Polio vaccine incidents reduced public confidence in polio vaccine leading to a drop in vaccination rates. At the same time that Salk was testing his vaccine, both Albert Sabin and Hilary Koprowski continued working on developing a vaccine using live virus. During a meeting in Stockholm to discuss polio vaccines in November 1955, Sabin presented results obtained on a group of 80 volunteers, while Koprowski read a paper detailing the findings of a trial enrolling 150 people. Sabin and Koprowski both eventually succeeded in developing vaccines. Because of the commitment to the Salk vaccine in America, Sabin and Koprowski both did their

Sabin is currently working on multiple vaccines for humans including vaccines for Hookworm infection ("Na"-GST-1, "Na"-APR-1), Schistosomiasis ("Sm"-TSP-2), Chagas disease ("Tc"24, TSA-1), Leishmaniasis ("Ld"-NH36, PdSP15), Severe acute respiratory syndrome (SARS)/Middle East respiratory syndrome (MERS) (Pan-β-CoVax), Soil-transmitted helminthiasis (STH), and Onchocerciasis (Ov-"103", Ov-"RAL-2"). In 2006, Sabin co-founded the Global Network for Neglected Tropical Diseases in order "to raise the awareness, political will and funding necessary to control and eliminate the most common NTDs." Through its work on NTDs, Sabin hopes to reduce poverty caused by these diseases as many of them have been shown to adversely affect
