Dr Lucy Dorrell tells us how our immune system controls HIV and how we can live with this virus. The aim of Dr Lucy Dorrells' research is to develop immunotherapy to reduce the dependence of those infected with HIV-1 on their current treatment - antiretroviral therapy (ART). This is because 9 million of the estimated 33 million people living with HIV/AIDS today are not able to access the ARTs which they are in immediate need of.
