Abstract

Background

Despite vaccination and booster shots proving more effective than workplace measures in controlling the COVID-19 pandemic, hesitancy towards compulsory booster shots remains. This study aimed to evaluate the effectiveness of an enhanced educational intervention program in improving the acceptance of COVID-19 booster shots and reducing breakthrough infections among non-healthcare workers in Hong Kong.

Methods

In this 9-month randomized controlled trial (RCT), workers were randomly allocated to either the intervention or control group. The intervention group received educational sessions at baseline and at 3-month, covering general health and evidence-based information on the efficacy and safety of COVID-19 vaccines and booster shots. The control group received only general health information. All participants were followed up for an additional 6 months. The primary outcomes were intention and acceptance of booster shots, as well as breakthrough infections. The DASS-21 scale was used to evaluate participants’ mental health status, and two-way mixed ANOVA to analyze the group effect. A difference of ≥ 5 % in booster uptake between the intervention and control group indicated a practical significance in infection control.

Results

Among 310 consenting workers, 282 (91.0 %) of them completed the trial. At recruitment, the booster uptake rate was similar between the intervention and control groups (62.0 % vs. 62.1 %). After the educational intervention sessions, the intervention group showed a higher booster uptake rate (76.1 % vs. 67.9 %). A lower rate of breakthrough infection was observed in the intervention group during the latest follow-up period (23.2 % vs. 29.5 %); however, no change in the intention to get booster shots were recorded for all subjects.

Conclusion

This enhanced educational intervention program significantly improves booster uptake rates and reduces COVID-19 breakthrough infection rates among non-healthcare workers. (Trial registration: ClinicalTrials.gov - NCT05197673)

期刊介绍： The Journal of Infection and Public Health, first official journal of the Saudi Arabian Ministry of National Guard Health Affairs, King Saud Bin Abdulaziz University for Health Sciences and the Saudi Association for Public Health, aims to be the foremost scientific, peer-reviewed journal encompassing infection prevention and control, microbiology, infectious diseases, public health and the application of healthcare epidemiology to the evaluation of health outcomes. The point of view of the journal is that infection and public health are closely intertwined and that advances in one area will have positive consequences on the other. The journal will be useful to all health professionals who are partners in the management of patients with communicable diseases, keeping them up to date. The journal is proud to have an international and diverse editorial board that will assist and facilitate the publication of articles that reflect a global view on infection control and public health, as well as emphasizing our focus on supporting the needs of public health practitioners. It is our aim to improve healthcare by reducing risk of infection and related adverse outcomes by critical review, selection, and dissemination of new and relevant information in the field of infection control, public health and infectious diseases in all healthcare settings and the community.
