Pregnant women are at disproportionate risk of harm from contracting COVID‐19, but pregnant women in regional Australia have been less likely to be vaccinated than their non‐pregnant counterparts. This longitudinal research drew from social representations theory to investigate emerging social knowledge associated with the COVID‐19 virus and COVID‐19 vaccination concerning women and pregnancy in regional Australia: One wave of data collected at the start of the COVID‐19 vaccination rollout in June–August 2021 and another wave in January–February 2022. An online survey comprised risk and benefit scales and one of two‐word association tasks completed by 304 participants in Wave One (Mage = 38.75, SD = 12.63) and 20 women in Wave Two (Mage = 40.00, SD = 11.32). Mean scale scores suggest women considering pregnancy and pregnant women perceived themselves as at disproportionate risk of COVID‐19 and the AstraZeneca vaccine. Multidimensional Scaling (MDS) and Hierarchical Cluster Analysis (HCA) suggested a negative, emerging representational field associated with COVID‐19 vaccination. MDS, HCA and thematic analysis suggested emerging contradiction in women's social knowledge of women, pregnancy and COVID‐19 vaccination in Waves One and Two. These findings reflect how pregnant women navigated a rapidly evolving context of COVID‐19 and vaccination when vaccines became available.
