"We're going to learn different strategies about how we can attack the viral reservoir, how we can harness the immune system better and what exactly caused the lack of virus in the two patients at least in the short term."
Earlier this year, researchers said an HIV-positive baby in Mississippi was given high doses of three antiretroviral drugs within 30 hours of her birth, with doctors hoping that would control the virus.
Two years later, there is no sign of HIV in the child's blood, making her the first child to be "functionally cured" of HIV.
The Foundation for AIDS Research, or amfAR, helped fund the study.
"These findings clearly provide important new information that might well alter the current thinking about HIV and gene therapy," said amfAR CEO Kevin Robert Frost.
"While stem cell transplantation is not a viable option for people with HIV on a broad scale because of its costs and complexity, these new cases could lead us to new approaches to treating, and ultimately even eradicating, HIV."
"Dr. Henrich is charting new territory in HIV eradication research," said Dr. Rowena Johnston, amfAR vice president and director of research.
"Whatever the outcome, we will have learned more about what it will take to cure HIV. We believe amfAR's continued investments in HIV cure-based research are beginning to show real results and will ultimately lead us to a cure in our lifetime."
In the meantime, Henrich says he and other groups are actively enrolling patients for these types of studies.
