BACKGROUND: Vaccination during pregnancy is recommended to protect pregnant individuals and their fetus from vaccine-preventable diseases and to protect infants during the vulnerable postnatal period. However, vaccine uptake in pregnancy remains low. This study explores how pregnant, postpartum and breastfeeding individuals living in Canada prefer to communicate about vaccination during pregnancy. METHODS: We used peer-to-peer, patient-oriented research to conduct an exploratory qualitative descriptive study using focus groups and semistructured in-depth interviews to enquire about vaccination in pregnancy communication preferences, including preferred provider and communication timing. We coded deductively using direct content analysis and inductively while remaining sensitive to themes arising during the interviews. RESULTS: Fourteen individuals from diverse cultural backgrounds living in Canada who self-identified as women and either as being pregnant, recently postpartum, or breastfeeding participated. Most preferred a participatory approach to vaccine communications combined with clear guidance. A trusted relationship with their provider mattered more than the healthcare provider's profession. Participants wanted to discuss vaccines early and often to allow them time to find answers and discuss with their partners before making decisions. Participants also shared the importance of mutual respect, maintaining their autonomy and not feeling forced or coerced. CONCLUSIONS: Pregnant individuals want to play an active role in decision-making regarding vaccination during pregnancy. Their preference is to have open communication with familiar, trusted providers where they can express their questions and receive a clear recommendation which takes into consideration their unique circumstances so they can evaluate their options before making a decision.
