Definition: Proportion of polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks* with timely detection and response**
  • Numerator: Number of known polio, measles, meningococcus, yellow fever, cholera, and Ebola outbreaks with an outbreak response vaccination campaign with timely detection and response*
  • Denominator: Number of known polio, measles, meningococcus, yellow fever, cholera, and Ebola outbreaks with an outbreak response vaccination campaign

**Definitions for timely detection and response vary by disease and are consistent with WHO VPD surveillance standards, International Coordinating Group (ICG) on Vaccine Provision performance standards, and disease eradication, elimination, or control strategies’ outbreak response standards.



  • Ebola: 51 days from 1st case onset of symptoms to start of response vaccination campaign
  • Yellow Fever: 86 days from 1st case onset of symptoms to start of response vaccination campaign.
  • Wild Poliovirus: 63 days from 1st case onset of paralysis to start of response vaccination campaign.
  • Circulating Vaccine Derived Poliovirus: 63 days from 1st case onset of paralysis to start of response vaccination campaign.
  • Measles (non-endemic): 69 days from 1st case onset of symptoms to start of response vaccination campaign.
  • Measles (endemic): 35 days from when incidence crosses epidemic threshold to start of response vaccination campaign.
  • Meningococcus: 27 days from when incidence crosses epidemic threshold to start of response vaccination campaign.
  • Cholera: 27 days from when incidence crosses epidemic threshold to start of response vaccination campaign.
Method of estimation:

Step 1) Across all WHO Member States, calculate the total number of outbreaks for each pathogen which required a vaccination response.

Step 2) Of those, calculate the number of outbreaks with timely detection and response.

Data source: ICG, MRI, GPEI, WHO, national immunization and disease surveillance programs. Information will be systematically collected from national immunization and disease surveillance programs to provide data for regional and global level data.

The IA2030 Scorecard visualizes the monitoring and evaluation indicators of the IA2030 Framework for Action endorsed in 2020 by the World Health Assembly, with the support of countries and partners. The scorecard is a collaborative effort led by MOMENTUM Country and Global Leadership working in partnership with the IA2030 Working Groups on Monitoring & Evaluation and Communications & Advocacy, with oversight from the IA2030 Secretariat and IA2030 Coordination Group (IACG).
