New Warning Over Bird Flu Vaccine - University Of Leicester Professor Calls For Vaccination Programme

A team of international researchers has written to the journal, The Lancet Infectious Diseases, calling for people to be vaccinated now against bird flu in order to mitigate the effects of global pandemic.


Professor Karl Nicholson, Professor of Infectious Diseases at the University of Leicester and Consultant Physician at the Leicester Royal Infirmary is among those who has written the article.



The experts say that the World Health Organisation and national governments should give "urgent consideration" to priming potential victims with a preparatory jab.



Administering an initial vaccination would help to build up the immune system followed by a booster shot as soon as the first signs of a pandemic emerge.




People primed in advance would then be fully protected in a week instead of six weeks.
Professor Nicholson and colleagues said there may be no warning before deadly H5N1 bird flu explodes in the human population.



Current vaccination strategies require two jabs spaced six weeks apart, but the researchers warn that after six weeks it may be too late to prevent widespread loss of life.



They concluded: "The maximum benefit from using a pre-pandemic vaccine may be gained from priming populations before there is evidence of a novel virus emerging and spreading, when systematic supply, distribution and vaccination strategies can be put in place."



An international study led by University of Leicester researchers recently determined that vaccination will be the best way to protect people in the event of the next influenza pandemic - but that each person would need two doses.


In an article in the New England Journal of Medicine published on October 9, researchers from the University of Leicester and University Hospitals of Leicester report on a study carried out at the Leicester Royal Infirmary.


Dr Iain Stephenson, Consultant in Infectious Diseases at the Infirmary and a Clinical Senior Lecturer at the University of Leicester carried out the research with Professor Karl Nicholson.


An influenza pandemic occurs when a new influenza strain emerges (one to which humans have no immunity), mutates and spreads globally as a virus. Although it is not possible to predict the actual pandemic influenza strain, global health authorities have identified H5N1 avian influenza as a strain with the greatest pandemic potential in humans. H5N1 is currently circulating in birds and has caused serious illness in more than 380 people worldwide with a mortality rate, among people known to have been infected, of greater than 60 percent.
