British scientists have edged closer to developing a "holy grail" universal influenza vaccine that would tackle all strains of the illness.

Researchers at Imperial College London (ICL) have drawn on the results of a study into the 2009 swine flu pandemic, which found those with more virus-killing immune cells in their blood at the start of the pandemic avoided severe illness.

They believe a vaccine that stimulates the body to produce more of these cells - known as CD8 Ts - could be effective at preventing flu viruses, including new strains that cross into humans from birds and pigs, from causing serious disease.

Professor Ajit Lalvani from the National Heart and Lung Institute at ICL, who led the study, said: "New strains of flu are continuously emerging, some of which are deadly, and so the holy grail is to create a universal vaccine that would be effective against all strains of flu."

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

The ICL announcement comes after scientists in America said they thought they might have developed "universal" protection against the killer virus.

Speaking in May, the US researchers said the vaccine 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.

"Research has found no evidence that vitamin C prevents colds," says Dr Hasmukh Joshi, vice-chair of the Royal College of GPs. In 2007, the authors of a review of 30 trials involving 11,000 people concluded that, "regular ingestion of vitamin C has no effect on common cold incidence in the ordinary population". A daily dose of vitamin C did slightly reduce the length and severity of colds. When it comes to flu, one person in three believes that taking vitamin C can cure the flu virus. It can't. "Studies found that vitamin C offers a very, very limited benefit," says Dr Joshi. "I wouldn't recommend it." Information from NHS Choices.
