Anyone with a history of severe allergic reactions should talk to their doctor before getting Pfizer-BioNTech’s COVID-19 vaccine.
That’s according to Health Canada, after at least two people had serious reactions to the shot in the U.K.
The agency says both of these people had severe, pre-existing allergies when they were immunized. Both also carried adrenaline auto-injectors, or EpiPens.
Those patients have recovered, but Health Canada says the incident raises questions about potential reactions to the vaccine.
At this point, the agency isn’t telling people with serious allergies to avoid the shot, unless they are specifically allergic to one of the ingredients.
However, they are strongly suggesting these people speak to their family doctor or health professional before rolling up their sleeve.
It’s also a good idea to consult your doctor about any existing allergies you may have.
Health Canada says all vaccines, not just those protecting against COVID-19, carry a warning about allergy risks. Clinics are prepared for these rare events, should they occur.
If any new safety issues arise, Health Canada says they will take immediate action.
