Moderna’s vaccine against the coronavirus infection rarely causes severe allergic reactions, according to a new data released by the Centers for Disease Control and Prevention (CDC).
According to the report more than 4.04 million people have been given the Moderna coronavirus vaccine from December 21, 2020, to January 10, 2021, but only 10 have so far developed life-threatening allergic reaction called anaphylaxis.
That’s around 2.5 cases of anaphylaxis per 1 million people vaccinated with the Moderna coronavirus vaccine. A life- threatening allergic reaction that is anaphylaxis occurs rarely after vaccination, with onset typically within minutes to hours.
The author said in the report that, “Based on this early monitoring, anaphylaxis after receipt of Moderna Covid-19 vaccine appears to be a rare event.”
Nine out of 10 cases occurred among patients with previously known allergies so it is yet not clear what caused the severe allergies.
However, five of them previously had anaphylaxis and most had experienced allergies to various medicines too.
Of the 10 patients who showed severe allergic reactions, nine developed symptoms such as vomiting, nausea, wheezing, tongue swelling and rash within 13 minutes of getting the Moderna coronavirus vaccine. One volunteer developed symptoms within 45 minutes of getting the vaccine.
According to the report all the 10 volunteers were treated with epinephrine that had shown severe allergic reactions, while all patients recovered later.
During December 21, 2020-January 10, 2021, the administration of 4,041,396 first doses of Moderna Covid-19 vaccine (2,465,411 to females [61%], 1,450,966 to males [36%], and 125,019 to persons whose sex was not recorded [3%]) was reported to CDC
