Prevalence and factors associated with hepatitis B surface antibody seroprotection among healthcare workers undergoing laboratory testing at Eastgate Clinic, Windhoek, Namibia: A retrospective cross-sectional study

Healthcare workers are occupationally exposed to blood and body fluids and require effective protection against hepatitis B virus infection.
