[Hepatitis B vaccination strategies]

With the introduction of a vaccine against hepatitis B in the early 1980s, a vaccination strategy targeted at high risk groups was implemented in most developed countries. Although such a strategy is efficient on an individual basis, it has been shown that it only has a limited impact on the overall rate of infections in the population. Public health authorities were therefore prompted to additionally recommend a universal vaccination strategy to reduce and ultimately eliminate hepatitis B infections. The option to primarily vaccinate infants, adolescents or both age groups depends on the epidemiological situation of a country, the availability of organisational facilities, financial resources and acceptability. Combining a targeted and a universal vaccination strategy provides the optimal protection against hepatitis B, both at an individual and population level.
