Developing an H.I.V. vaccine has been a perplexing challenge that has mostly resulted in failure, but now scientists have identified key factors that allow some people to naturally suppress the H.I.V. virus—work that could lead to better vaccines to both treat and prevent the infection. Researchers believe they have identified crucial points on the virus’s surface where the immune system can successfully attack H.I.V.
People at high risk of contracting HIV can significantly lower their chances of getting the virus with a daily pill known as PrEP, or pre-exposure prophylaxis, medicine. While this innovation has led to lower rates of new HIV cases among some, others can’t stick to the once-a-day regimen, prompting scientists to search for a low-effort, long-term way for people to take PrEP on schedule.
Despite the best efforts to date, a vaccine for HIV remains beyond our reach. It seems every time researchers get close, the virus mutates to stay a step ahead, creating a biological arms race. But a team of scientists at the University of Texas believe they may have found a way to hobble HIV and drastically reduce its virulence. They want to infect susceptible cells with a “good” virus first, one that will effectively immunize them against HIV.
Researchers from Temple University have used the CRISPR/Cas9 gene editing tool to clear out the entire HIV-1 genome from a patient’s infected immune cells. It’s a remarkable achievement that could have profound implications for the treatment of AIDS and other retroviruses.
A man was recently diagnosed with HIV after 24 months on a drug intended to prevent HIV infection. A physician at the Maple Leaf Medical Clinic in Toronto, Canada who treated the patient presented the case study last week at the Conference on Retroviruses and Opportunistic Infections in Boston. Here’s what happened, and why it matters.
Nigerian Professor Produces Antivirt, An Anti Viral Drug For Treating HIV AIDS. Despite doubts in some quarters about the authenticity of his claims, Professor Maduike Ezeibe of Michael Okpara University of Agriculture Umudike (MOUAU), Abia State, has insisted that his recent therapy for the dreaded HIV and AIDS is real and effective.
