analysed using a framework approach. RESULTS Thirty-seven women aged 18-43 years provided data for analysis. Seventeen women reported receiving a pertussis vaccination during their pregnancy. Information from health professionals appeared important to encourage vaccination, but other sources of information (eg antenatal groups and media) were also cited. Non-vaccination arose from being unaware of the need for pertussis vaccination during pregnancy, concerns about safety, and misinformation. Participants supported pertussis vaccination in pharmacies to help access or increase the opportunity for health professionals to inform women. DISCUSSION The information received by participants affected their uptake of the pertussis vaccine during pregnancy. Education of the public and health professionals about the pertussis vaccine during pregnancy is necessary.
