Severe allergic reactions to the H1N1 vaccine have been reported.
Some Canadian provinces have stopped using a batch of the H1N1 flu vaccine after six people experienced severe allergic reactions. Health Canada and vaccine manufacturer Glaxo-Smith-Kline have asked the governments of several provinces to stop using a batch of 172,000 doses.
At least 65 million doses of H1N1 flu vaccine made by various companies have been administered so far worldwide. In Nova Scotia, the parents of a 19-month-old say after he got a second flu shot his temperature spiked, and he broke out in a rash. One woman in Manitoba died and her seven-year-old daughter became ill after receiving the vaccine.
Still, health officials have stressed the benefit of vaccine far outweighs any risk associated with being immunized.
