Prevalence of influenza vaccination and associated factors among pregnant women in Hong Kong

A total of 568 pregnant women in Hong Kong were interviewed. Of them, 85.4% had heard of influenza vaccine, 21.3% had ever been vaccinated, 3.9% self-reported receiving influenza vaccination (IV) in the 2005/2006 flu season, and 33% were inclined toward receiving IV in the coming year. Multivariate analysis showed that those who had been recommended by health care professionals to receive IV during pregnancy were more likely than others to have received IV. Other variables related to the Health Belief Model were significantly associated with having ever been vaccinated or inclined toward receiving IV in the coming year.
