Retroviruses - the family of viruses that includes HIV - are almost half a billion years old, according to new research by scientists at Oxford University.
Scientists identified an antibody from an HIV-infected person that potently neutralized 98 percent of HIV isolates tested, including 16 of 20 strains resistant to other antibodies of the same class.
A new study has demonstrated that combining an experimental vaccine with an innate immune stimulant may help lead to viral remission in people living with HIV.
