Associated PressPharmaceuticals 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.

On a related note, the NIAID/CDC seems to have plenty of thimerosal-free (and thimerosal-removed) versions of these injectable vaccines to use for all of their safety/efficacy tests. Meanwhile, almost all of us, including pregnant women and little kids, are being given the thimerosal-spiked versions.

No. The 2009 H1N1 influenza vaccine and the seasonal influenza vaccine used in these trials do not contain thimerosal or adjuvants.http://www3.niaid.nih.gov/news/QA/H1N1pregnanttrials.htmDoes the vaccine contain either the preservative thimerosal or an adjuvant?
No. The vaccine does not contain thimerosal, a preservative.http://www3.niaid.nih.gov/news/QA/H1N1VacASTHMAqa.htmDuring the production of the vaccine, thimerosal, a chemical that prevents bacterial contamination, is required. This chemical is removed in the preparation of the single-dose syringes containing the vaccine, which will be used in this clinical trial.http://www3.niaid.nih.gov/news/QA/H1N1VacHIVChildYouthPregWomenqa.htmThe 2009 H1N1 influenza vaccine manufactured by Novartis contains a trace amount of thimerosal, a mercury derivative used in the manufacture of the vaccine and removed by subsequent purification steps.
