Central hypothesis: a multimodal approach is needed to enhance RSV vaccine uptake in pregnancy rather than the current standard of care that relies solely on physician recommendations at routine prenatal visits and/or mass messaging to the public. The investigators propose a pilot sequential multiple assignment randomized trial (SMART) to evaluate the effectiveness of a bundle of evidence-based and sequential strategies to test early (28-30 weeks gestation) and late (34-36 weeks gestation efficacy) to increase RSV vaccination during pregnancy.
