Disparities in parental awareness of children's seasonal influenza vaccination recommendations and influencers of vaccination

OBJECTIVE: To determine parental awareness of influenza vaccination recommendations for children and explore associations with awareness. DESIGN: Cross-sectional survey. SETTING/PARTICIPANTS: South Australian parents with a telephone listing in the Electronic White Pages were randomly selected. METHODS: Participants were interviewed using Computer Assisted Telephone Interviewing (CATI) during May-July 2016. Univariable and multivariable analyses explored characteristics associated with awareness; with the survey data weighted to reflect the population of SA and the probability of selection within a household. RESULTS: Of 539 parents, 33% were aware of the recommendation that all children (<5 years) should receive the influenza vaccine annually with 51.9% aware that children with special risk medical conditions (SRMC) should also receive the vaccine annually. Characteristics strongly associated with parental awareness of the recommendation for children aged < 5 years were knowledge of recommendation for children with a SRMC (adjusted Odds Ratio [aOR] 10.46, CI 4.44-24.63) or living in a metropolitan area (aOR 2.91, CI 1.19-7.09). There was lack of awareness in those not working (aOR 0.13, CI 0.04-0.47), with trade level education (compared with high school) (aOR 0.25 CI, 0.09-0.71) and in those born in the UK or Ireland (aOR 0.19, CI 0.04-0.85). Awareness of the recommendation for children with SRMC to receive the vaccine was strongly associated with knowledge of the influenza recommendation for children <5 years (aOR 10.22, CI 4.39-23.77) or not being born in Australia [UK/ Ireland (aOR 7.63, CI 1.86-31.31); other (aOR 3.93, CI 0.94-16.42)]. The most influential cues to future receipt were a general practitioner (GP) recommendation (63.8%) and providing influenza vaccine free for all children (37.6%). More parents who delayed or excluded vaccines believed that their children's vaccinations (in general) were unnecessary, as other children were vaccinated (42.8%) compared to those with no or minor concerns (11.1%) (p
