Fight against polio

Description

In Nigeria, a decade ago, some leaders in the northern part of the country started the rumor that the polio vaccine reduced fertility in the children who received it. Campaigns were suspended for a year while officials disproved the allegations. A large epidemic sliced through Northern Nigeria, and polio spread back into about twenty nearby countries where it had been eliminated. All those countries had to ramp up again to win the fight for the second time. The rumors persisted even after the campaigns were restarted, and to this day some parents refuse to let their children be vaccinated
