Objectives: Vaccine administration where pregnant individuals receive prenatal care may increase vaccine coverage. Availability of influenza vaccine at prenatal care visits is not standard in Canada. Since the 2016-2017 influenza season, pregnant individuals can receive the influenza vaccine at point of care (POC) in an urban clinic in Calgary, Alberta. The objective of this study was to descriptively examine vaccination rates across multiple influenza seasons for a POC-vaccination in pregnancy (VIP) intervention and describe associations between influenza vaccine coverage and comorbidities and area-level socioeconomic status.
Methods: A before-and-after study design was used to examine vaccine coverage across six consecutive influenza seasons: two before (2014-2015 and 2015-2016) and four after POC-VIP implementation (2016-2017 to 2019-2020). We identified the birth cohort and measured influenza vaccine uptake using clinical and administrative databases. Influenza vaccination rates were computed and compared using Fisher's exact test with statistical significance at P value 0.05 RESULTS: A total of 4443 pregnancies were identified during the study period. The influenza vaccination rate increased in the intervention years at 40.1 per 1000 patient-weeks (P < 0.001), compared to the pre-intervention influenza seasons at 11.7 per 1000 patient-weeks. Vaccine coverage did not statistically differ between pregnancies with or without comorbidities across most seasons. Vaccine coverage decreased as material deprivation increased in pre-intervention years.
Conclusion: The vaccination rate was higher in the intervention years compared to the pre-intervention period. In this study, we applied a systematic methodology to examine vaccine coverage in pregnancy and presented a descriptive examination of a POC-VIP intervention.
Keywords: influenza; point of care; pregnancy; vaccine.
