California health officials warned against the use of the Moderna’s coronavirus vaccine with caution of allergic reactions in people who have been vaccinated, CNN reported on January 18th.
Moderna reported that 37 lots had been delivered and most of them had definitely been used. During the first week of January, California got several of the samples sent out. According to the CDPH, less than 10 people out of hundreds of patients at a clinic in San Diego needed medical care within the span of 24 hours. No one that has administered the vaccine in some of the other 286 locations has shown the same allergic response.
Since no urgent substitute doses were needed, the California health department suspended the vaccination program.
Officials did not include specifics about the effects of the anaphylactic reaction, but did provide a connection to a US Centers for Disease Control and Prevention (CDC) page regarding anaphylaxis, a severe allergic reaction. Symptoms of anaphylaxis include fast heart rate, dizziness.
Dr. Paul Offit commented the state’s decision that California’s decision to hold back doses of vaccine carries its own risks, especially since allergic reactions can be monitored. Offit also said that the thing about anaphylaxis is that it is readily identifiable, and the cure is easy with epinephrine.
A lot of vaccinations were pulled from San Diego County’s supply. Santa Clara County said on Monday that there are no doses left and no vaccinations have been administered.
The investigation is being carried out by the CDC, FDA, and Moderna, and the state.
