Global polio eradication is nearing, but post-certification plans are crucial. Maintain surveillance and vaccine stockpiles to prevent future outbreaks from wild or vaccine-derived polioviruses.

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Vaccinology

Background:

  • Global wild poliovirus eradication is nearing completion.
  • Post-certification planning is essential to prevent future outbreaks.
  • Vaccine-derived polioviruses (VDPVs) and laboratory-related risks pose ongoing threats.

Purpose of the Study:

  • To address critical questions regarding post-polio eradication strategies.
  • To evaluate the optimal vaccine stockpile composition (e.g., monovalent oral poliovirus vaccine - mOPV).
  • To assess the role and efficacy of inactivated poliovirus vaccine (IPV) in diverse settings.

Main Methods:

  • Review of existing literature and expert consensus on polio eradication and post-certification.
  • Analysis of uncertainties surrounding vaccine policies, financing, and management.

  • Evaluation of risks associated with declining population immunity and potential VDPV spread.

    • Main Results:

    • Significant uncertainties remain regarding the composition, financing, and management of post-certification vaccine stockpiles.
    • The efficacy of inactivated poliovirus vaccine (IPV) in low-hygiene settings requires further investigation.
    • Declining immunity levels could increase the risk of VDPV emergence and spread.

    Conclusions:

    • Continued polio vaccination is necessary until a coordinated post-certification policy is established.
    • Further research is needed on vaccine strategies, particularly IPV's role.
    • A comprehensive global strategy is required to manage risks post-eradication.
