CDC reports more allergic reactions to Covid-19 vaccines, but cases remain few
Twenty-nine people in the United States have developed anaphylaxis after being vaccinated against Covid-19 since the vaccine rollout began, health officials reported Wednesday, with cases occurring after vaccination using both the Pfizer-BioNTech and the Moderna vaccines.
The Centers for Disease Control and Prevention said the allergic reactions do not change its recommendations on who can be vaccinated against Covid-19, with senior officials stressing that the risk of severe illness and death from the disease still outweighs the risk of developing anaphylaxis after vaccination. An early assessment by CDC scientists suggested anaphylaxis occurred at a rate of about 11.1 cases per 1 million vaccine doses in the first week and a half of the vaccine program.
