The "Give Every Child a Future" project is the major international focus of civil society group Rotary as it celebrates 100 years of service in New Zealand, Australia and the Pacific.
Rotary will partner with the United Nations children's agency UNICEF to support the introduction of three vaccines in the region.
Vathinee Jitjaturunt of UNICEF Pacific said the vaccines targeted three diseases.
"This project I think it will be able to prevent diarrhoea, pneumonia and cervical cancer. These three diseases are high in the Pacific."
