Allergic reactions are an unlikely but real risk with both vaccine. A CDC report just lately launched final week confirmed 4,393 antagonistic reactions out of 1.9 million Pfizer doses administered — 0.2%, as of December 23rd, Of these, 21 have been extreme sufficient to depend as anaphylaxis — 11.1 circumstances per million doses. 17 of these sufferers had a historical past of allergic reactions.
