Priorities in the Measles and Rubella Research Agenda William Moss, MD, MPH Johns Hopkins Bloomberg School of Public Health 11th Annual Meeting of The Measles and Rubella Initiative September 18, 2012
Global Measles and Rubella Strategic Plan • High population immunity and vaccine coverage • Effective surveillance, monitoring evaluation • Outbreak preparedness and response • Public confidence and demand for immunization • Research and development
Developing a Research Agenda Clear and explicit program goals Specified target audience Answerable research questions Strategies to address research questions Milestones and review of progress Flexibility in adapting research agenda
Measles Landscape Analysis for the Bill and Melinda Gates FoundationDecember 2008 • Effect of measles activities on health systems • Improve monitoring by: • developing field-friendly laboratory assays to validate coverage • developing immunization (and child-health) registries • Improve surveillance by obtaining: • data on measles age-specific sero-prevalence • baseline data on rubella • Commission a MCV market supply study
Public health questions to which modelling can have a major contribution Improve existing modelling methods to estimate mortality Assess the burden of CRS Optimize strategies for measles and rubella control birth rate population density rural-urban migration seasonality of infection contact patterns Potential impact of waning immunity Cost-effectiveness of different goals and strategies Measles Landscape Analysis

Measles Epidemiology Epidemiologic characteristics of measles in India Causes of outbreaks in high coverage settings Age infants lose protection from maternal antibodies Implications of administering MCV1 prior to 9 months Susceptibility and transmission among adults Susceptibility among HIV-infected adults
Vaccine Development and Effectiveness, and Alternative Vaccine Delivery Methods Vaccine effectiveness in densely-populated settings Improved vaccines: thermo-stable vial temperature monitors self-reconstituting vials alternative delivery methods
Surveillance and Laboratory Methods Global distribution of measles virus genotypes Rapid diagnostic tests for measles and rubella High-throughput assays for neutralizing antibodies Higher resolution for virologic surveillance Differentiate wild-type and vaccine immunity
Immunization Strategies Increase uptake of routine 1st and 2nd doses Maximize SIA coverage Monitoring vaccination coverage (RI and SIA) Vaccinating difficult to reach populations Misconceptions and attitudinal barriers Increase demand for vaccination Outbreak response immunization activities
Mathematical Modeling and Economic Analyses Modeling progress toward measles eradication Threshold population size and susceptible density required to sustain measles virus transmission Economic burden of measles outbreaks and response in low and middle income countries
Rubella Control and Elimination Birth rates and the epidemiology of rubella and CRS Methods and costs for identifying CRS cases Refusal and acceptance of MMR vaccine Global distribution of rubella virus genotypes Economic burden of rubella and CRS
Research Questions from Measles Management Meeting Americas Identification of high risk groups Transmission in settings of high vaccine coverage Europe Role of adolescents and adults Waning immunity Economic analyses and disease burden modeling Burden of rubella and CRS Communication strategies Western Pacific Transmission among infants, adolescents and adults Outbreak response: triggers, threshold and scope
SAGE Working Group on Measles and Rubella
Terms of Reference Identify gaps in essential evidence and programme barriers to achieving measles and rubella/CRS elimination targets and present SAGE with proposed areas for operational or basic science research.
Approach • Define the context for research priority setting • Identify research questions and knowledge gaps • Define criteria for research priority setting • Score listed research questions using criteria • Address stakeholder values • Refine questions and implementation process • Periodic re-evaluation of research priorities
Summary Many key research questions have been identified Next steps Consensus on highest priority research questions to advance strategic plan Develop strategies to address these questions Identify milestones and targets Assess progress Adapt research agenda to changing need
