Major achievements -1

• Hepatitis recognized among health priorities• Hep B vaccine routinely used in most countries of

the Region (43/52) • All CCEE and NIS have HepB in immunization

schedules (26/29 target newborn and infants)• All high endemic countries provide birth dose• Immunization is free of charge • Staff well trained, capable and motivated

Page 23: EPIDEMIOLOGY OF HEPATITS B AND …...PROGRAMMES IN THE EUROPEAN REGION WHO Strengthening immunization systems and introduction of hepatitis B vaccine in Central and Eastern Europe

WHO Regional Office for Europe

Major achievements -2

• Increased political commitment and support • High demand from public for HepB immunization• Better partnership and collaboration between

MoHs and partners• Strengthened surveillance systems

– notification of acute hepatitis B is mandatory – some countries do have very complete data

• Increased understanding of the need for monitoring progress

Page 24: EPIDEMIOLOGY OF HEPATITS B AND …...PROGRAMMES IN THE EUROPEAN REGION WHO Strengthening immunization systems and introduction of hepatitis B vaccine in Central and Eastern Europe

WHO Regional Office for Europe

Major challenges• Economic and political instability in some countries• Inadequate allocation of resources from State funds• Unequal economic development of regions and districts within

countries• Accuracy of data collected (esp.birth dose)• Surveillance systems

– not well established or weak in some countries– methods used vary

• Limited monitoring and impact assessment• Lack of integration and interaction between highly-developed

private sector and PHC

• SUSTAINABILITY!!!!

Priorities and future actions

• Advocacy to ensure political commitment and continued funding

• Technical support to sustain progress and improve implementation

• Building management capacity for monitoring performance at district level, with timely and adequate response

• Strengthening surveillance systems, improving quality of data

• Assessment of the programme and monitoring impact • Communication and advocacy with all stakeholders

through provision of evidence and information
