Despite the stagnating vaccination rates, more than 140,000 already died because of measles.

The World Health Organization (WHO) and the United States Centers for Diseases Control and Prevention (CDC) on Thursday said over 140,000 individuals worldwide already died from measles despite the vaccination rates that have stagnated for nearly a decade. 

Poorer countries were hardest hit, with the vast majority of measles cases and deaths in sub-Saharan Africa. However, wealthier countries, have also been battling their own outbreaks, with four European nations losing their “eliminated” status in 2018.

The announcement came as the Pacific island nation of Samoa was locked down in order to carry out a mass vaccination campaign to cope with an epidemic that has killed 62 and, according to UN officials, was fuelled by anti-vaxxer conspiracy theories on the internet.

“The fact that any child dies from a vaccine-preventable disease like measles is frankly an outrage and a collective failure to protect the world’s most vulnerable children,” WHO director-general Tedros Adhanom Ghebreysus said.

“To save lives, we must ensure everyone can benefit from vaccines, which means investing in immunization and quality health care as a right for all,” he added.

Majority of the deaths occurred among children under five years old. Babies and infants are at greatest risk of infection and of developing complications, including pneumonia and brain swelling that can lead to permanent damage, blindness or hearing loss.

Around 142,300 people lost their lives to the disease in 2018 — a quarter of the number of deaths in 2000, but up by 15% compared to 2017. There were 9.7 million total cases.

The WHO and UNICEF estimated that 86 percent of children globally received the first dose of measles vaccine in 2018, but fewer than 70 percent received the second recommended dose.

That is far short of the recommended 95 percent vaccination coverage with two doses of measles vaccine deemed necessary to protect populations from the disease.

The five worst affected countries, Democratic Republic of the Congo (DRC), Liberia, Madagascar, Somalia and Ukraine, accounted for half of all cases worldwide.

However, the US also saw its highest number of cases in 25 years, barely avoiding losing its status of having eliminated the disease. The status is lost if an outbreak is sustained continuously for more than a year.

On the other hand, Albania, the Czech Republic, Greece and the United Kingdom all lost their eliminated status.

The increase comes as a growing anti-vaccine movement became popular around the world, driven by fraudulent claims linking the MMR vaccine against measles, mumps and rubella to a risk of autism in children.

Meanwhile, a recent study showed that contracting the measles virus decimated the protective antibodies responsible for remembering previous encounters with disease: effectively wiping the host’s immunity memory.
