World AIDS Vaccine Day

World AIDS Vaccine Day symbolizes hope that one day the disease will be prevented and eradicated. The event is informational in nature, with organizations hosting various activities to draw public attention to the importance of developing an AIDS vaccine.

History

World AIDS Vaccine Day has been observed since 1998. The previous year, in 1997, President Bill Clinton delivered a speech to graduates of Morgan State University, where he encouraged them to pursue new discoveries, including the development of a vaccine against the human immunodeficiency virus (HIV), with the goal of eradicating this global threat.

Clinton’s speech was delivered on May 18, which was chosen as the date for World AIDS Vaccine Day. Information and educational conferences are held both online and offline, with participants often wearing a red ribbon — the global symbol of the fight against AIDS. On this day, organizations raise awareness about the need to invest in vaccine development, and gratitude is expressed to those working toward the production of a safe and effective AIDS treatment.
