Increasing uptake of maternal pertussis vaccinations through funded administration in community pharmacies.

Although maternal pertussis vaccination is recommended, uptake is suboptimal in New
Zealand (NZ), despite full funding in general practice and hospitals. We determined whether funding
maternal pertussis vaccination in community pharmacy increases its uptake. Pertussis vaccination
during pregnancy was compared between non-contiguous, demographically similar regions of NZ.
The pertussis vaccine was funded at pharmacies from Nov 2016 in one NZ region (Waikato), but not
in comparator regions (Northland, Hawkes Bay). Vaccinations during pregnancy were determined
from the National Immunisation Register, general practice and pharmacy claims data, and a maternity
database. Comparisons were made using adjusted odds ratios (OR) and 95% confidence intervals (CI)
for Nov 2015 to Oct 2016 versus Nov 2016 to Oct 2019. The odds of pregnancy pertussis vaccination
increased in the post-intervention versus pre-intervention period with this increase being larger
(p = 0.0014) in the intervention (35% versus 21%, OR = 2.07, 95% CI 1.89–2.27) versus the control
regions (38% versus 26%, OR = 1.67, 95% CI 1.52–1.84). Coverage was lower for M¯aori versus
non-M¯aori, but increased more for M¯aori in the intervention versus control regions (117% versus
38% increase). It was found that funding maternal pertussis vaccination in pharmacy increases
uptake, particularly for M¯aori women. Measures to increase coverage should include reducing
barriers to vaccines being offered by non-traditional providers, including pharmacies.
