This is interesting, over 3 to 4 million people in the USA carry an epipen for severe reactions and 50 million have allergies. I wonder how many in Canada?
This is a concern...
The reaction seems to be puzzling scientists because people with allergies were tested in trials.....so maybe the reaction is from something else?
They are now checking with Pfizer to see if they had those with severe allergies included in the trials or if it was just less severe allergies.
British regulators advised people with severe allergies not to take Pfizer vaccine. One US researcher says that would be a 'showstopper' here.
