🛡️ When Should We Conduct a Measles-Rubella Vaccination Campaign? (Latest WHO Global Guidance) 🌍 GIS can be the game changer!
As a Surveillance & Immunization Medical Officer, I often get asked:
❓ “When is the right time for a Measles-Rubella (MR) campaign?”
Here’s my field-tested, WHO-aligned answer—plus a new infographic for practitioners and policymakers.
⬇️ Technical Decision Flow (With References):
➡️ Routine & Programmatic Triggers
🔹 Immunity gap ≥ annual birth cohort
📊 Susceptible children (missed by routine, SIAs, new births) ≥ 1 birth cohort
➡️ Mass SIA📑 (WHO SIA Field Guide, 2023)
🔹 Routine MR/MCV coverage <90%
📉 Coverage <90% nationally/subnationally
➡️ Follow-up SIA every 2–4 years📑 (CDC Global Immunization; WHO SIA Field Guide 2023)
🔹 MR/rubella vaccine introduction
🆕 New vaccine launched
➡️ Wide-age catch-up SIA (9mo–14y) (WHO Position Paper, 2020)
🔹 Service disruption (pandemic, conflict, crisis)
🚨 Coverage drops or missed doses accumulate
➡️ Catch-up SIA📑 (Immunization Agenda 2030, 2021)
➡️ Surveillance-Guided Triggers
🔹 Lab-confirmed outbreak or cluster
🧪 Outbreak detected
➡️ Outbreak Response Immunization (ORI) (WHO Measles Outbreak Toolkit, 2019)
🔹 Surveillance data: age shift/hidden gaps
👥 Cases in older children/adults or vaccinated cohorts
➡️ Targeted/wide-age SIA (PAHO TAG Recommendations, 2024)
🔹 Community/Sentinel Surveillance: Rash illness reports
👁️🗨️ Rash/fever clusters in community/sentinel sites
➡️ Local SIA or ORI (WHO Measles Surveillance Manual, 2018)
🔹 Serosurvey/modeling: ≥10% susceptible
📈 ≥10% non-immune in key age groups
➡️ Targeted SIA (CDC Measles-Rubella Elimination Guidance, 2023)
🔹 Surveillance indicators not met
⚠️ case detection below target: Non-Measles/Non-Rubella rate is low

As immunization professionals, our campaigns must always be:
✔️ Data-driven
✔️ Timely
✔️ Responsive to local surveillance
✔️ Rooted in WHO/CDC/PAHO/UNICEF/NITAG technical guidance
