H1N1 Vaccine Safety in Manitoba, Canada

Many people worldwide received the monovalent adjuvanted H1N1 vaccine. However, very little is known about the safety of the vaccine, particularly beyond the first few weeks after vaccination. This study will combine data from a well-established immunization registry in Manitoba with data from hospitalization and physician records, to examine the safety of the vaccine in the six month period post-vaccination. Studies on vaccine safety are important as the public's perception of the safety of a vaccine has a major role in its uptake.
