The pharmaceutical company GlaxoSmithKline says it has advised medical staff in Canada to not use one batch of H1N1 flu vaccine for fear it may trigger life-threatening allergies.
A spokesman says the affected batch contains 172-thousand doses of the vaccine.
She declined to say how many doses had been administered before the advice to stop using them was given.
