disease situation
Disease Situation
  • First identified in 2003
  • 31/33 provinces have confirmed cases (286/444 districts)
  • Incidence varies across the country
    • Endemic in Java, Bali, Sumatra and South Sulawesi
    • Lower incidence in eastern provinces
    • Based on limited surveillance
  • Both commercial and village poultry
  • Chickens, quails and ducks affected
  • Human cases since July 2005
9 strategies for control 2004
9 Strategies for Control - 2004
  • Improvement of bio-security
  • Vaccination in infected and suspected areas
  • Depopulation (selective culling) and compensation
  • Control movement of live poultry, poultry products and farm waste
  • Surveillance and tracing back
  • Restocking
  • Stamping out in newly infected areas
  • Public awareness
  • Monitoring and evaluation

* Decree of DG of Livestock Services, Feb 2004

national strategic plan
National Strategic Plan
  • National Strategic Work Plan for the Progressive Control of HPAI in Animals 2006-2008
  • 9 elements :
    • Campaign Management Unit
    • Enhancement of HPAI Control
      • Including vaccination
    • Surveillance and epidemiology
    • Diagnostic laboratory services
    • Animal quarantine services
    • Regulation
    • Communication
    • R & D
    • Poultry Industry Restructuring
  • Reviewed in June 2007 – no substantive change, but recognised need to intensify campaign
  • Improve the management, planning and capacity for HPAI control
  • Reduce risk / Improve HPAI prevention
  • Improve detection and response
reducing risk
Reducing Risk
  • There are many high risk practices along the production and market chain
  • These must be identified and the risk eliminated or reduced
  • But this will take time, so…
  • Vaccination of high risk populations will be necessary until risks reduced
risk pathways

risk reduction
Risk Reduction


  • Vaccine
  • Farm biosecurity
  • Ducks
  • Transport/dealers
  • Traditional markets
  • Hatcheries
  • Information, education and communication
  • In mid 2003, AI was detected in Central Java and has spread to West Java and East Java…. and 2004 spread to Lampung, North Sumatera, Bali and South Sulawesi.
  • Poultry industry was infected and movement of commercial poultry might be the cause of spread to other islands.
  • Limited compensation fund was available for Sector 4 and Sector 3 (small scale)
  • Sector 1 and 2 no compensation
  • Mid 2004, vaccination policy was implemented by Government.
vaccination strategy
Vaccination Strategy
  • Mass vaccination in mid 2004:
    • 300 M doses available
    • Inactivated H5N1 local isolate
    • Free of charge
    • Backyard and small farmers of any species
  • Mass vaccination continued in 2005 and early 2006
  • Vaccination in sectors 1, 2 and 3 (breeders and layers)
    • at their own cost
    • with coverage estimated to be 90% in commercial layer and 100% in breeding flocks
  • Mid 2006 due to limited vaccines – targeted vaccination:
    • Inactivated LPAI vaccine (H5N2)
  • 2007 – continued targeted vaccination of some populations in high risk provinces
ai vaccines
AI Vaccines

Vaccine use (GoI):

  • 2004 : 132m doses
  • 2005 : 143.4m doses
  • 2006 : 102.9m doses
  • 2007 : 98.5m doses

Registered seed strains:

  • H5N1: A/Chicken/Legok/2003
  • H5N2: A/Turkey/England/N28/73


  • H5N9: A/Turkey/Wisconsin/68
vaccination problems
Vaccination problems
  • Complex programme management in the autonomy era
  • Limited resources against scale of task
    • Staff, equipment, operating, vaccine
  • Low vaccination coverage in Sector 4 (wide area, large population, free range)
  • A range of species infected - native chicken, commercial chicken, duck, quail
  • Poor biosecurity/Sector 4
  • Vaccination in poultry industry – re-occurrence of outbreaks by end 2005
  • And vaccine efficacy issues (results of SEPRL-DGLS-AAHL-FAO)
  • Review of antigenic variability of AI viruses in Indonesia
  • Virus isolates required for further assessment…

summary of challenge studies
Summary of Challenge Studies
  • PWT-WIJ/06 resistant to most vaccines
  • SMI-HAMD/06 was susceptible to most vaccines
  • Papua/06 was intermediate

Source: Swayne, 2007

  • What is the significance of PWT-WIJ/06 ?
  • Need representative viruses
    • Spatial, enterprise, species
    • Epidemiological information: vaccination status, clinical signs etc
    • Collected overtime
summary of sequence analysis
Summary of Sequence Analysis
  • Isolates from Indonesia fall within one clade
  • There are 3 other isolates that group with the PWT-WIJ/06
  • These 4 isolates appear to be somewhat different from the majority of isolates so far submitted

  • Increased collection of representative isolates and mapping
  • Challenge tests/strain selection
  • Recommend Vaccination strategy
    • Identify efficacious current vaccines
    • Identify new seed strains, if required
    • Ongoing monitoring
work already carried out on going
Work already carried out/on-going
  • Virus characterization by DNA sequencing (AAHL, Bbalitvet, VLA)
  • Efficacy testing of vaccine (SEPRL)
  • HI tests (SEPRL, VLA, Bbalitvet)
  • Antigenic cartography (Erasmus)
  • Under progress- vaccine construction (rev genetics) and autogenous vaccine (SEPRL)
  • Isolate sharing need to be increased
  • HPAI remains endemic in many areas
  • Long term approach to risk reduction is required
  • Improved surveillance with better understanding of disease epidemiology
  • Commercial industry support is critical
  • Vaccination can be an important tool to reduce circulating H5N1 virus
    • Needs adequate resources and management
    • Monitoring of vaccination program critical
    • Is only component of successful disease control
