Moderna Inc is co-operating with US regulators to investigate several cases of possible allergic reactions among people who received its Covid-19 vaccine in California, the firm declared on Tuesday.
Earlier, A California-based epidemiologist Erica Pan recommended providers to withhold shots from one batch of the vaccine “out of an extreme abundance of caution”.
The recommendation came after the state’s health department received reports of several people experiencing serious allergic reactions following immunisation from the same batch, “a higher-than-usual number” as described by the epidemiologist.
Meanwhile according to US Centers for Disease Control (CDC): 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.
However, Moderna has issued a statement that it is “working closely” with the US Food and Drug Administration and CDC “to understand the clinical cases and whether the broad pause in use of the lot is warranted.”
