Canada To Stop Using AH1N1 Vaccine
Canada advised its doctors to stop using a batch of AH1N1 vaccines after reports of severe side effects in some patients.
About 172,000 doses of Arepanrix made by GlaxoSmithKline (GSK) were recalled after six Canadians experienced anaphylaxis, which causes breathing problems, low blood pressure and swelling of the tongue, lips and eyes. This is condition can be fatal. The six patients are already cured and reported that they are not suffering from any long-term ill effects.
The World Health Organization (WHO) called the six cases as “an unusual number”. Normally, only one adverse effect out of 100,000 doses is expected. That makes the six cases five more than or five times the acceptable range.
The 172,00 vaccine batch in question was distributed to almost half of the country.
The WHO is still waiting for the final test results by GSK.
AH1N1 is a mixture of swine, bird and human viruses. It has killed at least 6,770 people globally.
