Severe allergic reactions to the modern vaccine are rare

Severe allergic reactions to the modern vaccine are rare

Severe allergic reactions to Moderna’s Kovid-19 vaccine are “rare” and affect only 10 of the more than 4 million first-dose administered in the United States, health officials said Friday.

None of these ten cases led to death.

“Based on these preliminary tests, anaphylactic shock (a severe allergic reaction) is a very rare occurrence after injecting Modrana’s vaccine against Kovid-19,” the Centers for Disease Prevention and Control (CDC) wrote.

The study by the country’s leading federal public health agency reported 108 allergic reactions injected in 4,041,396 first doses, from December 21 to January 10.

In fact only ten cases turned out to be anaphylactic shock, six of which required hospitalization (the remaining four cases were treated in the emergency department).

This represents 2.5 anaphylactic shocks per million injections. According to a previous CDC study, that rate with Pfizer’s vaccine was 11.1 shocks per million injections.

In ten cases, nine had a history of allergic reactions, for example to certain medications or foods, but not after the vaccine was injected.

Nine of them had symptoms within 15 minutes of being injected, and more than 30 minutes in one.

Notable fact: 10 of the participants were between 31 and 63 years old, all women. A similar prevalence has been observed for allergic reactions to Pfizer’s vaccine, although most women receive the vaccine dose (two-thirds to one-third of men).

Vaccination infrastructure must be set up to treat severe allergic reactions so that patients can be rushed to the hospital if needed, the CDC said.
