據加通社報道,安省衛生局的Dr. Bryna Warshawsky表示,人們不該参考去年防流感數據,来決定今年是否打流感疫苗。每年2月,世界衛生組織會根據過去的資料決定秋季的疫苗成分。生產商需要六個月來準備疫苗,在10月中到底進行接種宣傳。而流感的流行期則在11月底到第二年早春。

根據加拿大公共衛生局(Public Health Agency of Canada)数据统计,加拿大醫院平均每年接受12500個病人,其中3500人因流感引起綜合症導致死亡。

去年疫苗失败原因为 H3N2 的病变。一般流感疫苗预防四种病毒:H3N2, H1N1,两种B淋巴细胞流感病毒(B-lineage influenza viruses),H3N2是最常见病毒,而去年H3N2由于变异导致疫苗不幸失效。
