DeVries proposed the idea to Kammen in a city office, As they’d save money on their energy,K. infected chickens with Marek’s disease virus of different strains known to span the spectrum from low to high virulence When the birds weren’t vaccinated infection with highly virulent strains killed them so fast that they shed very little virus—orders of magnitude less than when they were infected with less virulent strains But in vaccinated birds the opposite was true: Those infected with the most virulent strains shed more virus than birds infected with the least virulent strain In one experiment unvaccinated birds infected with the most virulent strains were housed together with healthy birds Again the infected chickens were dead in no time leaving them no chance to spread the disease to their healthy cagemates But when vaccinated birds were infected with the highly virulent strain they lived longer and all the healthy birds housed with them became infected and died Thus "vaccination enabled the onward transmission of viruses otherwise too lethal to transmit putting unvaccinated individuals at great risk of severe disease and death” the authors write online today in PLOS Biology The study is convincing says Michael Lssig a physicist at the University of Cologne in Germany who studies the evolution of influenza "But it’s a very special set of circumstances" he cautions "I would be careful about drawing general conclusions” Adrian Hill a vaccine researcher at the University of Oxford in the United Kingdom says the experiments support the idea that vaccines helped make Marek’s disease deadlier but don’t prove it Many other things have changed in the poultry industry in the last decades; flocks have become much bigger for instance which could also favor more virulent strains But Read says those "hot strains" would die out very quickly if the vaccines were taken away Hill doesn’t doubt that some vaccines could lead to enhanced virulence; the real question is how likely this is to happen His answer: It’s highly unlikely and not something we should be worried about "They have taken 15 years to do an experiment on the only example of this happening” Read counters that there may well be other examples Feline calicivirus which causes a respiratory infection in cats is a strong candidate he says; “there have been outbreaks of “superhot” strains in vaccinated populations” Read is particularly worried about avian influenza In Europe and the United States entire poultry flocks are usually culled to stop an outbreak; Asian farmers often use bird flu vaccines "You could have the emergence of superhot strains” as a result he says Ab Osterhaus a virologist at Erasmus MC in Rotterdam the Netherlands says this is “very unlikely but a scenario that cannot be excluded” But what about human diseases Most human vaccines in use today aren’t "leaky"; they are very good at stopping disease transmission But as researchers turn to diseases that are more difficult to protect against such as malaria or HIV they are setting their sights lower aiming for vaccines that prevent severe disease but not infection "We are entering the era of leaky vaccines in humans” Read says Candidate vaccines against Ebola or malaria—one of which recently received an important stamp of approval in Europe—should definitely be used if they are safe and effective he says but they could lead to more virulent pathogens "We need to have a responsible discussion about this” But to Hill these comments themselves are irresponsible Read "has no more evidence this will happen with an Ebola vaccine than that it’ll happen with any other vaccine in humans” he says "He should stop scaremongering” The whole distinction between leaky and nonleaky vaccines is flawed Hill argues: "Every vaccine is leaky in that some people don’t get protected by it some people are partially protected some people have prevention of disease and others prevention of infection”Millions of people around the world receive a shots every month? such as bed nets for malaria.Singh said.
