Abstract
Purpose: To examine the effectiveness of a 3-month WhatsApp-based multi-component health education programme in promoting COVID-19 vaccine uptake among Hong Kong community residents.
Methods: A single-arm pre-post quasi-experimental study was developed (ethical No.: HSEARS20210809004). Adults who were eligible for receiving at least one new dose of COVID-19 vaccine were recruited. An intervention package, which was developed based on PROCEDE-PROCEED model, was delivered to the participants through WhatsApp by research assistants during 3-month intervention period. The package contained 3 components, including: (1) 13 health education videos involving reasons for receiving COVID-19 vaccine, effectiveness, safety and side-effect of COVID-19 vaccine, vaccination services in Hong Kong; (2) message reminder for COVID-19 vaccine uptake three times a week; and (3) vaccine booking service. Vaccination rate was calculated by the number of participants who received new dose divided by the number of participants retaining in the 3rd month.
Results: In total 50 participants were recruited. The majority of them were female (96.6%) with a mean age of 57.1±9.3 years. Two of them never took any COVID-19 vaccine at baseline, 5 of them only took the 1st dose and 40 of them took the 2nd dose. After 3 months intervention, 45 (90.0%) participants still remained in the study, and 33 of them received a new vaccine dose. The overall vaccination rate for the new dose increased from 0% at baseline to 73.33% (33/45, 95 CI%: 58.06% - 85.40%) at the end of the study; the vaccination rate of the 3rd dose achieved 76.92% (30/39, 95% CI: 60.67% - 88.87%). Compared with age-sex matched Hong Kong population, the rate of COVID-19 vaccine doses administered was higher in our study (9.33 v.s. 1.36 per 1000 person-days).
Conclusions: A 3-month mHealth education programme could significantly improve COVID-19 vaccine uptake in Hong Kong community residents in a relative short time period.
