Decline blamed on health inequalities, COVID disruption and soaring levels of misinformation and hesitancy

Millions of children worldwide are at risk of lethal diseases because vaccine coverage has stalled or reversed amid persistent health inequalities and soaring levels of misinformation and hesitancy, the largest study of its kind has found.

Major progress in rolling out jabs to billions of children in all corners of the globe over the last five decades has prevented the deaths of 154 million children, according to an analysis published in the Lancet.

But since 2010, progress has stalled or reversed in many countries. Measles vaccination rates have fallen in 100 of 204 countries, while coverage for at least one dose against diphtheria, tetanus, whooping cough, measles, polio or tuberculosis has declined in 21 of 36 high-income countries – including France, Italy, Japan, the UK and the US.

The reversal, further exacerbated by the disruption caused by the Covid-19 pandemic, has left millions of children vulnerable to preventable diseases and death, the authors of the study led by the University of Washington in Seattle said.
