The Pfizer antibody was connected to an expected 143 overabundance instances of stroke per 10 million, while Covid was connected to 1,699 abundance strokes.
Hippisley-Cox focused on that expanded dangers related with the punches were present moment just, while infection contamination was related with expanded danger for the entire of the 28-day time frame analyzed.
