Researchers have gained important clues about immune system responses that could play a role in protecting people from HIV infection in follow-up studies from the world's largest HIV vaccine trial to date.

Younger girls are more likely than adult women to report side effects after receiving Gardasil, the human papillomavirus vaccine. The side effects are non-serious and similar to those associated with other vaccines, according to a new study.

The vaccination against human papillomavirus (HPV) reduces the risk of a renewed HPV-associated illness in patients who have already had diseases as a consequence of an HPV infection new research suggests. It had previously been the view that the HPV vaccination had a purely preventative effect and was also only effective in young women and men.

New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed to inhibit it. This finding, from studies in human cell cultures, may represent a broader targeting strategy used by other viruses, and may lay the scientific groundwork for developing more effective treatments for infectious diseases.

Marijuana-like chemicals trigger receptors on human immune cells that can directly inhibit a type of human immunodeficiency virus (HIV) found in late-stage AIDS, research suggests.

A coalition of three health groups has released new guidelines for the prevention and early detection of cervical cancer. The guidelines generally advise a reduction in the number of tests women get over their lifetime to better ensure that they receive the benefits of testing while minimizing the harms.

Researchers have successfully flushed latent HIV infection from hiding, with a drug used to treat certain types of lymphoma.

Using human immune system cells in the lab, AIDS experts have figured out a way to kill off latent forms of HIV that hide in infected T cells long after antiretroviral therapy has successfully stalled viral replication to undetectable levels in blood tests.

Scientists have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were 'so to say' vaccinated with their own cells. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists have reported.

One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now a researcher has discovered a compound that could help put the immune system back in the hunt.
