Promotion and COVID-19 lockdown increase uptake of funded maternal pertussis vaccination in pharmacy: A mixed methods study.

Abstract

Pertussis vaccination is recommended during pregnancy to protect the baby. Pertussis vaccination was initially free to pregnant people through general practice and hospitals in New Zealand, but uptake was suboptimal. In one district funding of maternal pertussis vaccination was widened to community pharmacies in 2016. Eighteen months later promotion to pharmacies, midwives and pregnant people took place. In 2020 and 2021, COVID-19 lockdowns occurred.AimTo explore the effects of promotion and COVID-19 lockdowns on uptake of funded maternal pertussis vaccination in pharmacy, and awareness, use and opinions of promotional elements.MethodsFive years of pharmacy claims data were analysed and 12 pharmacists, 18 people eligible/recently eligible for maternal pertussis vaccination and 11 midwives were interviewed.ResultsProvision of maternal pertussis vaccination increased during and after promotion. Qualitative data showed that pharmacists valued phone calls with information about maternal pertussis vaccination and recommendations for increasing uptake. Prompted by these calls, some pharmacists contacted midwives to inform them of funded maternal pertussis vaccination in the pharmacy (which midwives appreciated) and recommended pertussis vaccination to pregnant clients. Pharmacy staff reportedly were motivated to recommend this vaccination by being informed about it and having posters displayed in the pharmacy. Pregnant people valued healthcare professionals' conversations about maternal pertussis vaccination, but appeared to be uninfluenced by posters and promotional social media posts about this vaccination. During COVID-19, maternal pertussis uptake in pharmacies increased 31% March to May 2020 (before and during the first COVID-19 lockdown) versus the same time the previous year, then declined.ConclusionPromotion appeared to have a sustained effect on uptake of maternal pertussis vaccination in pharmacies. Pregnant people were most influenced by discussions with healthcare professionals. Pharmacists and pharmacy staff increased proactivity with maternal vaccinations after promotion to them. Promotion may need to be repeated over time.
