Millions of children worldwide have been left vulnerable to preventable diseases, including measles, polio, tetanus and tuberculosis
That's according to a new ysis published on Tuesday in the medical journal The Lancet
It found that life-saving vaccination efforts have stalled or reversed since 2010 amid persistent health inequalities, misinformation and hesitancy
Child health experts are warning that cuts to international aid budgets funding vaccination programs combined with vaccine skepticism are creating a perfect storm
The report's authors say progress in rolling out jabs over the past five decades has prevented the deaths of 154 million children
But by 2023, nearly 16 million had not had any childhood vaccinations, most of them in sub-Saharan Africa and South Asia
They're calling for a concerted effort to provide better and more equal access to vaccines
saying routine childhood jabs are one of the most cost-effective public health interventions
