Shaw’s research team showed that WHO and Rockefeller Foundation scientists began research on “anti-fertility” vaccines for “birth-control” as early as 1972, by lacing hCG with tetanus toxoid, which acts as a carrier for the hormone. That year, WHO researchers at a meeting of the US National Academy of Sciences109, 110 reported their successful creation of a “birth-control” vaccine that diminishes the βhCG essential to a successful pregnancy and causes at least temporary “infertility.” Subsequent experiments proved that repeated doses could extend infertility indefinitely.
