Unveiling a New Strategy
The recent study titled “Increasing influenza vaccine uptake in children: A randomised controlled trial” sheds light on a novel approach to enhance the uptake of influenza vaccines among children in Hong Kong. This groundbreaking research offers a fresh perspective on the potential of simple intervention packages in promoting vaccine acceptance.

The Source Article's Abstract
BACKGROUND: Influenza vaccine is not included in the Hong Kong Government's universal Childhood Immunisation Programme but eligible children can receive subsidised vaccine through the private sector using the Vaccination Subsidy Scheme (VSS). This study examined whether a simple intervention package can increase influenza vaccine uptake in Hong Kong children.
METHODS: Two study samples were enrolled: families of children who had participated in a previous knowledge, attitudes and practices study; and mother-infant pairs recruited from postnatal wards. Control groups received publicly available leaflets about VSS. Intervention groups additionally received: (1) a concise information sheet about influenza and its vaccine; (2) semi-completed forms to utilise the subsidy; (3) contacts of VSS clinics that did not charge above the subsidy; and (4) text message reminders for vaccination. Enrolled mothers were contacted when children were approximately 1 and 2 years old to determine influenza vaccination status of the families and their plan to vaccinate their children. Mothers' attitudes towards influenza vaccine were assessed at enrolment and at the end of the study.
RESULTS: A total of 833 eligible mother-infant pairs were enrolled from the two samples. The intervention package improved influenza vaccine uptake by 22% at one year and 25% at two years of age. Maternal influenza vaccine uptake in intervention group was higher during this two-year period in those who had never been previously vaccinated. Mothers' self-efficacy regarding the use of influenza vaccine in her child i.e. belief and confidence in her own ability to make a good decision, was also improved with the intervention.
CONCLUSIONS: A four-component intervention package could improve influenza vaccine uptake in Hong Kong children and their mothers during the first two years of life and depending on vaccine effectiveness could potentially reduce influenza-associated hospital admissions in children below 2 years old by 13-24%.

In Hong Kong, the universal Childhood Immunisation Programme does not encompass the influenza vaccine. However, eligible children have the opportunity to receive a subsidized vaccine through the private sector, courtesy of the Vaccination Subsidy Scheme (VSS).
Intervention: A Four-Pronged Approach
The study introduced a four-component intervention package to the participants:
- A concise information sheet about influenza and its vaccine
- Semi-completed forms to utilize the subsidy
- Contacts of VSS clinics that did not charge above the subsidy
- Text message reminders for vaccination
The results were promising. The intervention package bolstered influenza vaccine uptake by 22% at one year and 25% at two years of age. Such a significant increase underscores the potential of this approach in enhancing vaccine acceptance among children and their families.
Implications for the Medical Community
This study’s findings have profound implications for the medical community. By adopting such simple yet effective intervention strategies, healthcare professionals can potentially increase vaccine uptake, thereby reducing the risk of influenza outbreaks and ensuring a healthier community.
