Scientists have been trying for decades to develop an HIV vaccine. After a Merck vaccine failed to prove effective in 2007, researchers looked back at the data and found it raised the risk of people developing the disease. Hopes were buoyed by a 2009 study in Thailand, which showed limited but significant efficacy, reducing the rate of infection by about 30%. But last year, an effort combining vaccines from Sanofi and GlaxoSmithKline also failed to prove effective.
