TORONTO — In the fall of 2009, Canada launched its largest-ever vaccination campaign to protect against an outbreak of influenza A, or H1N1, with varying degrees of success. There were delays in production, supply shortages, and difficulties administering the new vaccine.
According to Statistics Canada, by April 2010, the majority of Canadians (59 per cent or 16.5 million people) had not been vaccinated against the H1N1 virus, which was also known as the “swine flu.”
The government agency said that a total of 428 Canadians died from H1N1 and thousands more were infected. Worldwide, there were more than 18,000 deaths from the virus.
