In China, during the National Immunization Days in 1993 and 1994, 80 million children were immunized twice with oral polio vaccine each time.

In the Philippines, rebel groups agreed to a ceasefire in 1993 and brought their children to be immunized on National Immunization Day.

The Philippines Department of Health and Rotary Club spent four months planning the logistics and organizing community action; about 80% of children in conflict-affected areas were reached.

In the Lao People's Democratic Republic, Mongolia and Papua New Guinea, volunteers had to travel on foot, on horseback and by boat to reach children in remote areas. Vaccines were packed in ice in cooler boxes to maintain their potency during transportation. Parents and children often travelled far distances to reach immunization stations once they had heard the news.
