Summary
Brief summary
Pregnant women and children with chronic medical conditions are at increased risk of hospitalisation, intensive care admission and death from influenza and COVID-19 infections. However, there appears to be a high level of vaccine hesitancy among women of reproductive age. We will develop "nudge" interventions to improve influenza and COVID vaccine uptake and test the effectiveness of the interventions using randomised controlled trials in

* pregnant women
* medically at risk children.
