2019 edition of World Polio Day (WPD)
The World Polio Day (WPD) is observed every year on 24th October by the World Health Organization (WHO) and its allied agencies to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine against poliomyelitis. The day provides an opportunity to celebrate progress towards a polio-free world and the tireless efforts of many towards the goal.
