Over 100,000 doses of the H1N1 vaccine are being recalled across Canada after it was discovered in Manitoba that a higher-than-usual amount of allergic reactions have occurred from one batch. Drug manufacturer, GlaxoSmithKline has requested that over 170,000 doses coming from the so called questionable batch, not be administered.
“GSK is taking this cautionary action because the Public Health Agency of Canada has received a higher than expected number of reports of anaphylaxis in this lot number compared to other lots,” the company disclosed in a written statement on Thursday.
CTV News is also reporting that the country’s chief public health officer, Dr. David Butler-Jones, outlined that out of the 6.6 million doses of H1N1 vaccine administered so far to Canadians, there have been 36 serious adverse reactions reported.
Side effects that are not unexpected and may occur after receiving the H1N1 vaccine are nausea, soreness, headaches and fever, all of which have been reported as reactions to the seasonal flu shot.
