At least five different types of viral hepatitis cause problems of significant public health importance in Africa, where together they constitute a huge burden of disease. But until now, efforts to control the infections have been largely piecemeal. Analysis of the strategies needed to control each virus, however, reveals major overlaps.We propose that the control of these infections in the WHO African...
To determine the age specific immunity profile for rubella from three discrete study populations in Papua New Guinea, and to inform policy regarding the possible introduction of rubella vaccine.In 2005, the Western Pacific Region (WPR), of which Papua New Guinea (PNG) is a member state, declared the goal of regional measles elimination by 2012. Recently, WPR has incorporated an accelerated control...
The Expanded Programme on Immunization (EPI), launched in 1974, has developed and implemented a range of strategies and practices over the last three decades to ensure that children and adults receive the vaccines they need to help protect them against vaccine-preventable diseases. Many of these strategies have been implemented, resulting in immunization coverage exceeding 80% among children one year...
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,...
To measure immunization coverage among children aged 12–23 months in Papua New Guinea (PNG) and to assess if and why there are differences between hard-to-reach and more accessible communities.WHO cluster sampling methodology was employed to measure immunization coverage in PNG's four regions. Survey data were re-analyzed according to a local assessment of geographical accessibility indicated by census...
We aimed to determine the proportion of the population in Madang (Papua New Guinea) immune to measles infection by age groups, with respect to immunization status and study location, using dried blood sampling technology. We performed a prospective cross-sectional sero-survey. Population immunity against measles was sub-optimal (77%) and reported measles vaccine coverage in children <10 years of...
Integration of health services brings together common functions within and between organizations to solve common problems, developing a commitment to a shared vision and goals, and using common technologies and resources to achieve these goals. Integration has been the frustrated rally call of Primary Health Care for 30 years. This paper discusses the process of integrating child survival strategies...
Reaching mothers and their newborn infants around the time of birth with adequate health services has long been a difficult problem in developing countries. In parallel, similar problems have arisen in attempting to deliver hepatitis B (HepB) vaccine to infants born at home in many countries where mother-to-infant transmission is common. It is logical, and supported by experience in Indonesia, to...
Fourteen data loggers were packed with vaccine vials at the national vaccine store, Port Moresby, Papua New Guinea (PNG), and sent to peripheral locations in the health system. The temperatures that the data loggers recorded during their passage along the cold chain indicated that heat damage was unlikely, but that all vials were exposed to freezing temperatures at some time. The commonest place where...
Hepatitis B virus infection is a serious problem globally, and particularly in the Western Pacific Region where the population suffers disproportionately from the infection and its sequelae. By 2001, every immunization programme in the Region had included hepatitis B vaccine in their schedule. However, many challenges remain if every one of the 26 million children born in the 37 countries and areas...
While a number of studies remain to be completed, evidence is mounting that there is no demonstrable risk for infants immunized with vaccines containing thiomersal. Epidemiological studies in the US have shown no developmental or other central nervous system abnormalities resulting from exposure to vaccines containing thiomersal. During the initial evaluation of thiomersal in vaccines during 1999,...
There is an ever-expanding technology that is aimed at making the administration of vaccines safer. Conventional ways of administering vaccines are being upgraded, modified or replaced by a wide variety of innovations. The paradigm of liquid vaccines, needles and syringes is slow to change, but already developments are ocurring that will change for ever the way vaccines are administered and will improve...
