Four decades since AIDS epidemic began, but still no vaccine
France24 says Covid vaccines began to show promise just months after the novel coronavirus started spreading across the globe. So why have decades of HIV/AIDS research yielded so little progress on a jab to prevent a disease that claimed some 680,000 lives in 2020?
As the globe marks World AIDS Day on Wednesday, why is there still no vaccine to protect people from the Human Immunodeficiency Virus (HIV)?
One answer is that the political will and colossal investment that have spurred on Covid vaccine development have largely been missing from AIDS vaccine research since HIV was discovered in 1983.
