What is an unusual clinical manifestation?
A unusual clinical manifestation
according to the Public Health Agency of Canada, means any untoward medical event which occurs following the administration of a vaccine and which does not necessarily have a causal link with the vaccine. It can be an unfavorable or unexpected sign, an abnormal laboratory result, a symptom or a disease.
Pain at the vaccine injection site, redness or mild fever are considered by Health Canada to be unusual clinical manifestations
.
According to Health Canada, a serious adverse reaction to a marketed health product is defined as an harmful and unintended reaction
which requires or prolongs hospitalization, results in a congenital malformation, persistent or significant disability or incapacity, results in death or is life-threatening. This includes anaphylaxis, which is a severe allergic reaction.
