Passage Five About 14,000 people will contract HIV today. And tomorrow and the day after that, and every day for the foreseeable future. That’s 5 million by the end of the year, most of whom will be dead within a decade. Figure like these bring home the devastating impact of AIDS and the Urgent need of for a cheap, effective vaccine. As a stroke, a vaccine could stop the tide of infection and stem the need for more, costly treatment. It could even help people who already have the virus healthy. Back in 1990, drugs companies and researchers confidently predicted we’d Have a vaccine against HIV-1 within 10 years. These were rash statement. The virus has turned out to be more cunning and stealthy than anyone expected. And our knowledge of how vaccine boister the immune system hasn’t been good enough.
