Cows used to produce milk that protects against HIV

Despite the misgivings that many people have surrounding cow’s milk, it is a good source of nutrients such as calcium and vitamin D. Now, thanks to scientists at Melbourne University, special milk may also be used to protect people from HIV. Working with the Australian biotechnology company Immuron Ltd, a team led by Dr. Marit Kramski has vaccinated pregnant cows with an HIV protein – the first milk that those animals produced after giving birth contained HIV-disabling antibodies.Read More

Ultrasound improves efficiency of transdermal drug delivery

Although some medications just don’t work when taken orally, the fact is that nobody likes getting injections. Research being conducted at MIT, however, could lead to a new painless method of drug delivery via the skin. Harsh though it might sound, it involves using ultrasound to blast off the outer layer of skin, so that drugs can then get into the bloodstream.Read More

Laser-based system promises to take the "ouch" out of injections

Nobody likes getting their shots, but whether childhood immunization, annual flu vaccination, or whatever else, we're required to undergo the uncomfortable sensation of needle piercing skin multiple times throughout our lives. However, a new laser-based system promises to take the “ouch” out of injections by delivering shots as painlessly as being struck by a puff of air. Read More

Immune system discovery could lead to a vaccine for heart disease

Most people probably know that plaque buildup in the arteries surrounding the heart is one of the major causes of heart disease. The reason that the plaque does accumulate, however, is often due to an inflammation of the artery walls. Recently, scientists from California’s La Jolla Institute for Allergy & Immunology were able to identify the type of immune cells responsible for that inflammation. With this knowledge in hand, they now hope to be able to develop a vaccine for heart disease.Read More

New vaccine could provide lifetime immunity to nicotine addiction

Researchers at Weill Cornell Medical College have developed a vaccine that could help existing smokers quit for good and prevent those yet to try cigarettes from ever becoming addicted. The vaccine turns the recipient’s kidney into a factory continuously churning out antibodies that clear the bloodstream of nicotine before it has a chance to reach the brain and deliver it’s addictive rush. Unlike previously tested nicotine vaccines that only last a few weeks, the effects of a single dose of this new vaccine should last a lifetime.Read More

New vaccine is effective against all major strains of hepatitis C

Although the existence of hepatitis C had been postulated in the 1970s, it wasn’t until 1989 that a team led by Michael Houghton identified the virus. Often being asymptomatic, it is estimated between 130 – 170 million people worldwide are infected with the virus that can lead to scarring of the liver and cirrhosis. Although treatment with medication is available, it isn’t effective in all cases and between 20 to 30 percent of those infected with hepatitis C develop some form of liver disease. Now Houghton and a team at the University of Alberta have developed a vaccine from a single strain that is effective against all known strains of the disease.Read More

Self-destructing syringe is made to save lives

In these days of reducing, reusing and recycling, it may seem strange that anyone would be going out of their way to make a potentially reusable product disposable. It all makes sense, however, when that product is a syringe. According to the World Health Organization, every year approximately 1.3 million people die worldwide, due to diseases contracted through the reuse of syringes. Part of this can be chalked up to needle-sharing by users of illicit intravenous drugs, but much of it is due to health care workers (particularly those with little training or in impoverished conditions) using the same syringe to inoculate multiple patients. If a syringe simply ceases to function after one use, however, reusing it is impossible. That’s the idea behind Star Syringes’ K1 Auto Disposable syringe.Read More

Spanish scientists trial promising HIV vaccine

Researchers at the Spanish Superior Scientific Research Council (CSIC) have successfully completed Phase I human clinical trials of a HIV vaccine that came out with top marks after 90% of volunteers developed an immunological response against the virus. The MVA-B vaccine draws on the natural capabilities of the human immune system and “has proven to be as powerful as any other vaccine currently being studied, or even more", says Mariano Esteban, head researcher from CSIC's National Biotech Centre.Read More

Researchers create vaccine against heroin high

Researchers at the Scripps Research Institute have created a vaccine that stops the high one gets from from heroin. Designed as a therapeutic option for those trying to break their addiction, the vaccine produces antibodies that stop heroin as well as other psychoactive compounds metabolized from heroin from reaching the brain to produce euphoric effects.Read More

Swine flu breath test could help identify infected patients

A simple swine flu breath test is currently being developed with the aim of preventing H1N1 vaccination shortages by identifying those already infected with the strain. A recent study in Glasgow, Scotland discovered that over 50 percent of the local residents vaccinated during the 2009 swine flu pandemic had already been infected with the virus. This ultimately means that they were vaccinated unnecessarily and although this would not have caused any added harm, it did expose health practitioners to the infectious virus whilst also wasting already limited supplies of the vaccine.Read More
