A new antiretroviral injection tested on monkeys has shown to be 100% effective for up to a month in respect to HIV.
Researchers at Columbia University’s Mailman School of Public Health have found that an injection of antiretroviral drugs can give 100 percent protection from HIV.
Although the two monkey trials revealed protection against HIV for a month, the New York Times reports that this could be up to 3 months in humans.
The advantage of an injection regime every three months would of course have a greater benefits over a daily regime of taking pills. Inconsistency in a schedule of taking pills can and have lead to resistance to certain medications reducing medication options for those living with HIV. An injection would reduce this risk, as the subject would only require an injection once every three months, that is 4 times a year, to have full protection against HIV. Taking an injection late would possibly not have the same consequences, and could easily be incorporated in to the patients regular visit to the clinic.
The treatment would be of greatest benefit to serodiscordant couples — where one person is HIV-positive and the other is HIV-negative.
Dr Wafaa El-Sadr, an AIDS expert at Colombia, tells the Times that a preliminary human trial is set to start later this year. A larger trial that could lead to widespread usage is still a number of years away.
