Covid19 vaccination

Ten people โ€” all women โ€” experienced the potentially deadly allergic reaction after receiving their first dose of the shot, with nine cases reported within 15 minutes of vaccination.That statistic was out of more than 4 million doses administered between Dec. 21 and Jan. 10 and equates to 2.5 cases per million doses given, or 1 case per 400,000 doses, the agency said.Nine of those who fell ill had a history of allergies or allergic reactions, including five who had a previous history of anaphylaxis.Among the eight people with follow-up information available, all had recovered or been discharged.No anaphylaxis-related deaths were reportedMore women than men have received the first dose of Moderna โ€” which could explain the unusual finding that all 10 patients who had an anaphylactic reaction were women, the CDC explained.The reaction requires immediate treatment, typically a shot of epinephrine. If left untreated, it can be deadly. A total of 1,266 patients receiving their first Moderna dose experienced โ€œadverse events,โ€ such as a rash or respiratory problems, the agency said.In December, a health care worker in Alaska was hospitalized after receiving the Pfizer/BioNTech coronavirus vaccine and experiencing an anaphylactic reaction โ€” which has also been reported in the UK.โ€œA strong female predominance of anaphylaxis case reports exists for both vaccines,โ€ the CDC noted in its Friday report.โ€œFinally, many persons experiencing anaphylaxis after receiving either vaccine had a history of allergies or allergic reactions, with several having experienced an anaphylaxis episode in the past.โ€
