Data analyses in molecular biology and phylogenetic studies contradict the OPV AIDS hypothesis; consequently, scientific consensus regards the hypothesis as disproven. The journal "Nature" has described the hypothesis as "refuted". Two vaccines are used throughout the world to combat poliomyelitis. The first polio vaccine, developed by Jonas Salk, is an "inactivated poliovirus vaccine" (IPV), consisting of a

Author and journalist Howard Taubman explained: "The New York Times", in a 1980 article celebrating the 25th anniversary of the Salk vaccine, described the current workings at the facility: At the institute, a magnificent complex of laboratories and study
