More than 1,000 New Brunswickers have had an adverse reaction after getting a covid-19 vaccine, and more than a quarter of them were considered “serious,” according to the Department of Health. A total of more than two million vaccines have been administered in the province, putting the incidence at roughly 0.06 per cent.
Spokesperson Adam Bowie did not provide any information about the nature of the reactions, but the Public Health Agency of Canada defines an adverse event as “any untoward medical occurrence which follows immunization.” It isn’t necessarily causally related to the vaccine.
The adverse event may be any:
Unfavourable or unintended sign (for example: skin rash).
Abnormal laboratory finding.
Symptom.
Disease.
An event is considered serious if it:
Results in death.
Is life-threatening, such as anaphylaxis, a severe allergic reaction.
Requires in-patient hospitalization or prolongation of existing hospitalization.
Results in persistent or significant disability/incapacity.
Results in a congenital anomaly/birth defect.
Bowie did not provide a breakdown of reactions by type of vaccine or by ages, either. Earlier this month, the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) reported a possible link between ischemic strokes in people aged 65 and older and the Pfizer-BioNTech covid-19 bivalent vaccine, which is designed to target the omicron subvariants BA.4 and BA.5.
