“I love to travel in rural areas,” Peta says. “It’s both rewarding and fun to help people here.”
Each time Peta visits the distant towns, she carries an insulated box to keep measles and rubella vaccines at a constant temperature. If at any stage the vaccine’s temperature drops below two degrees or rises above eight, it can become unusable.
It’s not an easy job, but Peta never gives up.
Thanks to healthcare staff like Peta, children of nomadic herder families - roughly a quarter of Mongolia’s children - have been immunised against deadly measles and rubella.
Despite the incredible progress, there are still 20 million children around the world that don’t receive even the most basic vaccines, leaving them vulnerable to disease.
