In 1978, The Rotary Foundation launched its most comprehensive humanitarian service activity with the Health, Hunger and Humanity Grants program. The "3-H" Grants program is designed to undertake large-scale service projects beyond the capacity of individual Rotary clubs or groups of clubs.

Since 1978, almost 290 3-H projects have been carried out in 75 countries, with an appropriation of more than $74 million. The objective of these projects is to improve health, alleviate hunger, and enhance human, cultural, and social development among peoples of the world. The ultimate goal is to advance international understanding, goodwill, and peace.                                   

The first 3-H project was the immunization of six million children in the Philippines against polio, marking the birth of what we now know as the PolioPlus program. As 3-H progressed, new projects, including nutrition programs, vocational education initiatives, food production enhancement, and polio victim rehabilitation, were carried out to help people in developing areas of the world. All 3-H projects are supported by the voluntary contributions of Rotarians through The Rotary Foundation.
