UNICEF was created in 1946 by the United Nations to provide humanitarian aid to children. Over the decades, UNICEF has expanded its mission from focusing on child health to also addressing education, sanitation, and children's rights. Some of UNICEF's key impacts include helping reduce diseases through vaccination campaigns, improving lives through low-cost health interventions like oral rehydration therapy, and advocating on behalf of children affected by issues like HIV/AIDS. UNICEF continues its work with support from the UN and donations from governments and individuals worldwide.
