World AIDS Vaccine Day History

The first idea to celebrate World AIDS Vaccine Day came with the commencement speech at Morgan State University made by the then-President of the United States Bill Clinton on May 18, 1997. In his speech, the President challenged the world in the emerging age of science and technology to set new goals for HIV prevention and develop an AIDS vaccine within the next decade. Inspired by the speech, America started the world’s first AIDS Vaccine Day which was observed one year later on May 18, 1998.
