‘Question of time’: health experts warn of imminent measles outbreak in Balkans

— Despite vaccinating her first child, Vanja drew a line when it came time to inoculate her second and decided he would not be receiving the measles shot.

The 44-year-old psychologist living in Montenegro’s capital Podgorica gave a host of reasons why she changed her mind, all after binging on a deluge of information shared in an online group she belongs to.

“I don’t trust the vaccination system. We lack information and education,” Vanja told AFP, asking that her surname be withheld.

“I feel great responsibility and it wasn’t a simple and easy decision to make.” Vanja’s position is increasingly common in Montenegro which has the lowest measles vaccine uptake globally with just 23.8 percent of infants inoculated in 2020 with the first of two shots, according to World Health Organization data.

The dramatic decline in inoculation rates has public health experts bracing for an imminent measles outbreak in Montenegro and its nearby Balkan neighbors where vaccination uptake has also plummeted, largely due to a rise in misinformation, especially during the Covid-19 pandemic.

“The risk of a measles outbreak is high,” Dragan Jankovic, an immunisation official with the WHO, told AFP.

“Importation of the measles virus is only a question of time… as soon as it is imported into a susceptible population, an outbreak will start.”

In neighboring North Macedonia, 63 percent of children were inoculated with the first shot of the combined measles, mumps and rubella (MMR) vaccine, while in Serbia 78 percent have had the jab.

‘Perfect storm’

Experts say a uptake of at least 95 percent of the two-dose jab is needed to avoid the spread of measles, a highly contagious airborne disease that can be fatal.

The virus can cause complications that include blindness, brain swelling and pneumonia, and unvaccinated children are at the highest risk of developing serious cases — including death.

But for decades, there has been an aversion to the MMR shot, rooted in rampant misinformation tied to a widely debunked 1998 study that suggested a link between autism and the vaccine.

The United Nations has repeatedly warned that a “perfect storm” was brewing for new outbreaks of preventable diseases, with the pandemic disrupting routine vaccinations.

And even after the measles killed over 207,000 people worldwide in 2019, vaccination rates still dropped in many parts of the globe.

The first-dose vaccination rate dropped from 86 to 84 percent globally between 2019 and 2020, while only 70 percent received a second dose during the same period, according to WHO data.

In the Balkans, epidemiologists chalk up the growing anti-vax sentiment to several factors, including distrust in the government, a lack of serious enforcement measures, and a deluge of misinformation that overwhelmed social media during the pandemic.

In Montenegro, doctors have called on the government to take the issue more seriously, saying small fines on parents who refuse mandatory vaccine mandates have done little to reverse the country’s anti-vax shift.

“The MMR vaccine is currently not a condition for enrollment in schools and kindergartens,” Milena Popovic Samardzic, an epidemiologist from Montenegro’s Institute of Public Health, told AFP.

Almost one-third of Montenegrins believe a conspiracy theory that alleges doctors and government seek to vaccinate children with shots that cause autism, according to an Ipsos survey published in 2021.
