An unlikely hero has emerged in the quest to fight HIV: the cow. In a first for any animal, including humans, four cows injected with a type of HIV protein rapidly produced powerful antibodies against the virus, researchers report. Learning how to induce similar antibodies in humans may be key to a successful HIV vaccine.

Six members of the Presidential Advisory Council on HIV/AIDS have angrily resigned, saying that President Trump doesn’t care about HIV.

Donald Trump would like for the United States to spend $1.1 billion less on HIV-treatment programs in sub-Saharan Africa, and $524 million less on contraception for the global poor. On the plus side, these cuts will make it easier to finance the president’s border wall, which he hopes to spend $1.6 billion on in 2018.

Young people on the latest HIV drugs now have near-normal life expectancy because of improvements in treatments, a study in The Lancet suggests. Twenty-year-olds who started antiretroviral therapy in 2010 are projected to live 10 years longer than those first using it in 1996, it found. Doctors say that starting treatment early is crucial to achieve a long and healthy life.

New research reveals that HIV DNA can be excised from the genomes of living animals to eliminate further infection.

A few days before Christmas 2016, a phone call took place that no one could have predicted. One of the world’s most esteemed HIV doctors, Professor Sheena McCormack – whose life’s work as an epidemiologist has been to track and fight the virus – picked up the phone to deliver a message that would make headline news: In the space of 12 months, the number of gay men in London being diagnosed with HIV had dropped by 40%. Across England it was down by a third.

A new vaccine-based treatment for HIV has succeeded in suppressing the virus in five patients, raising hopes further research could help prevent Aids without the need for daily drugs. Researchers combined two innovative HIV vaccines with a drug usually used to treat cancer in the trial, conducted over three years at the IrsiCaixa Aids Research Institute in Barcelona. After receiving the treatment, the virus was undetectable in five out of 24 participants and its spread was stopped by their immune systems...

As people with HIV age, they find themselves subject to the same issues that face healthier senior citizens. Earlier this year, researchers at Georgetown University announced that a 71-year-old man was the first HIV patient to be diagnosed with Alzheimer’s disease.

The VMMC Experience Project recently sent cameras into Uganda and Kenya to document the realities of the mass circumcision program. Since 2008, western public health giants* have been circumcising Africans by the millions to slow the spread of HIV/AIDS. American taxpayers are funding the effort through the President’s Emergency Plan for AIDS Relief (PEPFAR). An estimated 12 million men and boys have been circumcised to date. The world has not heard a word from them until now.

They had the remarkable luck to survive AIDS, and the brutal misfortune to live on. By Erin Allday.

Scientists say a new vaccine against HIV, to be tested in a trial to be launched in South Africa this week, could be "the final nail in the coffin" for the disease if it is successful.

Scientists have discovered an antibody produced by an HIV-positive patient that neutralises 98 percent of all HIV strains tested - including most of the strains that are resistant to other antibodies of the same class. Due to HIV’s ability to rapidly respond to the body’s immune defences, an antibody that can block a wide range of strains has been very hard to come by. But now that we’ve found one, it could form the basis of a new vaccine against the virus.

A man with HIV who says he had ritual sex with 104 women and girls faces up to five years in jail, if convicted. But some ask why the children's parents are not in the dock too.

Researchers at Imperial College London and the privately-held U.S. firm DNA Electronics developed a type of HIV test using a USB Stick that will give a fast and highly accurate reading of how much virus is in a patient’s blood. The device needs a drop of blood to be placed onto a spot on the USB stick to detect HIV and then creates an electrical signal that can read by a computer, laptop or handheld device. The USB stick is not only very accurate, but it can offer results on HIV levels in less than 30 minutes.

In South Africa, a rare group of children unknowingly find themselves resistant to the effects of HIV. Even without antiretroviral treatment, they will never develop AIDS, or so scientists believe. Unlike adults and other children who succumb to the virus if not treated -- enabling it to attack their immune cells and weakening their immunity to disease -- these kids harbor huge amounts of HIV within their blood but remain unscathed. In fact, they're healthy.

UK scientists and clinicians working on a groundbreaking trial to test a possible cure for HIV infection say they have made remarkable progress after a test patient showed no sign of the virus following treatment. The research, being carried out by five of Britain’s top universities with NHS support, is combining standard antiretroviral drugs with a drug that reactivates dormant HIV and a vaccine that induces the immune system to destroy the infected cells.

A British man could become the first person in the world to be cured of HIV using a new therapy designed by a team of scientists from five UK universities. The 44-year-old is one of 50 people currently trialling a treatment which targets the disease even in its dormant state. Scientists told The Sunday Times that presently the virus is completely undetectable in the man’s blood and if it remains that way it will be the first complete cure.

Scientists have discovered a highly aggressive new strain of HIV in Cuba that develops into AIDS three times faster than more common strains of the virus. This finding could have serious public health implications for efforts to contain and reduce incidences of the virus worldwide. Researchers at the University of Leuven in Belgium say the HIV strain CRF19 can progress to AIDS within two to three years of exposure to virus. Typically, HIV takes approximately 10 years to develop into AIDS. Patients with CRF19 may start getting sick before they even know they've been infected...

According to the CDC, in some instances the rates of STD infection for people over 65 rivals that of people in their 20s.

Those fighting epidemic say 2030 target is unrealistic as efforts to defeat it falter amid rising infection levels and drug resistance. By Sarah Boseley.
