History of World AIDS Vaccine Day
The story of this day begins on 18 May 1997 . On that day, former US President Bill Clinton gave a speech at Morgan State University. He stressed the urgent need for a preventive HIV vaccine. He said that only a truly effective vaccine could greatly reduce and eventually end the threat of AIDS.
That speech started a global awareness movement. The first official World AIDS Vaccine Day was observed on 18 May 1998 . Since then, the day has been marked every year.
Why This Day Is Important
Raising Public Awareness
Many people think HIV is no longer a serious problem because treatments exist. But that is not true. HIV still affects millions of people around the world. This day reminds everyone that prevention is still very important.
Honouring Scientific Efforts
Developing an HIV vaccine is one of the hardest scientific challenges. Researchers have spent decades working toward this goal. This day recognises their dedication and hard work.
