Abstract:
The hepatitis B virus is a public health threat, chronically infecting over 240 million persons worldwide. The hepatitis B vaccine is 90% effective in preventing perinatal transmission if the first dose is given within the first 24 h of life, followed by a minimum of two subsequent doses. Antigua and Barbuda instituted a hospital-based birth dose vaccination policy in October 2021. Data were extracted from hospital logbooks from November 2021 to October 2022, and a database was created. Frequency distributions of the hepatitis B birth dose, barriers to administration, and maternal and healthcare system factors were analyzed. The positive maternal HBsAg prevalence rate was 0.6%. The timely and total birth dose coverage was 72% and 81%, respectively. In total, 10.5% of parents refused the vaccine, of which 76% either felt uncomfortable or preferred to wait. Moreover, 100% of hepatitis B-exposed babies were vaccinated, with 83% of them receiving the Hepatitis B Immunoglobulin. Barriers to vaccine administration included vaccination hesitancy, gaps in knowledge of medical staff, and the inconsistent vaccination supply. Instituting a quality improvement team, health information system, robust educational efforts, and addressing barriers will make achieving the WHO programmatic targets of eliminating mother-to-child transmission of hepatitis B by 2030 possible.
