The first human trials of a vaccine for H1N1 swine flu have begun in the Australian city of Adelaide.There is added urgency in the battle to beat the virus after the World Health Organisation revealed it is the fastest-moving pandemic in history. While the experts are confident their product can protect, injecting the right amount is crucial. Andrew Cuthbertson of Commonwealth Serum Laboratories said: “Because this is a novel strain of influenza and sometimes we can get results which are a little different from the normal seasonal vaccine, we are going to be running a trial to confirm the dose.” At 700. the number of global swine flu deaths has risen significantly since earlier this month according to the WHO’s figures, heightening concerns. In Europe, there is soul-searching over whether schools should remain shut after the summer holidays to stem the virus’s spread. At the peak of the epidemic in the United States, more than 700 schools closed. Airports and airlines are also in the frontline. Increasingly, passengers are under scrutiny for symptoms, with, in some cases, the risk of being banned from boarding a flight in case they infect others.
