Recently, the Canadian government had to recall nearly 800,000 doses of Arepanrix, because the vaccine lots were corrupted. Now, MedImmune is recalling 4.6 million doses of the intranasal swine flu vaccine, because it is allegedly losing its potency. If you recall, this MedImmune vaccine contains LIVE H1N1 virus in the spray, so perhaps these live viruses are dying over time!

Maryland-based MedImmune is recalling nearly 5 million doses of H1N1 flu vaccine because the nasal spray appears to lose strength over time, federal health officials announced Tuesday.
The vaccine recall is the second this month caused by declining potency and comes as public health officials urge millions of Americans to get vaccinated against H1N1.
The action affects more than 4.6 million doses, but the vast majority have already been used, according to the Food and Drug Administration. Agency officials said the vaccine was strong enough when it was distributed in October and November.
