Swine flu jab narcolepsy risk is very small
Conclusion
This study confirms that the Pandemrix vaccine against swine flu is associated with a very small risk of narcolepsy in children and young people.
As the authors point out, this risk may have been overestimated if children with narcolepsy who had been vaccinated were more rapidly referred than others because of increased awareness of the link.
The methods used were practical for a rapid assessment of risk, but as this was essentially a case series analysis they are limited by a number of factors:
The rates calculated are dependent on the accurate diagnosis and identification of the cases of narcolepsy. By usin...

Experts with links to drugs industry 'hyped swine flu'
Conclusion
This was a well-conducted study, albeit based on a small sample of articles. The finding that academics with ties to the drugs industry were more likely to make a higher assessment of risk from swine flu, and those promoting the use of antiviral drugs were more likely to have industry links, is worrying.
The general issue of academics with undisclosed links to the pharmaceutical industry being interviewed by journalists is of concern. That said, the study does not prove that media coverage either fuelled public anxiety about swine flu or the policy decisions made about drug or vaccine funding.
Similarly, the...

Swine Flu, Bird Flu And Pandemic Vaccination
As the world prepares for what may be the next pandemic strain of influenza virus, in the H7N9 bird flu, a new UC Irvine study reveals that the 2009 H1N1 swine flu pandemic was deadliest for people under the age of 65, while those 65 and over had greater immunity due to previous exposure to similar viruses. Deaths from flu pandemics tend to skew younger than those from seasonal flu because of "antigenic recycling," or the fact that some parts of flu viruses have already made the rounds...

Four out of ten Brits may naturally show fewer flu symptoms
ConclusionA study of 1,414 unvaccinated people showed those with T cells targeting virus nucleoprotein still got infected by flu, but had fewer symptoms. The logic is that people with fewer symptoms are less likely to spread the virus through coughs and sneezes, which may slow the spread of both seasonal and pandemic flu strains.This is plausible, but was not directly tested in this study, so we don't know if it's true in real life. The research team suggested vaccines that boost T cell numbers might be worth exploring, as an alternative to those that try to stop virus infection altogether. An added potential benefit of th...

Could brain protein help people 'sleep off' the flu?
Conclusion
This complex study suggests the AcPb protein is playing a role in regulating normal sleep and the response to flu infection in mice.
At this stage, the implications of this research for humans are unclear, as differences between the species may mean the results would not be exactly the same in humans.
While The Telegraph suggests this "could finally lead to an effective treatment for the [flu], which until now has eluded experts", we are a long way off knowing whether this is the case.
What the researchers have shown – in mice – is if you remove this protein, mice don't fight the virus as we...

Flu Activity Now Widespread In Mass.; H1N1 Dominant Strain
BOSTON (CBS/AP) –Flu season appears to be in full swing in Massachusetts, with health officials reporting cases statewide.
Health care providers are seeing an uptick in the H1N1 strain that was prevalent in 2009. H1N1 or “Swine Flu” typically causes more illness in children and young adults, compared to older adults, although severe illness is possible in all age groups.
The Center for Disease Control says hardest hit areas include Massachusetts, New York and Pennsylvania.
Flu is usually the worst in January or February, although last year the illness hit the U.S. very hard in early December.
According to...

Anti-swine flu vaccination linked to increased risk of narcolepsy in young adults
(Wiley) Pandemrix is an influenza vaccination, created in 2009 to combat H1N1, known as Swine Flu. Now, a team of Swedish clinicians testing the vaccine for links to immune-related or neurological diseases have linked Pandemrix to an increased risk of narcolepsy in young adults.

Scientists concerned at H7N9 bird flu outbreak that has killed 24 people
• Virus killing a fifth of those infected in China• World Health Organisation considers it a serious threatScientists are seriously concerned about a new bird flu virus that is causing severe disease in China, killing a fifth of all those it infects.So far, the virus, known as H7N9, is being transmitted only to humans from chickens, but there are worries that it could mutate into a form that could be passed from one person to another. Five mutations are known to be necessary for that to happen – H7N9 already has two of them. If that occurred, it could spread worldwide with lethal effect.According to the World Health ...

Learning to Trust Flu Shots: Quasi‐Experimental Evidence from the 2009 Swine Flu Pandemic
Abstract
This paper studies consumer learning in influenza vaccination decisions. We examine consumer learning in influenza vaccine demand within a reduced form instrumental variable framework that exploits differences in risk characteristics of different influenza viruses as a natural experiment to distinguish the effects of learning based on previous influenza vaccination experiences from unobserved heterogeneity. The emergence of a new virus strain (influenza A H1N1/09) during the 2009 ‘Swine flu’ pandemic resulted in two different vaccines being recommended for distinct population subgroups with some people, who we...

Probiotic pickled turnip touted as ‘flu wonder cure’
Conclusion
This simple experiment showed that giving a bacterial extract found in Japanese pickled turnip to mice, as a preventative treatment for flu, reduced some of the symptomatic effects of flu upon subsequent infection. Specifically, it lessened body weight loss and reduced declines in general health during a seven-day flu period.
While the results are encouraging, it is too soon to roll out the red carpet and welcome a “new wonder cure” as both the headlines in the Daily Express and Mail Online suggest.
For instance, mice given the Japanese pickle extract still experienced declines in body weight of approximate...

Researchers 'a step closer' to universal flu vaccine
Conclusion
These studies have developed two different flu vaccines that could potentially offer broader protection against a variety of flu strains than current vaccines.
As yet, this research has only been conducted in animals, with one study showing an effect against different flu strains in mice and monkeys, and the other showing an effect in mice and ferrets.
As monkeys are more similar to humans than mice or ferrets, the results from these experiments are likely to be the most representative of what would happen in humans.
While the results are encouraging, it is likely that additional lab and animal research on bo...

Solving the Mystery Flu That Killed 50 Million People
MoreCalifornia Bill Banning ‘Affluenza’ Defense Is Nixed7 Ebola Patients in Guinea Fight Off the Disease4 Diseases Making a Comeback Thanks to Anti-VaxxersYears ago the environmental historian Alfred Crosby was at Washington State University, where he was teaching at the time, when on a whim he decided to pick up an old almanac from 1917. (This is apparently the kind of thing historians like to do in their spare time.) He looked up the U.S. life expectancy in that year—it was about 51 years. He turned to the 1919 almanac, and found about the same figure. Then Crosby picked up the almanac from 1918. The U.S. l...

New deadly strain of bird flu may have emerged
“Experts are concerned about the spread of a new strain of bird flu that has already killed one woman in China,” BBC News reports.
The new strain, which has evolved from an existing bird flu virus called H10N8, has infected two people in China.
A case report in The Lancet medical journal warns that potential for a new pandemic “should not be underestimated”.
Their genetic tests of the strain suggests it has adapted to infect humans more easily.
That said, experts suggest there is currently no cause for alarm. There is no evidence that the new strain can pass between humans. Also, the woman who died of the ne...
