Summary
Brief summary
Seasonal influenza infection is a significant cause of morbidity and mortality which can be prevented by vaccination. Notably, pregnant women and babies under 6 months are at significant risk of hospitalisation and adverse health outcomes if infected with influenza. In a retrospective audit, seasonal influenza vaccination rates in pregnant women at the Centenary Hospital for Women and Children at the Canberra Hospital were found to have increased from 35% in 2017 to 79.8% in 2017 with the introduction of a mandatory field in an electronic health record. This study aims to investigate compliance of pregnant women with seasonal influenza vaccination rates at the Centenary Hospital for Women and Children during the Covid-19 pandemic using a follow-up audit.
