Allergy cases emerge in California with batch of Moderna’s Covid vaccine

Moderna is co-operating with California’s investigation into several cases of possible allergic reactions among people who received its Covid-19 vaccine, the company said Tuesday. California State Epidemiologist Erica Pan recommended providers withhold shots from one batch of Moderna’s vaccine “out of an extreme abundance of caution”. The recommendation came after the state received reports of several people experiencing serious allergic reactions following immunisation from the same batch, a higher-than-usual number, Pan said in a statement. About 1 in 100,000 people have had a severe allergic reaction to Pfizer and BioNTech’s vaccine, which uses similar technology as Moderna’s shot, the US Centers for Disease Control and Prevention said earlier this month.
