That same wariness may well have carried over to the measles-rubella jab, with many parents simply refusing to let their children be vaccinated.

Measles has its own set of drivers, too. Poverty, education levels, and how often mothers attend antenatal check-ups all shape whether children in a community end up vaccinated. Add it all up, and childhood vaccination coverage has been sliding for years – down to just 87%.
