Are there are serious risks with the adjuvanted vaccine?
No. There is no evidence to suggest that the adjuvanted vaccine is unsafe. Both vaccines have gone through extensive testing and review before being approved for use. However, there is no evidence available from clinical trials using adjuvanted vaccine in pregnant women or in children aged six months to three years. The adjuvanted vaccine provides much stronger protection, however the Government of Canada ordered 1.8 million doses of unadjuvanted vaccine to offer pregnant women, since adjuvanted vaccine has not been widely tested in this group. The decision to purchase unadjuvanted vaccine for pregnant women is based on a desire to err on the side of caution.
