CDC表示：新冠疫苗的严重过敏反应是流感疫苗的10倍，但依然比较罕见

CDC周三表示，新冠疫苗导致的严重过敏反应，明显高于美国人首次接种的其他疫苗。但CDC表示此严重过敏反应还是比较罕见，有190万人在去年12月中下旬接种了辉瑞新冠疫苗，其中有21例出现过敏性休克，或发生严重过敏反应危机生命。在经历严重过敏反应的21人中，其中17人有过敏史。研究还发现，这些人中有7人有过敏性休克的历史。

这些数据也意味着，每百万接种疫苗的人中大约有 11 人将可能经历过敏性休克，根据 CDC 数据，此风险大约比流感疫苗高10倍。

The CDC said on Wednesday that the severe allergic reaction caused by the coronavirus vaccine was significantly higher than other vaccines that Americans received for the first time. However, the CDC said that this severe allergic reaction is still relatively rare. 1.9 million people were vaccinated with Pfizer's coronavirus vaccine in mid-to-late December last year. Among them, 21 cases suffered from anaphylactic shock or severe allergic reactions threatened their lives. Among the 21 people who experienced severe allergic reactions, 17 of them had a history of allergies. The study also found that 7 of these people have a history of anaphylactic shock.

These data also mean that approximately 11 out of every million people vaccinated will experience anaphylactic shock. According to CDC data, this risk is approximately 10 times higher than that of the flu vaccine.  source
