The antenatal care provider’s advice to have influenza vaccine was the single most important factor associated with vaccination (OR 11.1,95% CI 7.9–15.5). Most women (63.7%) were vaccinated in general practice, 18.8% in a public hospital antenatal clinic
and 11.0% at their workplace. Wanting to protect their infant from infection (91.2%) and having the vaccine recommended by their GP (60.0%) or obstetrician (51.0%) were commonly reported reasons for vaccination; worrying about side effects was a common reason for nonvaccination.
