Abstract
Introduction: Infectious diseases are one of the burdens in terms of their effects and implications on humans. One of the ways to overcome this infectious disease is through the provision of vaccines that can prevent or at least minimize the effects of the disease. This study aimed to estimate the prevalence of self-reported hepatitis B vaccination status by socio-demographic characteristics among adults in Malaysia.
Method: National Health and Morbidity Survey (NHMS) 2020 is a cross-sectional survey with complex survey design. NHMS 2020 data for hepatitis B module was collected through questionnaire ""have you ever get vaccinated with Hepatitis B shot"" between August to October, 2020 by face-to-face interview. Descriptive, chi-square and complex sampling analysis were done using SPSS v.26 software. Results: A total of 4,136 respondents participated in this study. The prevalence of respondents who completed three shots for hepatitis B was 17.7% (95% CI: 13.2-23.2), either got one or two shots of hepatitis B was 7.2% (95% CI: 5.0-10.2), never got shot for hepatitis B was 53.2% (95% CI: 45.6-60.7) and not sure was 21.9% (95% CI: 16.5-28.4). According to strata, gender and age group, majority who those never got shot for hepatitis B were those living in the urban area (74.3%, 95% CI: 67.2-80.3), males (51.8%, 95% CI: 48.2-55.3) and aged 31 years and above (62.8%, 95% CI: 57.3-68.1). For respondents either got one or two shots of hepatitis B, prevalence was highest among those living in the urban area (88.7%, 95% CI: 79.6-94.1), males (66.0%, 95% CI: 55.8-74.9) and aged 31 years and above (62.1%, 95% CI: 51.4-71.8). Majority who completed three shots of hepatitis B were among those living in the urban area (84.2%, 95% CI: 73.7-91.0), females (54.7%, 95% CI: 49.6-59.6) and aged 31 years and above (56.6%, 95% CI: 50.3-62.7). From 21.9% respondents were not sure about their vaccination status, majority were living in the urban area (76.4%, 95% CI: 65.5-84.6), males (50.7%, 95% CI: 47.1-54.3) and aged 31 years and above (61.9%, 95% CI: 57.1-66.5). There were significant associations between self-reported hepatitis B vaccination status with strata (p<0.001), gender (p=0.005) and age group (p<0.001). Discussion: The high prevalence was shown among those who never receive hepatitis B vaccination and highest among the age group 31 years and above. This may happen because the hepatitis B vaccination program for children was implemented in 1989. However, prevalence of three shots of hepatitis B also highest among this group showed they had an initiative to take the vaccine personally, maybe because of future study abroad, occupation purpose or self-awareness. This study provides an overview of the immunity to hepatitis B profile and helps in the improvement of hepatitis B vaccination programs among adults in Malaysia as recommends by The Advisory Committee on Immunization Practices (ACIP).
