Scientists Work on a Vaccine to Prevent Strokes

Researchers at Sweden’s Karolinska Institutet have been conducting studies on for many years. Among their findings are studies indicating that stroke victims lack a certain antibodies, anti-PC, in their immune systems that normally reduces the risk of arteriosclerosis, a thickening of arterial walls that can lead to stroke.  Their most recent study provides the impetus to move ahead with the development of a preventative vaccine.

Free Trip To Mexico… In Return Volunteers Test Experimental Drug


Volunteers are being offered a free trip in return for taking part in a drugs trial

It must be the only travel agent that actually hopes its holidaymakers will eat something dodgy.  A drugs firm is offering free trips to Mexico for nearly 1,000 volunteers – on condition that they try out a new remedy for upset stomachs, and come in for tests if they do fall ill.

Implantable Cancer Vaccine First To Eliminate Tumors In Mice


A polymer implant, 8.5 mm in diameter, is embedded with chemical signals that encourage immune cells to attack tumors.

A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine.

Anti-Smoking Vaccine May Be Available Soon


The vaccine is injected and works by creating anti-bodies

Smokers could soon have access to an injectable vaccine to help them break the habit following a deal between GlaxoSmithKline and Nabi Pharmaceuticals, the company that developed the drug.  The NicVAX vaccine works by preventing nicotine in tobacco entering the brain, where it creates an addictive sensation of pleasure.  Trials have shown it can halve the number of people who return to smoking after trying to give up.

Less Education Means More H1N1 Concern In The U.S.


Low-income Americans with no more than a high school education appear more likely to get vaccinated against H1N1 swine flu than people with more money and better schooling, according to a poll released on Friday.   A telephone survey of 3,003 U.S. adults conducted by Thomson Reuters found that 49.8 percent of people with lower education levels were very concerned about H1N1, compared with only 29 percent of those with at least a four-year college degree.

Flu Vaccines Hit A Wall – Scientists Struggle To Speed Vaccine Development


Making a vaccine against seasonal influenza is a constant catch-up game. Scientists must predict which of the constantly mutating virus strains will be most virulent six months in the future, the amount of time it takes to manufacture the vaccine. The system has worked well enough for the regular flu. But when new, virulent strains emerge–including the current, rapidly spreading swine flu (H1N1)–the traditional approach falls short. Even as consumers clamored for a vaccine, it took seven months and around 48,000 confirmed U.S. cases before the first H1N1 vaccines were shipped to hospitals around the country.

Medical Breakthrough: Experimental Vaccine That Prevents Infection With AIDS Virus


For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.  The World Health Organization and the U.N. agency UNAIDS said the results “instilled new hope” in the field of HIV vaccine research.

1 In 3 Teenage Girls Gets Cervical Cancer Vaccine


One in three teenage girls have rolled up their sleeves for a vaccine against cervical cancer, but vaccination rates vary dramatically between states, according to a federal report released Thursday. The highest rates were in Rhode Island, New Hampshire and Massachusetts, where more than half of girls ages 13 through 17 got at least one dose of the three-shot vaccination. The lowest rates were in Mississippi, Georgia and South Carolina, where fewer than 20% got at least one shot.

Potential Way To Make AIDS Vaccine Found


The first new HIV antibodies to have been identified in more than 10 years, PG9 and PG16

The discovery of immune system particles that attack the AIDS virus may finally open a way to make a vaccine that could protect people against the deadly and incurable infection, U.S. researchers said on Thursday.

Colon Cancer Vaccine

A cancer vaccine with a twist is making headway in clinical trials at the University of Pittsburgh School of Medicine. Rather than targeting a cancer-related virus–the way Gardasil targets human papillomavirus to prevent some cervical cancers–the new vaccine triggers the immune system to attack a faulty protein that’s often abundant in colorectal cancer tissue and precancerous tissue.

Scientists Warn Virus Could Cause Heart Disease In Adults

Scientists Warn Virus Could Cause Heart Disease In Adults

The risk of heart attack is increased by the virus, spread through bodily fluids 

New research suggests that a common infection affecting 60 to 99 per cent of adults could result in high blood pressure and hardening of the arteries – leading causes of heart disease, stroke and kidney disease.
