Scientists have developed a flu vaccine that works against more than one strain of the influenza virus which has raised the prospect of a “universal” vaccine against all types of flu.
Currently, seasonal flu vaccines are designed against specific viral strains thought to pose the greatest threat. This means that a vaccine is often not effective if a known viral strain starts to mutate – a constant problem with influenza viruses.
This happened last winter when health officials said that the flu vaccine they had prepared the year previously in anticipation of the influenza season protected only 3 per cent of those who were inoculated instead of a more typical 50 per cent protection rate.
Researchers have made many attempts in the past at making broader vaccines without success. Now, two groups working independently of one another have made breakthroughs by developing vaccines based on a part of the influenza virus that rarely mutates.
Both sets of researchers developed their vaccines by concentrating on the “stem” of a viral protein known as haemagglutinin (H) rather than the rapidly mutating “head” of the protein. The flu virus uses haemagglutinin to latch on to human cells, and it is the head of the protein that changes rapidly to evade the body’s immune defences.
Each research team showed that the new kind of vaccine completely protects laboratory mice against several strains of the H1 subtype of influenza virus. They also found that the vaccine – based on the H1N1 flu virus – also worked against the H5N1 subtype of avian flu.
However a study in the journal Nature Medicine, led by Gary Nabel and Barney Graham of the US National Institute of Allergy and Infectious Diseases in Bethesda, Maryland, also showed that the new vaccine protected immunised ferrets against H5N1. Ferrets are the closest animal model to human influenza because both humans and ferrets share the same receptor protein that flu uses to infect cells.

Chlamydia is extremely common. There were 208,755 new infections in England in 2013, and around the world an estimated 100 million are infected each year. In around half of men, and 70 to 80 per cent of women who get it, there will be no symptoms. However, in some it can cause pain and if left untreated can lead to infertility.

Health news: in pictures Sunshine boosts fertility by a third Exposure to sunlight can boost the likelihood of a woman having a baby much as a third, according to scientists. Couples hoping to conceive may find that heading to sunnier climes may improve their chances, according to experts. Fertilisation rates, live births, and the number of eggs all improved after women were in the sun. Scientists studied the IVF results of 6,000 women over a six-year-old period, and analysed them alongside the weather conditions in the month before women started treatment.

Health news: in pictures Cholesterol U-turn - fatty foods might not be bad for us The US government has dropped fatty foods containing cholesterol - long thought to cause heart disease and strokes - from its list of 'nutrients of concern', following the publication of a new report. For 40 years, people have been warned against eating fatty foods containing high cholesterol, such as butter, eggs, red meat, shellfish and liver, because of supposed links to the substance in our blood. But now the US Department of Agriculture plans to revoke their long-standing dietary guidelines and to focus on the amount of sugar people are eating, instead.

Health news: in pictures Knuckle-cracking mystery solved The mystery of what happens to make a knuckle crack has been solved thanks to a simple test of “pull my finger”. In a new study published by the University of Alberta, a team of researchers used MRI video to determine what happens inside a finger joint to make it “pop”. They observed that the sound is caused by a rapidly forming cavity inside the joint when pulled. “We call it the ‘pull my finger study’– and actually pulled on someone’s finger and filmed what happens in the MRI,” explained lead author Greg Kawchuk. More than just settling a scientific curiosity, the findings bring researchers closer to determining whether or not the ability to crack ones’ joints is inherent or even healthy. But they are still unclear as to why only some people can crack their joints on demand

Health news: in pictures DNA changes could explain why autism runs in families Scientists have come up with a possible explanation for why autism appears to run in families – suggesting it can be triggered by changes in the chemicals attached to DNA. A study of sperm from 44 fathers of babies who showed early signs of autistic symptoms shows that “epigenetic” changes to the men’s DNA could transmit the condition to the next generation. Epigenetic changes involve modifications in chemicals attached to the DNA molecule – rather than mutations to the DNA sequence itself. The changes detected in this study have been linked with abnormal development of nerve cells in the brain

Health news: in pictures Alzheimer's breakthrough Scientists have broken new ground in the search for an Alzheimer’s cure, discovering a new potential cause of the disease, which it may be possible to target with drug treatments. Experts said the findings, from Duke University in North Carolina, USA, could “open new doors” in the increasingly frustrated global hunt for a dementia therapy. Researchers at Duke announced that their studies of Alzheimer’s in mice had thrown up a new process they believe contributes to the disease’s development. They observed that in Alzheimer’s, immune cells that normally protect the brain instead begin to consume a vital nutrient called arginine. By blocking this process with a drug, they were able to prevent the formation of ‘plaques’ in the brain that are characteristic of Alzheimer’s disease, and also halted memory loss in the mice

Health news: in pictures 1 in 3 women will get bacterial vaginosis but are unlikely to know what it is One in three women will get bacterial vaginosis (BV), the most common cause of unusual vaginal discharge, at some time in their life. However, many women do not know what it is, and can confuse the symptoms for other conditions, such as thrush. Although the causes of BV are not very well understood, it develops when the normal environment of the vagina changes, when there are less of the normal bacteria (lactobacilli), an overgrowth of other types of bacteria, and the vagina becomes more alkaline. BV is not a sexually transmitted infection, but it can develop after sex, and any woman might get it including those in same sex relationships and those who have never had sex. Around half of women with BV will not have any signs and symptoms at all, or may not be aware of them. Where there are symptoms, these can include an increase in the usual vaginal discharge, and for it to become thin and watery, change to a white/grey colour and develop a strong, unpleasant, fishy smell, especially after sexual intercourse. Treatment is simple and involves taking antibiotic tablets, either as a single dose or for up to a week, or a cream or gel for use in the vagina for around one week

