The CDC report confirmed that 21 cases had been reported for severe allergic reactions after Pfizer’s COVID-19 vaccine was administered in the U.S.
Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, said in a Jan 6 news briefing that the rate of anaphylaxis seen so far is 11.1 cases per 1 million vaccines. This rate is higher than the rates reported during flu vaccination, which is 1.3 cases per 1 million doses. The eight additional cases were announced in a press briefing that involved both the Pfizer-BioNTech and Moderna vaccines, but no further details were available.
Long-term sequelae of COVID-19 for a lifetime are currently unknown. However, persistent symptoms and serious complications are being reported among COVID-19 survivors, including persons who initially experience a mild acute illness.
CDC officials advised people with anaphylaxis history to alert the person administering the shot before taking it. The total number of recorded reactions in the U.S has grown to 29 cases. The first 21 anaphylaxis cases were reported after administering the Pfizer COVID vaccine. However, there is no transparency regarding how many were reported after the Pfizer vaccine or Moderna vaccines in additional cases.
