摘要Background: Influenza is a common contagious viral respiratory disease. Children are vulnerable to influenza as they lack prior immunity and exposure. Studies showed that influenza in childhood has remarkable socio-economic impact on children’s households as they are efficient transmitters for spreading influenza. The influenza vaccination for school children was effective in reducing the number of class cancellation days and absenteeism in the school. However, poor vaccination uptake rate among children was observed in Hong Kong. As such uptake primarily depends on parental perceptions towards children influenza vaccination, we conducted this study to understand their perceptions.

Method: A cross-sectional online survey was conducted from March 2018 to May 2018 among parents of children aged 6 months to 12 years old. The snowball sampling approach was adopted to collect responses via multiple social media platforms. The questionnaire includes socio-demographics of both parents and their children, vaccination uptake information of children in the 2017/2018 season, parental knowledge and perception towards influenza and corresponding vaccination.

Results: A total of 230 complete responses were analysed. Most respondents were mothers (80%), with mean age 35.4 years (SD=4.82), and were responsible for making the vaccination decision for children (87%) . The reported 2017/18 influenza vaccination uptake rate was 26% (59/230). Receipt of last year’s vaccination strongly predicted parental decisions (OR:19.73; 95% CI: 9.64, 42.97). Poor parental knowledge was observed: 13% (29/230) correctly indicated the period of peak flu seasons, and the time required for boosting antibody by vaccination (38/224). Children more susceptible to influenza infection (OR:4.31; 95% CI: 2.17,9.26) and suffering from more serious consequences after infection (OR: 4.73; 95% CI: 2.33,10.46) than the general public were two parental perceptions positively associated with receipt of children vaccination. On the other hand, the most common reason for non-vaccination were: children in good health condition and vaccines being ineffective or leading to adverse effects. In addition, only 24% (56/230) considered vaccination as the most effective means of protection.

Discussion: Poor knowledge of influenza (and vaccination) among parents in Hong Kong suggest more intense promotion is needed. With children susceptibility towards and consequences of influenza infection being two parental concerns in regard to receipt of children vaccination, further promotion campaign could focus on these two perception framework to boost the vaccination uptake rate. Since children’s health conditions were parental concerns, incorporating promotion with regular children check-up could probably boost uptake rate.
