20 million children miss out on DPT vaccines in 2018

20 million children miss out on DPT vaccines in 2018

As many as 20 million children worldwide, which amounts to more than 1 in every 10 children, missed out on lifesaving vaccines such as measles, diphtheria and tetanus in 2018, according to new data from WHO and UNICEF.

Globally vaccination coverage with three doses of diphtheria, tetanus and pertussis (DTP3) and one dose of the measles vaccine has stalled at around 86 percent, since 2010.

The world bodies are of the view that 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 the 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 marginalized, those touched by conflict or forced from their homes – who are persistently missed,” he pointed out in a statement.

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, Democratic Republic of the Congo (DRC), 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.

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.

Ukraine leads 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.

HPV vaccine coverage

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 had introduced the HPV vaccine into their national programmes. Just 13 of these are lower-income countries, according to the release.

WHO and UNICEF jointly produce national immunisation coverage estimates for member states on an annual basis.

DTP3 coverage is used as an indicator to assess the proportion of children vaccinated and is calculated for children under one year of age. The estimated number of vaccinated children are calculated using population data provided by the 2019 World Population Prospects (WPP) from the UN.
