Influenza and pertussis (whooping cough) vaccinations are recommended for pregnant women in New Zealand because Influenza infection during pregnancy is associated with severe disease in the mother and poorer outcomes in babies (e.g. premature birth). Immunising pregnant women creates antibodies against infection that are passed to the fetus and protects the baby against disease in the first few months of life. However, Māori and Pacific women have lower rates of immunisation during pregnancy, especially in areas of high deprivation. The aim of this research is to understand what information Māori and Pacific women need to know to encourage vaccination during pregnancy, and how this information should be delivered.
