Abstract

The vaccination of close contacts could offer indirect protection to people with diabetes; this is known as “herd immunity.” The aim of this study is to investigate the vaccination rates of people with diabetes and their household contacts in Hong Kong. Research design and methods Face-to-face interviews with 158 patients diagnosed with Type 2 diabetes and aged ⩾65 years were conducted in clinics. Telephone interviews were then conducted with 281 adult household contacts. Results Seasonal influenza vaccination rates were 54.5% and 27.4%, in people with diabetes and their contacts, respectively. The vaccination status of patients was not significantly associated with the vaccination of their household contacts (p = 0.073). Among household contacts, children or the elderly, the partners or couples of patients, and those with more hours of daily contact, or with chronic conditions, were associated with higher vaccination rates. However, only age remained significant after adjusting for confounding factors in logistic regression models. Conclusions The low vaccination rates of people with diabetes and their close contacts highlight the need to promote vaccination in susceptible populations and to educate the public about herd immunity.
