  6. AFRO Measles TAG position on MCV2* TAG suggested criteria for MCV2 introduction: Achievement of MCV1 coverage >80%, maintained for at least three consecutive years using WHO/UNICEF best estimates of vaccine coverage; and Attainment of one of the two primary measles surveillance performance indicators for at least two consecutive years. *Report of the Second Meeting of the African Regional Measles Technical Advisory Group (TAG) Recommendations (2008) 6 AFRO Measles TAG Nairobi 2-3 June 2015

  7. WHO recommendation on MCV2 * All children should receive two doses of measles vaccine Minimum interval of one month between doses MCV1 at 9 or 12 months When MCV1 > 80% for 3 years then add MCV2 at: 15-18 months (if country has ongoing measles transmission) school entry (option if near elimination) Very high coverage (>90%) needed with both doses Mortality reduction: >90% national, >80% in every district Elimination: >95% in every district School entry screening for vaccination status *WHO Measles Vaccine Position Paper, WER Aug 2009 (http://www.who.int/wer/2009/wer8435.pdf) 7 AFRO Measles TAG Nairobi 2-3 June 2015

  18. MCV2 Post Introduction Evaluations Purpose to evaluate the impact of introduction on country s immunization program To rapidly identify problems needing correction PIE to be conducted 6 12 months following the introduction (WHO Recommendation) Assessment conducted at all levels of the health system by a team of experts (national and internationals) using adapted tools 18 AFRO Measles TAG Nairobi 2-3 June 2015

MCV2 PIEs implementation status Year Done 2013 Ghana (MCV2, PCV, RV) (August, 19 months after introduction) 2014 Burundi (MCV2, RV) (June, 17 months after introduction) Zambia (MCV, PCV, RV combined with EPI and in-depth surveillance review) (July, 12 months after introduction) 2015 Eritrea (MCV2, RV) (Feb, 31 months after introduction) Kenya (MCV2, RV) (May, 22 months after introduction) Planned Senegal Gambia Tanzania 20 AFRO Measles TAG Nairobi 2-3 June 2015

  21. MCV2 PIEs Key findings Programmatic areas Key findings Strategies to reach children > 9 months not planned Strategies for vaccination in second year of life not established Opportunities to link MCV2 with other child health activities >1 year not fully explored Strategies for defaulters tracing not in place Lack of clarity when zero-dose children come in for MCV2. Knowledge of HCW sub-optimal (training for MCV2 not given sufficient attention since it is an old vaccine ) Service delivery, integration, reducing missed opportunities 21 AFRO Measles TAG Nairobi 2-3 June 2015

  22. MCV2 PIEs Key findings Programmatic areas Key findings Provision of immunization service > 1 year new to care takers Sub-optimal knowledge of EPI clients on MCV2 and immunization activities > 1 year Demand creation activities limited Opportunities to increase demand creation exist but are not fully harnessed (health education during EPI sessions/antenatal visits, health visits, mass media, etc..) Demand creation 22 AFRO Measles TAG Nairobi 2-3 June 2015

  23. MCV2 PIEs Key findings Programmatic areas Key findings Unstable population figures Target population for MCV2 new to the program and not widely understood Recording of MCV doses still a challenge Monitoring of MCV2 not fully established Poor recording of MCV2 doses Monitoring of MCV2 at all levels not established High MCV1-MCV2 dropout rates observed (reflecting low MCV2 coverage) but not monitored Impact of MCV2 introduction on vaccine utilization/wastage is not systematically monitored Monitoring of doses/coverage /dropout 23 AFRO Measles TAG Nairobi 2-3 June 2015

  24. Improving MCV2 coverage Way forward 24 AFRO Measles TAG Nairobi 2-3 June 2015

  25. Modeling MCV2 impact Theoretical model 1,400 Thousands 1,300 No MCV2 MCV1 = 80% Assumed constant over years 1,200 1,100 1,000 900 MCV2 = 40% 800 MCV2 = 50% 700 600 MCV2 = 60% Birth cohort 500 MCV2 = 70% 400 MCV2 = 80% 300 MCV SIAs MCV2 = 90% 200 100 0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Susceptible accumulated above birth cohort Recommended time for measles SIA Changes in susceptible population by level of MCV2 coverage in a theoretical population with a birth cohort of 500,000, assuming MCV1 coverage 80% at 9 months maintained over time. At coverage 70%, 80% and 90% it will take 9, 13 and 22 years respectively for the population of susceptible to accumulate above the birth cohort 25 AFRO Measles TAG Nairobi 2-3 June 2015

  26. Way forward to improve MCV2 performance 1. Institution of a pre-MCV2 introduction readiness assessment/planning tool developed by WHO/UNICEF? 2. WHO-AFRO to institute reporting on dropout between MCV1 and MCV2 as key performance indicator (to be reported in feedback bulletin and included in monitoring charts ) for countries with MCV2 3. WHO and UNICEF to conduct additional operational research on strategies/best practices to improve MCV2 coverage around: service delivery, demand creation and integration with 2nd year of life activities 26 AFRO Measles TAG Nairobi 2-3 June 2015

  27. Way forward to improve MCV2 performance 4. Sharing lessons learned and best practice from other countries to inform MCV2 introduction and performance 5. Changing EPI target age from the historic 9 months (0- 11 months) to under 2 or under 5 years 6. Monitoring the implementation of PIEs recommendations 27 AFRO Measles TAG Nairobi 2-3 June 2015

  28. Conclusion and questions to the TAG 28 AFRO Measles TAG Nairobi 2-3 June 2015

  29. Conclusion 19 countries in WHO/AFRO Region (40%) have introduced MCV2 into their RI schedule, with more countries planning to introduce MCV2 in the near future Concerns remain over low performance of MCV2 and appropriate actions should be taken to improve MCV2 performance Not all countries have exploited MCV2 introduction to make policy and practice changes to increase MCV1 and MCV2 coverage 29 AFRO Measles TAG Nairobi 2-3 June 2015

  30. Questions to the TAG on MCV2 1. Is it time the TAG revisit its MCV2 introduction criteria that were set in 2008 (coverage criteria, surveillance criteria)? 2. Should WHO institutes a pre-introduction assessment (6, 8 months prior to MCV2 introduction?) 3. Should AFRO countries institute universal school entry MCV checks and referral when there is not evidence of 2 doses of MCV? 30 AFRO Measles TAG Nairobi 2-3 June 2015
