Efforts by Dunfermline litter pickers will help vaccinate 450 children against poliovirus.
Members of the Carnegie Dunfermline Rotary Club and Touch Community Garden supporters walked a mile around Touch for End Polio Now on World Polio Day.
They picked up litter along the way, raising £350 through donations and sponsorships.
This will be tripled to £1,050 by the Bill & Melinda Gates Foundation, who add £2 for every pound raised by Rotary.
Carnegie Dunfermline Rotary Club president, Charlie Clark, said: "Polio is an awful disease.
"I can remember a school friend struggling to get around with a horrible caliper on her paralysed leg because vaccination came just too late for her, so I know how important it is to keep up the effort against it.
"Until vaccination became available in the 1950s, polio killed thousands of people, and blighted the lives of millions of others.
"Thousands suffered right here in Scotland."
Mr Clark said: "This demonstrates how essential it is to keep up the vaccination programme.
"Rotary and its partners won’t rest until we’ve wiped the virus from the face of the earth."
