GlaxoSmithKline Pulls Swine Flu Vaccines in Canada.
LONDON (AP) — 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.
White said U.K.-based GlaxoSmithKline wrote to Canadian health care professionals advising them to stop using the batch on Nov. 18. She says a total of 7.5 million doses of the vaccine have been distributed in Canada.
GlaxoSmithKline is the world’s second largest drug maker by revenue. Its shares were down 0.08 percent on the London stock exchange at 1,276.50p ($21.16)

Tamiflu-resistant swine flu cluster reported in NC
ATLANTA (AP) – Four North Carolina patients at a single hospital tested positive for a type of swine flu that is resistant to Tamiflu, health officials said Friday.
The cases reported at Duke University Medical Center over six weeks make up the biggest cluster seen so far in the U.S.
Tamiflu – made by Switzerland’s Roche Group – is one of two flu medicines that help against swine flu, and health officials have been closely watching for signs that the virus is mutating, making the drugs ineffective.
About 52 resistant cases have been reported in the world since April, including 15 in the U.S. Almost all in the U.S. were isolated, said officials with the U.S. Centers for Disease Control and Prevention.
The BBC reported another cluster of five Tamiflu-resistant cases this week in Wales, in the United Kingdom.
The CDC has sent three disease investigators to North Carolina to help in the investigation there, said Dave Daigle, a CDC spokesman. CDC testing confirmed the Tamiflu-resistant cases.
All four cases at the hospital were very ill patients in an isolated cancer unit on the hospital’s ninth floor, and it is believed they all caught the flu while at the hospital, said Dr. Daniel Sexton, professor of medicine and director of the Duke Infection Control Outreach Network.
Three of the four patients died, and one is recovering, he said. Flu seems to have been a factor in each death, but they were very sick so it was hard to say that it was the primary cause, he added.
The first patient had been given Tamiflu before becoming ill with the virus, as a preventive measure. The three others were given Tamiflu after developing flu symptoms, he said.
The case is under investigation, but hospital officials said they have no evidence the cases represent a hospital-wide concern.
The North Carolina cluster is unusual, but “at this time we don’t have any information that should raise concerns for the general population,” said Dr. Alicia Frye, epidemiologist in the CDC’s flu division, in a prepared statement.
The first reported instance of Tamiflu-resistant swine flu spreading from one person to another occurred about four months ago at a summer camp in western North Carolina, where two teenage girls – cabin mates – were diagnosed with the same drug-resistant strain. Health officials said at the time that the virus may have spread from one girl to the other, or it’s possible that the girls got it from another camper.
Overall, CDC officials said Friday that swine flu cases appear to be declining throughout most of the U.S., with reports of swine flu illnesses widespread in 43 states last week, down from 46 the week before.
CDC officials also said reports have been increasing in a few states, including Maine and Hawaii. They said it’s hard to know whether the epidemic has peaked or not, and many people will be gathering – and spreading germs – next week at Thanksgiving.
