NTAGI recommendations 2009: Surveillance and CFR estimates
• Surveillance:
– Serve the data needs of the immunization programs
– IDSP-lead role with technical support from WHO-NPSP and other partners
• Geographic expansion in consultation with the states:
– Preceding the phased implementation of measles SIAs• 2009-2010: Rajasthan, Madhya Pradesh and Orissa
• 2010-2011: Bihar, Chhattisgarh, Jharkhand, Uttar Pradesh (UP) and Assam
• Estimates of case fatality ratio (CFR):
– Through outbreak surveillance system in one high burden state
– Technical support from partners

Response to second dose of Measles Vaccine
•Gomber et al after 2 year vaccination 20% had detectable antibody
•Multicentric study 100% antibody conversion on 2nd dose
•Single dose Mumbai – 93%, Pune – 82%, Indore – 50%
•Effect of 3rd dose ??? – 65% ? IAP

Measles Coverage (DLHS-3)
04/10/23 16IAPCOI Measles/MMR - Dec 2011
Background• MYP for Universal Immunization Program (UIP) in India
– Goal 2005-10: 67% reduction of measles related mortality by 2010
– Goal 2010-17: 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%

NTAGI recommendations, 2009:MCV2 delivery strategies
• MCV2 delivery strategies for states with low MCV1 coverage (< 80%)
– SIA targeting children 9 month to 10 years • 2009-10: Rajasthan and Madhya Pradesh
• 2010-11: 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 16-24 months of age

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

MCV2 introduction through catch-up vaccination campaign (MCUP) Phase 1
• In three phases– Target: 134 million in 351 districts
• Phase 1: – 45 districts from 13 states with ~13
million target children• 9 district from Chhattisgarh
• 5 districts from each of the 6 states (Bihar, Jharkhand, Rajasthan, Madhya Pradesh, Gujarat & Haryana)
• 1 district from each of the North-East states
• Phase 2 to take place from September 2011
• Phase 3 in 2012
