The pharmaceutical company GlaxoSmithKline says it has advised medical staff in Canada to not use one batch of swine flu vaccine for fear it may trigger life-threatening allergies.
She says the affected batch contains 172,000 doses of the vaccine. She declined to say how many doses had been administered before the advice to stop using them was given.
