3. HIV Vaccine
Between 1983 (when HIV was first characterised) and the early 2010s, the HIV/AIDS virus had claimed the lives of over 35 million people around the world. Many millions of people still live with the virus. A workable HIV vaccine, therefore, is seen by many as a medical holy grail. Continued trials of a vaccine which came about in 2012 are thankfully leading us closer and closer towards that holy grail.
The 2012 vaccine, known as SAV001, showed success in animal subjects and began its first phase of human clinical trials in Canada. The vaccine was administered to infected men and women aged 18 to 50 – with positive results. The patients experienced no side effects or reactions to the injection and even displayed a boost in immunity. The vaccine has since progressed to phases 2 and 3 with similarly positive results. It is hoped that the vaccine will become commercially available in 2017.
