In Brazzaville, Congo's capital, UNICEF UK Ambassador Ewan McGregor

 In Brazzaville, Congo's capital, UNICEF UK Ambassador Ewan McGregor poses with one of the city's 'Sapeurs', who are determined to overcome their surroundings through the power of sharp suits.

Ewan was in the Republic of Congo with us to see how we deliver vaccines to vulnerable children in some of the world’s remotest locations - the ‘Cold Chain’. We’re the biggest distributor of vaccines to the developing world, supplying vaccines for more than half the world's children in over 190 countries.
