UNICEF USAThis little blue box helps save children's lives. 💙 It's called a vaccine cold box, and it's essential to getting vaccines safely to children in even the hardest-to-reach places. During #WorldImmunizationWeek, we're celebrating the people, tools and technology that help ensure no child is left behind. UNICEF procures cold chain equipment and works with partners and governments around the world to keep the vaccine cold chain unbroken — because vaccines only work when they reach the children who need them. #VaccinesWork. And so do the people delivering them.
