Background MYP for Universal Immunization Program (UIP) in India – Goal : 67% reduction of measles related mortality by 2010 – Goal : 90% reduction in measles related mortality by 2013 Widely disparate MCV1 performance through RI in 35 states and UTs – 99% in Goa vs. 47% in Uttar Pradesh* Variable improvement in MCV1 coverage through RI – Bihar: MCV1, 46% (2006) to 54% (2008) – Uttar Pradesh has remained static at 47% Proposed and under consideration Source: DLHS 3 ( ) 1/16/201417IAPCOI Measles/MMR - Dec 2011

NTAGI recommendations, 2009: MCV2 delivery strategies MCV2 delivery strategies for states with low MCV1 coverage (< 80%) – SIA targeting children 9 month to 10 years : Rajasthan and Madhya Pradesh : Bihar, Chhattisgarh, Jharkhand, UP and Assam MCV2 delivery strategies for states with high MCV1 coverage (>= 80%) – 18 states and union territories identified – MCV2 offered through UIP at months of age Source: National Technical Advisory Group on Immunization (NTAGI); 3 August /16/201419IAPCOI Measles/MMR - Dec 2011

MCV2 introduction: State-specific delivery strategies SIA in 14 states: – Target population (9 mo-10 years): 134 million – Vaccine doses and AD syringes: 147 million – Mixing syringe : 29.5 million MCV2 in routine immunization in 21 states: – Annual targets 1-2 year population: ~10 million Vaccine doses: ~12 million RI: MCV1 > 80%: 21 states SIA: MCV1 <80%: 14 states 1/16/201421IAPCOI Measles/MMR - Dec 2011
