LONDON — Pharmaceuticals company GlaxoSmithKline PLC said Tuesday it has advised medical staff in Canada to not use one batch of swine flu vaccines in case they trigger life-threatening allergies.
Company spokeswoman Gwenan White said that they issued the advice after reports that one batch of the swine flu vaccine might have caused more allergic reactions than normal.
“We have advised health care professionals not to use that batch while health authorities and GlaxoSmithKline investigate,” she said.
White said the batch at issue, which has been distributed across Canada, 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.
