Enhancing Protection Against Influenza and COVID-19 for Pregnant Women and Medically at Risk Children

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 among pregnant women and medically at risk children and test the effectiveness of the interventions using randomised controlled trials.

Inclusion Criteria:Pregnant women (COVID RCT) - those who have received 2 or less doses of a recommended COVID-19 vaccine Pregnant women (influenza RCT) - those who have not received the influenza vaccine during pregnancy Medically at risk children (COVID RCT) - those who have received 1 or no dose of a recommended COVID-19 vaccine Medically at risk children(influenza RCT) - those who have not received the annual influenza vaccineExclusion Criteria:Pregnant women (COVID RCT) - those who have received 3 or more doses of a recommended COVID-19 vaccine Pregnant women (influenza RCT) - those who have received the influenza vaccine during pregnancy Medically at risk children (COVID RCT) - those who have received 2 or more doses of a recommended COVID-19 vaccine Medically at risk children(influenza RCT) - those who have received the annual influenza vaccine
