Prior state
COVID-era disruptions had left measles and DTP coverage below 2019 levels in many lower-income settings; outbreaks continued in under-vaccinated pockets.
Material change
By the close of 2028, administrative and survey data show that a majority of monitored low- and lower-middle-income countries have restored or surpassed their 2019 coverage rates for measles-containing vaccine and the third dose of diphtheria-tetanus-pertussis vaccine.
Why now
Multi-year catch-up campaigns funded through 2025–2027 replenishments, combined with restored primary-care outreach after other health-system shocks, produce measurable recovery by 2028 rather than earlier or later.
Mechanism and resistance
Intensified outreach, mobile teams, and integration with other child-health contacts drive coverage. Resistance appears in conflict-affected districts, vaccine hesitancy clusters, and health-workforce attrition.
Consequences
Measles outbreak frequency declines in recovering countries. Health ministries reclaim political credit; remaining zero-dose communities become more visible targets for subsequent campaigns. Donor attention begins to shift toward sustaining rather than restoring coverage.
End state
More than half of the countries in the WHO/UNICEF monitoring set for low- and lower-middle-income status report coverage at or above 2019 levels for the two tracer antigens.
Observable test
WHO/UNICEF joint reporting or equivalent survey data confirming the majority threshold for the defined country set.
Disconfirming sign
Coverage remains below 2019 levels in a majority of the monitored set or large outbreaks continue at prior intensity.
