Child diseases on rise as COVID-19 slows routine vaccinations -U.N.

GENEVA, July 15 (Reuters) - Nearly 23 million children missed out on routine vaccinations last year due to the COVID-19 pandemic, the highest number in more than a decade, fuelling outbreaks of measles, polio and other preventable diseases, U.N. agencies said on Thursday.

Measles, one of the world's most contagious diseases, can be fatal to children under the age of five, especially in African and Asian countries with weak health systems, according to the World Health Organization. Polio can cripple a child for life.

The gap in global vaccination coverage has set up a "perfect storm", leaving more children vulnerable to infectious pathogens just as many countries ease COVID-19 restrictions, the WHO and U.N. Children's Fund said in an annual report.

Ten countries, led by India and Nigeria, account for the bulk of the 22.7 million children left unvaccinated or under-vaccinated against diphtheria, tetanus, and pertussis (DTP) in 2020 - 3.7 million more than in 2019 and the most since 2009, it said regarding a key indicator of childhood vaccination rates.

"Large and disruptive" outbreaks of measles have been recorded in hotspots including Afghanistan, Mali, Somalia and Yemen, the report added.

Some 22.3 million children missed their first dose of measles vaccine last year - although there was probably substantial overlap with those lacking DTP coverage - for the lowest coverage against the killer disease since 2010, it said.

"The COVID-19 pandemic has led to major backsliding on childhood vaccination, taking us back more than a decade," Kate O'Brien, WHO director of immunisation, told a news briefing. ...
