Measles & Rubella Laboratory Network

The Measles & Rubella Laboratory Network (MRLN) is an international laboratory coordination system supporting World Health Organization-led eradication and elimination initiatives for measles and rubella through standardized diagnostics, surveillance, and outbreak response. Established through collaboration among World Health Organization Regional Office for Africa, Pan American Health Organization, European Centre for Disease Prevention and Control, and national public health institutes such as Centers for Disease Control and Prevention, the network links reference, regional, and subnational laboratories to inform policy by generating virologic and serologic evidence. The MRLN interfaces with global health partners including United Nations Children's Fund, Gavi, the Vaccine Alliance, Bill & Melinda Gates Foundation, and technical agencies like Africa Centres for Disease Control and Prevention.

Overview

The network functions as a tiered system of reference laboratorys and field laboratories analogous to structures in Global Polio Eradication Initiative, Global Influenza Surveillance and Response System, and Global Poliovirus Laboratory Network models, providing confirmatory testing, genotyping, and molecular surveillance. Member laboratories adopt methods endorsed by World Health Organization and align with standards produced by institutions such as Centers for Disease Control and Prevention, National Institutes of Health, Public Health England, Institut Pasteur, and Robert Koch Institute. The MRLN supports elimination verification processes used by regional bodies including World Health Organization Regional Office for the Western Pacific, World Health Organization Regional Office for Europe, and World Health Organization Regional Office for South-East Asia.

Governance typically involves steering committees and technical advisory groups composed of representatives from agencies like World Health Organization, Centers for Disease Control and Prevention, Pan American Health Organization, Gavi, the Vaccine Alliance, and national ministries such as Ministry of Health (United Kingdom), Ministry of Health and Family Welfare (India), and Ministry of Health (Brazil). Legal and policy coordination draws on frameworks from multilateral instruments including International Health Regulations (2005) and intergovernmental mechanisms used by United Nations agencies. Funding and strategic oversight have engaged philanthropic and multilateral donors such as Bill & Melinda Gates Foundation, Global Fund, and regional development banks like Inter-American Development Bank. Technical governance is informed by advisory inputs from laboratories affiliated with Johns Hopkins University, London School of Hygiene & Tropical Medicine, Karolinska Institutet, and University of Oxford.

Reference laboratories provide confirmatory enzyme-linked immunosorbent assay testing, real-time polymerase chain reaction diagnostics, and viral genotyping using sequencing platforms pioneered at centers like Broad Institute, Wellcome Sanger Institute, and Max Planck Society laboratories. Activities include detection of measles IgM, rubella IgM, and molecular detection of measles virus and rubella virus genomes, with phylogenetic analyses informed by datasets hosted in repositories such as GenBank, GISAID, and European Nucleotide Archive. Field laboratories perform specimen collection aligned with protocols developed by World Health Organization and technical guidance from Centers for Disease Control and Prevention and Institut Pasteur. Collaborative projects have linked laboratories across networks involving African Union, European Union, ASEAN, and Mercosur partners for cross-border surveillance.

Quality assurance relies on external quality assessment schemes coordinated by reference institutions like Centers for Disease Control and Prevention, Public Health England, and Institut Pasteur, with proficiency testing distributed similarly to programs used by World Health Organization Global Laboratory Network. Accreditation pathways reference standards from International Organization for Standardization such as ISO 15189 and engage accreditation bodies including United Kingdom Accreditation Service and National Accreditation Board for Testing and Calibration Laboratories. Laboratories participate in interlaboratory comparison studies and implement quality management systems recommended by World Health Organization and professional societies like Clinical and Laboratory Standards Institute.

The network underpins case-based surveillance systems coordinated with ministries like Ministry of Health (Kenya), Ministry of Health (Nigeria), and Ministry of Health (Japan), contributing laboratory-confirmed case counts used by regional verification commissions such as Regional Verification Commission for Measles and Rubella Elimination (WHO) and national immunization technical advisory groups modeled on Advisory Committee on Immunization Practices. During outbreaks, laboratories support rapid diagnostic testing, contact tracing analytics similar to methods used in Ebola virus epidemic in West Africa responses, and genomic epidemiology linking to platforms developed by Nextstrain and bioinformatics groups at European Bioinformatics Institute. Data reporting flows through health information systems like District Health Information Software 2 and global reporting channels into World Health Organization surveillance databases.

Capacity building includes laboratory training courses run in partnership with academic centers such as London School of Hygiene & Tropical Medicine, Emory University, University of California, San Francisco, and regional training hubs hosted by African Field Epidemiology Network. Research collaborations have involved multicenter studies with institutes like Centers for Disease Control and Prevention, Institut Pasteur, and Karolinska Institutet investigating vaccine effectiveness, virus evolution, and diagnostic performance. Training emphasizes biosafety practices aligned with guidance from World Health Organization and Centers for Disease Control and Prevention and laboratory network development draws on lessons from Global Polio Eradication Initiative and Global Influenza Surveillance and Response System.

Challenges include sustaining financing amid shifting donor priorities from funders such as Gavi, the Vaccine Alliance and Bill & Melinda Gates Foundation, maintaining laboratory workforce retention in contexts like Sub-Saharan Africa and South Asia, and integrating genomic surveillance capacity comparable to initiatives at Wellcome Sanger Institute and Broad Institute. Future directions prioritize expanded sequencing, digital data integration with platforms like DHIS2 and Nextstrain, strengthened links to immunization programs in countries such as India, Nigeria, and Brazil, and enhanced collaboration with emerging public health consortia including Africa Centres for Disease Control and Prevention and regional WHO offices to support measles and rubella elimination goals endorsed by global health bodies including United Nations and World Health Assembly.