Health news: in pictures Drug made from cannabis could help fight severe epilepsy Hope has been raised for children with severe forms of epilepsy that are difficult to treat after trials of a new drug derived from cannabis showed promise in helping to reduce the number of debilitating seizures suffered as a result of the condition. The study, published by the American Academy of Neurology, tested 213 people, ranging from toddlers to adults, who had severe epilepsy that did not respond to other treatments, using a drug made from a medicinal form of Marijuana. Participants were given the drug containing canabidiol, also known as CBD, a component of cannabis that does not include the psychoactive part of the plant that creates a “high,” in the form of a liquid. Results released this week show that, of the 137 people who completed the 12-week study, there was a 54 per cent average decrease in the number of seizures the participants experienced. Twenty three people with Dravet syndrome completed the study and found the number of convulsive seizures they experienced had dropped by 53 per cent. Of the 11 participants who stayed the 12-week trial that had Lenox-Gastaut syndrome, they experienced a 55 per cent drop in the number of atonic seizures or “drop attacks”, which cause a sudden loss of muscle tone and usually happen many times a day

Health news: in pictures New breath test could be used to detect stomach cancer Cancers of the stomach could soon be detected using a simple breath test, researchers have said, potentially saving lives by picking up the condition early. A new trial of the tests, which measure the level of compounds in the breath that can point to cancer risk, have proved them to be accurate and cost-effective. Stomach cancer is a relatively rare condition, affecting around 7,300 people in the UK every year. However, the outlook for patients is often poor, because the condition is so rarely diagnosed early enough for successful treatment. Early symptoms, such as indigestion and burping, are the same as for many other minor conditions, so the cancer is often missed until it is too late. The only existing test is an endoscopy, where a tube is inserted into the stomach down the throat

Health news: in pictures 'Loneliness maps' Maps pinpointing where the country’s loneliest people might live must be used to help focus services to those who are most isolated, according to a new report. The Campaign to End Loneliness, which compiled the report with the University of Kent, warned as it released the document that loneliness and isolation are as harmful to our long-term health as smoking 15 cigarettes a day. It can also put people at risk of developing dementia, high blood pressure and depression. As many as ten per cent of the older population all or most of the time, according to the charity. And people experiencing severe loneliness may in turn put a strain on the NHS and loved ones, as they are more likely to visit their GP more often, and enter residential care earlier. To help tackle the issue, charities and local services should use existing data to compile so-called 'loneliness maps' which predict where their most lonely resident live, in order to syphon limited resources to the people most in need

It was thought that social factors that can stunt height, such as poor nutrition in childhood, might explain why petite people were more likely to develop heart problems. But a new study has found that every 2.5 inches difference in height between two people makes the shorter person 13.5 per cent more likely to develop heart disease

Health news: in pictures HIV breakthrough A new type of HIV treatment involving the transfusion of a synthetic antibody designed to prevent the virus from attacking human cells has shown startling trial results. Patients injected with the antibody saw a 300-fold reduction in their viral “load” – the amount of HIV circulating in their blood. The antibody has been specifically designed to block the key viral protein receptor needed to infect human blood cells. Previous tests on HIV antibodies had produced disappointing results. But the latest clinical trial resulted in a dramatic lowering of the virus, which was maintained for several weeks after the initial injection for some patients. The researchers believe that using synthetic antibodies designed to become attached to the surface proteins on the outer membrane of HIV could provide an alternative form of treatment to anti-retroviral drugs, and may also help to design therapeutic vaccines

“It’s really moving us in the direction of extending the breadth of protection of an influenza vaccine. We hope eventually to protect against any flu viruses that we encounter – and this is a potential step in that direction,” Dr Nabel said.
“A universal vaccine is an awfully grand ambition – that is to protect against all flu viruses to a high degree. But if we can improve current vaccines by giving them broader protection, then that would be good,” he said.
It will take between three and five years to carry out further development and testing before the vaccine could be tried on human volunteers, he added.
The team built the vaccine by isolating the stem section of the virus’s haemagglutinin protein and fusing it with nanoparticles made from the ferritin protein, which normally carries oxygen around the body. These particles stimulated the immune system to make antibodies against flu viruses.
The second study, to be published in the journal Science , was led by Antonietta Impagliazzo of the Crucell Vaccine Institute in Leiden, the Netherlands and Ian Wilson of the Scripps Research Institute in La Jolla, California.
Professor Sarah Gilbert of Oxford University said: “This is an exciting development, but the new vaccines now need to be tested in clinical trials to see how well they work in humans. This will be the next stage of research, which will take several years. So we are still some way from having better flu vaccines for humans.”
Fighting flu: New global network The World Health Organisation (WHO) has established a network of collaborating centres around the world to help combat the influenza virus.
The centres will be responsible for collecting blood samples from flu victims and looking out for new types of the virus that may risk creating a pandemic.
The first step towards the production of a pandemic vaccine starts when a centre detects an influenza virus strain that differs significantly from those in circulation. The information is then communicated to the WHO.
At the same time, the centres are involved in the constant checking of viral mutations to ensure that the vaccines being prepared for seasonal flu are correctly targeted against the genetic changes to the virus’s proteins.
These new types of flu viruses are then used to make vaccines, which are designed to stimulate the immune system to recognise and attack the haemagglutinin protein of the virus. The manufacturing process, which involves growing the flu viruses in hens’ eggs, takes several months.
