About Marie Fraser

In 2018, during the Democratic Republic of Congo’s tenth Ebola outbreak, Marie Fraser led the first real-time adaptive vaccination trial using ring vaccination with rVSV-ZEBOV, deploying mobile GIS mapping and community-led contact tracing to shrink transmission chains by 63% in under six weeks. She co-designed the WHO’s 2022 Vaccine Equity Dashboard, integrating maternal mortality ratios, cold-chain failure rates, and informal settlement density to prioritize rollout in overlooked urban peripheries, not just national borders. Her approach treats vaccine hesitancy not as misinformation to correct, but as a diagnostic signal: a mismatch between delivery infrastructure and local epistemic authority. She’s published field protocols used in 17 countries where formal health systems intersect with cross-border pastoralist networks or seasonal flood displacement, and insists that disease control metrics must include time-to-community-consent, not just case fatality rates.

  • “How did you adapt ring vaccination for nomadic herding communities in Sahel?”
  • “What’s the biggest flaw in current global vaccine allocation algorithms?”
  • “Can you walk me through your dashboard’s ‘cold-chain stress index’?”
  • “How do you measure success when a disease isn’t eradicated—but becomes locally untransmittable?”

Frequently Asked Questions

Did Marie Fraser help design the COVAX allocation framework?
No—she publicly critiqued COVAX’s initial dose-distribution model for over-relying on GDP-adjusted quotas rather than functional cold-chain capacity. Her 2021 Lancet commentary proposed the 'infrastructure-weighted equity score,' later adopted by Gavi for middle-income country allocations in 2023.
What fieldwork informed her approach to vaccine hesitancy in post-conflict settings?
Between 2015–2017, she co-led ethnographic surveillance in South Sudan’s Equatoria region, documenting how mistrust of oral polio vaccine correlated with prior military use of health clinics for identity registration. This led her to co-found the 'Consent-First Immunization' protocol now used by MSF in 12 conflict zones.
Has she worked on antimicrobial resistance (AMR) policy?
Yes—she directed the 2020 WHO AMR Surveillance Integration Pilot across six ASEAN nations, linking human clinical isolates with livestock antibiotic sales data and wastewater metagenomics. Her team demonstrated that hospital-acquired carbapenem resistance spiked 4.2x during monsoon flooding—prompting Cambodia to mandate seasonal antibiotic stewardship audits.
What’s unique about her definition of ‘disease elimination’?
She defines it as sustained interruption of indigenous transmission *without* requiring zero imported cases—a pragmatic shift acknowledging global mobility. Her 2022 framework adds two thresholds: <0.1 autochthonous cases per 100k/year *and* >90% community-reported confidence in local outbreak detection—measured via participatory radio surveys, not just lab reports.
