The Canadian government allowed the doctors to prescribe a drug, that can prevent the transmission of HIV. Making the revolutionary drug affordable will be the next step.

The once-daily pill, which contains two anti-HIV drugs is approved in Canada to eliminate the risk of sexual transmission of the HIV virus, the Gilead Sciences Canada announced on Monday.

According to the study, the patients could virtually reduce their chances of contracting the virus, by taking one tablet daily. If it is taken correctly, the treatment could eliminate the risk of transmission by as much as 99 percent. Truvada, as one of the drugs, which make up the antiretroviral drug cocktail. It is one of the most effective drugs prescribed to manage HIV.

Norbert Bischofberger, the  chief executive vice-president of research and development of the Gilead Sciences Canada,  said that, "we are pleased to offer this important HIV prevention tool to at-risk populations in Canada."

“Truvada is very good at reducing risk, but it costs money. This has been a very exciting and important development," he added.

Sean Hosein of Canada's Source for HIV and HEP C Information, or CATIE, said that, taking medicines to decrease the risk of infection in HIV-negative people is called pre-exposure prophylaxis or PrEP.

"To facilitate access, private insurance companies need to move swiftly to add Truvada (when used as PrEP) to their list of reimbursed medicinesl. However, not everyone at high risk for HIV has private insurance. Canada's provinces and territories now need to consider adding PrEP to their lists of subsidized medicines," CATIE said.
