COVID-19 vaccination in pregnancy: A quantitative and qualitative analysis of the effect of strong public health messaging in an Australian cohort.

Background: SARS-CoV-2 infection in pregnancy predisposes women and their offspring to adverse health outcomes, while internationally reported rates of vaccination uptake remain low. Our study objective was to quantify the uptake of COVID-19 vaccination in pregnant women, and to assess their attitudes toward vaccination in pregnancy with both quantitative and qualitative analyses.

Materials and methods: This is a prospective, cross-sectional survey at Australia's largest quaternary level maternity centre. A total of 351 pregnant women, at 6-42 weeks gestation receiving antenatal care at our hospital, completed an online voluntary, anonymous, 17 question survey. This was conducted during a five-week period in November to December 2021. The main outcome measures were demographic data, prior SARS-CoV-2 infection and COVID-19 vaccination status, knowledge and attitudes surrounding COVID-19 disease and vaccination in pregnancy.

Results: High rates of COVID-19 vaccination were observed in this pregnant population. Of the 351 respondents, 82% had received at least one dose of the COVID 19-vaccination. This increased compared to estimates of 15% in June 2021 which were obtained from the hospital's electronic health record.

Conclusions: Our survey demonstrates that a strong public health campaign with clear messaging regarding the beneficial effects of COVID-19 vaccination in pregnancy can lead to high vaccination uptake rates.
