1. Reaching the most vulnerable Around the world, it is children who are most in need – of health care, adequate nutrition, education, protection. Children who live in remote locations or in poverty, who are discriminated against or marginalized for whatever reasons, or who are simply vulnerable as a result of natural disasters or conflict situations can be the hardest to reach. These children must be reached wherever they are, because investing in the most disadvantaged children yields some of the most lasting rewards. These photographs depict what disparities can look like up close and how efforts are making a difference.

7. In Mindanao, the Philippines, access to safe drinking water protects a girls health. The country will likely achieve the part of the Millennium Development Goal for providing safe water – but not in all regions. Two thirds of families in Mindanao are still without it. © UNICEF/PHIA2010-0002/Dragaj

8. Haiti is one of the worlds poorest countries and, as such, among the least equipped to recover from natural disasters. A year after the 2010 earthquake, UNICEF continued to treat undernourished children, helping to prevent an increase in acute malnutrition cases. © UNICEF/NYHQ2010-2612/LeMoyne

10. Children in some countries, such as Angola, continue to miss out on the series of vaccinations needed to fully protect them from diseases. Young Georgina, whose legs are paralysed by polio, is one of those children. Vaccines are highly cost-effective health investments that could save 2 million lives a year globally if they reached all children. © UNICEF Angola/2010/ Williams

Unsafe behaviour, which, among other things, puts adolescents at risk of contracting HIV, accounted for more than 40 per cent of new infections around the world in 2009 among people older than 15 years old.
