A new type of influenza vaccine has been developed which suggests that a "universal" protection against the killer virus could be possible, according to new research.

The vaccine targets part of the virus common to all strains, meaning it could provide a way around the problem of the bug frequently mutating and making preventative treatment ineffective.

It was created by a team working for US healthcare company Sanofi using techniques that have also raised hopes of a new generation of vaccines against other diseases.

In the paper, published in the journal Nature, team leader Gary Nabel said: "This structure-based, self-assembling synthetic nanoparticle vaccine improves the potency and breadth of influenza virus immunity, and it provides a foundation for building broader vaccine protection against emerging influenza viruses and other pathogens."

Influenza kills between 250,000 and 500,000 people globally per year, according to the World Health Organisation.

Earlier this month experts warned that a deadly bird flu virus sweeping through China had taken the first steps towards becoming a global threat to human populations. In the space of one month, the avian strain known as H7N9 spread through all 31 Chinese provinces and claimed 125 victims, killing a fifth of those infected.

Scientists say it is mutating rapidly and already has two of five genetic changes believed to be necessary for human-to-human transmission. Currently the virus has made its home in chickens, and only affected people who have had close contact with the birds, often at live markets.

The Sanofi team's vaccine is built using protein "self-assembling nanoparticles", which when injected create antibodies that attach themselves to parts of the virus that are common to different strains.

In lab tests on ferrets, which can suffer the same strains of flu as humans, it was more potent and affected more strains than the current licensed vaccine, the team said. It is also safer to make than standard vaccines, which are produced by growing the virus in a lab. The DIY way it is made means similar methods could be used to create vaccines against other diseases.

Scientists gave a cautious welcome to the research, but said trials on humans were needed to see if it worked as well as hoped.

Big names in medicine are set to give an upbeat assessment of the war on AIDS on Tuesday, 30 years after French researchers identified the virus that causes the disease.

Scientists will pay tribute to the astonishing success of AIDS drugs and highlight steps being taken towards a cure -- a goal once deemed all but out of reach.

Entitled "Imagine the Future," the three-day conference builds on the 30th anniversary on Monday of the isolation of the human immunodeficiency virus (HIV).

The Nobel-winning achievement, by a team led by Luc Montagnier of France's Pasteur Institute, unmasked a killer.

"The discovery of HIV in 1983 and the proof that it was the cause of AIDS in 1984 were the first major scientific breakthroughs that provided a specific target for blood-screening tests and opened the doorway to the development of antiretroviral medications," said Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases (NIAID).

Introduced in 1996, after many years of frantic drug research, antiretrovirals are saving the lives of millions of people infected with HIV and helping to contain the virus' spread, Fauci said in an email.

By suppressing viral levels, antiretrovirals can prevent HIV being transmitted by pregnant women to their unborn children, and by infected people to their sexual partners.

But there have also been setbacks, particularly in the quest for a vaccine.

Only last month, US authorities halted the latest clinical trial -- launched in 2009 -- after the prototype formula failed to prevent infection.

Preparation to lead no worries about tick-borne disease . MAY 22, 2013 04:07. . Fear is growing after the first tick-borne virus infection case was found in Korea. The health authorities said they separated the severe fever with thrombocytopenia syndrome (SFTS) virus transmitted by a tick bite from a 60-something woman who died in August last year.

The term killer tick is exaggerated, however. When the virus was first found in China, it was known to have a 30 percent of death rate. It turned out, however, that the death rate is six percent, much lower than 20 to 30 percent of Japanese encephalitis, as only 0.5 percent of ticks are infected with the SFTS virus. This means that if a tick bites people, they do not get infected immediately, and even if people are infected, they do not die right away. Most of those who died of ticks in China and Japan as well as Korea are the elderly in the 60s and older who have weak immune system.

The wrong information that a tick bite leads to death is spreading over the Internet, however. Jeju Island is losing tourists after suspected patients are found, and tee time reservations are cancelled at golf courses there. People should be careful about ticks but there is no need to be that fearful.

According to the Korea Centers for Disease Control and Prevention, the virus caused by ticks is not new and has been in Korea for three decades. It was the first time that the authorities separated the virus from the victim, but it is highly likely that there have been people who were infected with the virus or died of it. Even if its infection rate or death rate may not be high, people need to be careful about it because there is no vaccine or anti-virus medicine.

Since the virus is transmitted by ticks, it is advised to wear long sleeves and long pants for outdoor activities so as to minimize skin exposure and after returning home, it must be effective to take a shower and wash clothes thoroughly.

Like the Severe Acute Respiratory Syndrome (SARS) and the avian flu, excessive fear makes the situation serious rather than viruses themselves. As fear dampens industries and the economy, the Health Ministry correspondents decided to refrain from using exaggerated expressions based on the reporting guidelines on infectious diseases that they made. Hopefully, Internet media outlets also should be careful about reporting not to stoke unnecessary fear.
