Implementing a birth dose of hepatitis B vaccine for home deliveries in Africa--too soon?

Despite the recommendation of the World Health Organization (WHO) to provide the first hepatitis B vaccine dose at birth (within 24h), there are epidemiological, economic and logistical reasons why this may not be the best approach for home births in Africa. The WHO policy presupposes that the epidemiology of hepatitis B infection in Africa is similar to the rest of the world and that the organizational, infrastructural and financial support is adequate. While babies born in health facilities may be relatively easy to immunize at birth, health systems and infrastructures in many resource-poor countries in Africa would be severely challenged, if required to reach home deliveries within 24h of birth.
