They used to use a vaccine which caused Polio by itself, after a child have been vaccinated they could spread Polio to those around them via shedding.
"Jonas Salk, inventor of the IPV, testified before a Senate subcommittee that nearly all polio outbreaks since 1961 were caused by the oral polio vaccine."
Bill Gates still sends that particular vaccine to the Third World.
