Cases of serious allergic reactions to Moderna’s covid-19 vaccine are “rare” and were limited to just ten of the more than 4 million who received first doses in the United States, health authorities said Friday.
None of these ten cases resulted in the death of the vaccinated person.
According to these preliminary checks, anaphylactic shocks (severe allergic reaction, ndlr) after injection of Moderna’s Covid-19 vaccine are a rare occurrenceThe Centers for Disease Control and Prevention (CDC) said in a note.
The main federal public health agency in the United States operates between December 21, 2020 and January 10 108 cases reported as allergic reactions to 4,041,396 first injected doses.
The final evaluations showed that only ten cases were anaphylactic reactions, six of which resulted in hospitalization and the other four were treated by the emergency services.
This represents 2.5 anaphylactic reactions per million injections, much less than the Pfizer vaccine, according to a previous CDC study, that was a level of 11.5 per million inoculations.
Nine out of 10 affected people had a history of allergic reactions, for example, to drugs or food, but not after receiving vaccines.
Symptoms appeared within 15 minutes after injection in nine of the cases and within half an hour in the remainder.
These are ten women between the ages of 31 and 63.
Most of the people who had allergic reactions to the Pfizer vaccine were also women, but this may be due to the fact that two-thirds of those vaccinated with the first dose of the product from that lab were women.
The infrastructures where vaccinations have been performed are equipped to deal with severe allergic reactions and transfer patients to hospital if necessary, the CDC said.
