More than half a million children in the United Kingdom did not receive a key mask shock from UNICEF between 201
It comes when NHS leader Simon Stevens warned that measles cases quadrupled in England in just one year and prompted families to get the vaccine.
He said people rejected vaccines "Public Health Time Bomb".
Worldwide, the report said, 169 million children were not given the first measles vaccine between 2010 and 2017.
Measles are a highly contagious viral disease that can lead to serious health complications, including lung and brain infections, and is sometimes fatal.
Health experts say children should receive two doses of vaccine to fully protect themselves against the disease.
However, according to Unicef, dissatisfaction, misinformation, skepticism about vaccines, and inadequate access to jabs have led to inadequate vaccination coverage worldwide.
The most recent report shows that between 2010 and 2017:
- The US lists the unvaccinated in children High-income countries where 2,593,000 lost the first vaccine dose
- The Comparative figure for France was 600,000  The United Kingdom ranked third on the list of high-income countries, with 527,000 children not receiving the first dose of the vaccine over the seven-year period.
- In Nigeria, four million children under one child did not receive the first vaccine dose.
- In India there were 2.9 million.
Global numbers for the second dose of measles vaccine "were even more alarming," Unicef said.
The report found that 20 countries in Sub-Saharan Africa had not introduced the second dose, causing more than 17 million infants each year to be at higher risk of getting measles than the child.
& # 39; wake-up call & # 39;
Henrietta Fore, CEO of Unicef, said: "The measles virus will always find unvaccinated children."
"If we are serious about averting the spread of this dangerous but preventable disease to vaccinate poor countries.
Prof Beate Kampmann of the London School of Hygiene and Tropical Medicine described the numbers as a "wake up call."
She said, "One thing is for sure: a single person with measles can infect 90 other people who are not immune ,
"Measles are highly contagious, even before the typical rash occurs, so you can not just" stay away. "
" We need to protect children and communities from this potentially very serious but completely preventable infectious disease – and just do it Do this by vaccination.
Public Health England said that although the general public's risk in the UK was low, unimmunized people threatened to get the disease while the outbreaks persisted in Europe. This year, the disease has been hit hardest by the disease so far , Tens of thousands of cases were reported per million people.
Outbreaks also occurred in Brazil, Pakistan and Yemen, while case numbers increased in the US and Thailand.
