The number of measles deaths in children skyrocketed last year largely because of funding cuts for relatively affordable vaccines, the World Health Organization (WHO) announced on Thursday.

According to WHO, 145,700 kids succumbed to the highly contagious virus last year, a 19 percent jump from 2012. This concerning setback could mean that the goal to nearly put an end to measles deaths in the next year may not be met, the organization said.

The Measles & Rubella Initiative, a global partnership that includes the American Red Cross and UNICEF, had been making encouraging progress in disseminating vaccines and decreasing measles deaths. Since 2000, some 1.7 billion children have been vaccinated and the group hoped to reduce measles deaths by 95 percent by next year.

But because governments and partners have slashed funding, vaccine campaigns have been postponed -- leading to large outbreaks in a number of countries, according to Robert Kezaala, UNICEF’s senior health advisor for immunization.

It costs about $1 to vaccinate a child against measles in the developing world. But neglecting to do so can cause immeasurable harm.

Children who aren’t vaccinated are at risk for such health complications as pneumonia, brain, damage and blindness, according to UNICEF.

An estimated 21.5 million children weren’t vaccinated last year and more than 60 percent of these kids reside in a handful of countries, including India, Pakistan and Nigeria.

The Measles & Rubella Initiative has warned that the only way to get back on track to eliminating the virus is by raising awareness about the disease’s effects, increasing funding and supporting vaccine campaigns.
