Political Support
  • Personal involvement of his Excellency President Karzai in launching of SIAs
  • Constitution of Polio Action Groups (Health, Education, Information, Religious Affairs, Defense, ISAF/NATO/CF) at the national and provincial level.
  • Involving the Governor of Kandahar Province
    • Governor participation in the Geneva Consultation
    • Appointment of ‘Polio Officer’ in the office of governor – who is charged with authority to coordinate SIAs between health & other departments, and with district governors
innovative measures taken
Innovative Measures Taken
  • Use of mOPV1& mOPV3 in South, SE & Eastern regions as appropriate
  • Focused District Strategy (FDS)
    • One day operation, using village based vaccination teams leading to better Community involvement
  • Phased Approach in Hilmand & Kandahar
  • In conflict areas, using windows of opportunity to vaccinate children even after the regular campaign days
  • Using UN Peace Day as “Window of opportunity” to increase access in security compromised area
  • Vaccination of border population on both sides at the same time.
  • Conducted special social mobilization activities in the infected districts
  • Special focus during the trainings on how to reach young children
  • Combining the OPV with the Measles & MNT vaccination campaigns
summary
Summary
  • Most of Afghanistan is polio free but large immunity gaps in young children allow continued polio virus transmission in the southern region.
  • Main cause of the problem is the conflict situation which impedes the access to children.
  • Immunity among the children in other regions looks satisfactory, not allowing the establishment of transmission.
  • Quality of campaign has deteriorated in the South mainly due to security reason and is not good enough to stop circulation.
  • Immunity gaps still persists & recent type 3 circulation poses risk of spread to adjacent areas
  • Interrupting virus transmission requires reaching all children through high quality vaccination rounds and to focus special attention on children in border areas and mobile populations.
key challenges
Key Challenges
  • Deteriorating Security & Access Issue:
    • Active conflict / on going operations during the campaign days leading to an environment of fear for vaccination staff
    • Although reported coverage is 100% in most of districts, the coverage is less than 50-60% in the southern region ( >95% coverage required to interrupt polio virus transmission)
    • Difficult to supervise & monitor the campaign in security compromised areas
    • Weak management, misappropriation of funds and improper staff selection issues, sometime using security as smoke screen
  • Vaccinating moving populations (Seasonal, Nomads and Cross border )
  • More involvement & participation of community elders needed, particularly in unsecured area
  • Role & responsibility BPHS NGOs in NIDs need more clarity
  • Program Funding Gap of 30 million USD for 07-08
the way forward
The Way Forward

Days of Tranquility (DOT)

No military operations during campaign days – so vaccinators can access all children and vaccinate safely. All parties in conflict need to agree on DOT

Commitment at higher level need to be transmitted at the provincial and district levels

Maintaining high population immunity in other parts of the country

Sustaining communications activities & its expansion to cross border activities

Improving routine immunization and optimizing experience of PEI

Fund raising to bridge the funding gap
