Landmark study results published in 2010 showed that the drug, made by California-based Gilead Sciences, helped ward off HIV in healthy gay men who engage in risky sex behaviors by 44 to nearly 73 per cent. But critics note that the pill is costly -- up to USD 14,000 per year -- and some warn that the clinical trial did not represent real-world circumstances and could lead to a spike in unprotected sex and a new surge in AIDS cases.u00a0
