Not exact matches

Future HIV vaccine research should consider the balance between responses that favor protection and those that lead to susceptibility to infection.

These findings provide insights for the design of vaccines that can «kick - start» and then shape the maturation of broadly neutralizing antibodies in HIV uninfected individuals, to provide protection from HIV exposure.

Vaccine Protection of Chimpanzees Against Challenge with HIV -1-Infected Peripheral Blood Mononuclear Cells

Vaccine - mediated protection of nonhuman primates against low doses of cell - free HIV - 1, HIV - 2, or simian immunodeficiency virus (SIV) has been demonstrated.

Thus, in principle, a successful vaccine has to stimulate the first B cells in this lineage and then coax them along a fairly narrow evolutionary path until they have changed enough to provide effective protection against HIV.

Recent research has yielded new information about immune responses associated with — and potentially responsible for — protection from HIV infection, providing leads for new strategies to develop an HIV vaccine.

In the 30 years since scientists identified HIV as the cause of AIDS, the virus has proved unbeatable — hiding in the very immune cells that would kill it; reflexively and rapidly mutating; mysteriously persisting in the gut, kidneys, liver, and brain; subverting every vaccine (the best one so far has given only 30 percent protection); and roaring back to life almost the moment drugs are stopped.

That's the question posed by researchers in the journal BMC Immunology, who think that the vaccine might have offered partial protection against HIV.

In a previously published paper, Barouch and colleagues, including Colonel Nelson L. Michael, MD, PhD, director of the Military HIV Research Program at the Walter Reed Army Institute of Research (WRAIR) and Stephen Thomas, MD, Upstate Medical University, State University of New York, demonstrated that three different vaccine candidates provided robust protection against Zika virus in both mice and rhesus monkeys.

A new study led by scientists at Beth Israel Deaconess Medical Center (BIDMC) shows that an HIV - 1 vaccine regimen, involving a viral vector boosted with a purified envelope protein, provided complete protection in half of the vaccinated non-human primates (NHPs) against a series of six repeated challenges with simian immunodeficiency virus (SIV), a virus similar to HIV that infects NHPs.

«We previously showed that adenovirus vector - based HIV - 1 vaccine candidates offered partial protection against SIV when given alone,» said lead author Dan H. Barouch, M.D., Ph.D., director of the Center for Virology and Vaccine Research at BIDMC and professor of medicine at Harvard Medical vaccine candidates offered partial protection against SIV when given alone,» said lead author Dan H. Barouch, M.D., Ph.D., director of the Center for Virology and Vaccine Research at BIDMC and professor of medicine at Harvard Medical Vaccine Research at BIDMC and professor of medicine at Harvard Medical School.

Although an autologous tier 2 NAb response is not sufficient for vaccine protection against HIV - 1, it may be a necessary step in various strategies intended to induce bNAbs.

«Novel HIV vaccine regimen provides robust protection in non-human primates.»

«A vaccine that can provide gloabal protection from HIV, along with other proven prevention techniques, is our best hope to control the HIV pandemic.

So far, in the 30 years since the AIDS virus was identified, only one vaccine candidate has shown any protection at all, reducing the risk of contracting HIV by 31 percent.

This approach will also elucidate mechanisms of anti-body mediated protection from infection by HIV - that are highly likely to inform vaccine design.

This premature enthusiasm has more recently given way to caution as the technology has gradually been transferred to humans, with only limited short - term success.3 Finally, since HIV usually enters the body through mucosal surfaces — the vagina and rectum — augmenting an immune response at these portals of entry by using what scientists call mucosal AIDS vaccines might be an additional way to improve protection against infection.

Several other planned vaccine trials and research studies that will begin in the coming years will continue to work towards a vaccine that delivers potent protection against HIV.

The U.S. Military HIV Research Program is part of a public - private partnershipworking to improve the original RV144 vaccine and achieve higher levels of protection.

The holy grail of AIDS prevention is a single - dose, safe, affordable, oral vaccine that gives lifelong protection against all subtypes of HIV.

These problems become easier to understand when one considers how a vaccine to prevent HIV infection would have to work if it was to produce what experts call sterilizing immunity — that is, complete protection from infection.
