E-Note # 29: Polio Eradication Initiative in Africa Yeilds Results, but Polio and Routine Immunization Programs Face Significant Challenges

African countries made substantial progress during 1998 in implementing the World Health Organization's (WHO's) Polio Eradication Initiative that aims to eradicate polio and achieve 90 percent vaccination coverage with 3 doses of Oral Polio Vaccine (OPV) by 2000. In 1998, 33 out of 36 countries conducted two rounds of National Immunization Days (NIDs) and most reported vaccinating over 80 percent of children under five years of age. The Bureau for Africa of USAID and its Missions provided support for surveillance and operational costs to 17 of the 36 countries.

The strategy for global eradication of polio, developed in 1988 by WHO and other partner agencies, is four-pronged:

  • High levels of routine immunization of children under one year of age with OPV to reduce the incidence of polio and prevent reintroduction of the virus in areas where it has been eradicated;
  • National Immunization Days (NIDs) to provide supplemental doses of OPV to all children under age 5, in order to vaccinate children who have no immunity or only partial immunity and to boost the immunity of others;
  • Acute Flaccid Paralysis (AFP) surveillance systems in all countries (including where polio has been eradicated) to identify every case of AFP and exclude the possibility of polio through laboratory testing;
  • "Mopping up" with door-to-door vaccination in areas where polio may still be circulating to interrupt further transmission of the virus.

POLIO AND EPI PROGRESS IN AFRICA

The countries of WHO's Africa Region made significant progress toward both polio eradication and expanded program on immunization (EPI) over the past year, according to reports presented at the 6th meeting of the Task Force on Immunization in Africa (TFI), held in December 1998, in Harare, Zimbabwe. Among the achievements applauded at the meeting were:

  • Development of a three-year action plan for polio eradication;
  • Acceleration of AFP surveillance, including laboratory investigations in 33 of the 47 WHO/AFRO countries (compared to 19 in 1996);
  • Highly successful NIDs in nearly all countries in the region;
  • An in-depth, independent review of the Regional EPI, which identified opportunities for improving both vaccination coverage and the quality of vaccination services;
  • Expansion of the technical and financial resources available for EPI - for example, funding has increased more than ten-fold over the past several years, from US$7 million in 1995 to US$73 million in 1998 and US$199 million (projected) for 1999;
  • Preparation of guidelines for the work of the African Region Inter-Agency Coordination Committee (ARICC), which comprises the donor agencies, non-profits, and other partners that provide funding for the TFI (including USAID and the USAID-funded BASICS Project).

MEETING THE CHALLENGES AHEAD

The TFI adopted over 30 specific recommendations to address the significant challenges ahead. Highlights of these recommendations include:

  • Development of a comprehensive policy and strategic plan for immunization and disease-control programs in the region: This will provide WHO/AFRO an opportunity to revisit current strategies in light of recent health sector reforms, stagnation and decline of vaccination coverage rates in the region, and the need for new management structures and administrative procedures in the wake of the program's rapid expansion.
  • Collaboration among all EPI partners to prevent civil unrest and war from disrupting EPI supplies and services: War in the Democratic Republic of Congo, Liberia, and Sierra Leone is increasing the risk of disease within transient populations, reducing the effectiveness of NIDs, and delaying AFP surveillance. EPI partners must work together to address these obstacles.
  • Improved strategic planning to better integrate programs, to enhance quality, and target priority needs: Even with recent increases in government financing for EPI, there is insufficient funding to implement key activities. For example, ARICC estimates that the shortfall in 1999 for carrying out the three-year plan of action for polio eradication will be almost 40 percent ($40 million out of the $103.5 million required).
  • Development of clear national policies on injection safety and better planning, management, and budgetary systems to improve injection technology: The high prevalence of hepatitis B and HIV/AIDS in Africa makes the safety of injections a high priority.
  • Establishment of centralized logistics teams and inclusion in national plans and budgets of all costs associated with cold chain and logistics rehabilitation: The current state of equipment and logistics impairs overall vaccine quality, and this problem will worsen in the near term. For example, more than half the existing cold chain equipment in the region is old, obsolete, or environmentally unsound and will need to be replaced during the next five years.

CONCLUSIONS

Polio Eradication can be achieved in Africa by the end of year 2000, but requires:

  • Implementation of extra-rounds of supplemental vaccination particularly in West and Central Africa , Angola and the Democratic Republic of the Congo;
  • Commitment of nationals and all partners at the regional and country level; > Availability of sufficient financial and human resources on a timely basis.

Routine immunization programs can benefit from the Polio Eradication Initiative only if the planning done for NIDs and the development of surveillance for polio includes a focus on strengthening the planning and improved surveillance for routine immunization services.

To this end, in FY 99, USAID/AFR intends to provide a small grant to WHO/AFRO and UNICEF to enable them to work jointly together with MOH/Immunization staff in four countries to try to address the challenges which may cause stagnating routine immunization coverage. In addition, it is expected that improved tools and strategies will be developed to plan and implement various disease control strategies supported by other immunization partners, complimenting and strengthening routine delivery of immunization services.
