Background: Pregnant women should receive two vaccines during pregnancy due to\nmaternal-foetal complications and risks as well as the influenza and pertussis vaccinations. The goal\nwas to evaluate vaccination coverage against influenza and pertussis in pregnant women, following\nmidwife professional advice during the pregnancy follow-up; Methods: Prospective cohort study of\n1017 pregnancies during the vaccination campaign in 2015-2016. To estimate the degree of consistency\nbetween the coverage declared by mothers and that registered in the Nominal Vaccination Registry\n(NVR), we used the Cohenâ??s kappa index (k); Results: 95.4% were registered in the NVR. Vaccination\ncoverage recorded against influenza was 64.2% (95% CI: 61.2-67.2), and 89.8% (95% CI: 87.9-91.7)\nagainst pertussis. The coverage of the pregnant women interviewed was 61.7% (95% CI: 58.1-67.3))\nfor influenza and 92.3% (95% CI: 91.4-95.3) for pertussis. Subsequent interviews of 67.2% of the\nwomen produced a kappa agreement index between the data obtained from interviews and those\nrecorded in the NVR of 0.974 (IC95%: 98.0-99.6) for influenza, and 0.921 (IC95%: 98.1-99.7) for\npertussis. The women identified midwives as the main source of vaccination information and advice\n88.4% (IC95%: 85.8-90.9); Conclusions: The NVR is an effective platform for estimating immunisation\ncoverage in pregnant women. The degree of agreement between declared vaccinations and registered\nvaccinations was high for both vaccines.
