20m children miss out on lifesaving measles, diphtheria and tetanus vaccines in 2018
Some 20 million children worldwide – more than 1 in 10 – missed out on life-saving vaccines such as measles, diphtheria, and tetanus in 2018, according to new data from World Health Organisation, WHO, and United Nations International Children's Emergency Fund, UNICEF.
Globally, since 2010, vaccination coverage with three doses of diphtheria, tetanus, and pertussis (DTP3) and one dose of the measles vaccine has stalled at around 86 percent. While high, this is not sufficient. 95 percent coverage is needed – globally, across countries, and communities - to protect against outbreaks of vaccine-preventable diseases.
"Vaccines are one of our most important tools for preventing outbreaks and keeping the world safe," said Dr. Tedros Adhanom Ghebreyesus, Director-General of WHO. "While most children today are being vaccinated, far too many are left behind. Unacceptably, it’s often those who are most at risk– the poorest, the most marginalised, those touched by conflict or forced from their homes - who are persistently missed."
Most unvaccinated children live in the poorest countries and are disproportionately in fragile or conflict-affected states. Almost half are in just 16 countries - Afghanistan, the Central African Republic, Chad, the Democratic Republic of the Congo, Ethiopia, Haiti, Iraq, Mali, Niger, Nigeria, Pakistan, Somalia, South Sudan, Sudan, Syria, and Yemen.
If these children do get sick, they are at risk of the severest health consequences, and least likely to access lifesaving treatment and care.
Measles outbreaks reveal entrenched gaps in coverage, often over many years.
Stark disparities in vaccine access persist across and within countries of all income levels. This has resulted in devastating measles outbreaks in many parts of the world – including countries that have high overall vaccination rates.
In 2018, almost 350,000 measles cases were reported globally, more than doubling from 2017.
"Measles is a real-time indicator of where we have more work to do to fight preventable diseases," said Henrietta Fore, UNICEF’s Executive Director. "Because measles is so contagious, an outbreak points to communities that are missing out on vaccines due to access, costs or, in some places, complacency. We have to exhaust every effort to immunize every child."
Ukraine leads a varied list of countries with the highest reported incidence rate of measles in 2018. While the country has now managed to vaccinate over 90 percent of its infants, coverage had been low for several years, leaving a large number of older children and adults at risk.
Several other countries with high incidence and high coverage have significant groups of people who have missed the measles vaccine in the past. This shows how low coverage over time or discrete communities of unvaccinated people can spark deadly outbreaks.
For the first time, there is also data on the coverage of human papillomavirus (HPV) vaccine, which protects girls against cervical cancer later in life. As of 2018, 90 countries – home to 1 in 3 girls worldwide - had introduced the HPV vaccine into their national programmes. Just 13 of these are lower-income countries. This leaves those most at risk of the devastating impacts of cervical cancer still least likely to have access to the vaccine.
Together with partners like Gavi, the Vaccine Alliance, WHO and UNICEF are supporting countries to strengthen their immunisation systems and outbreak response, including by vaccinating all children with routine immunisation, conducting emergency campaigns, and training and equipping health workers as an essential part of quality primary healthcare.
