Three days after the state paused the administration of 330,000 doses of Moderna’s COVID-19 vaccine due to reports of allergic reactions, California public health officials said there was “no scientific basis for continuing the pause.”
The previously suspected batch, Moderna 041L20A, was weekly doses to the state. Humboldt County Public Health has had 4,100 doses of this batch in its freezer and has already given some doses to locals, according to Dr. Jan Hoffmann, a public health official.
California state epidemiologist Dr. Erica Pan issued the following statement late Wednesday, advising providers they could resume use of the vaccine immediately:
Our top priorities are to ensure that vaccines are safe and effective and distributed evenly and efficiently.
As a precaution, we advised suppliers to pause the distribution of batch 41L20A for Moderna COVID-19 vaccine on Sunday evening. Yesterday, we convened a working group to review scientific safety in the Western States and additional allergy and immunology specialists to examine the evidence gathered. We had additional discussions with the San Diego Department of Public Health, the FDA, the CDC, and the manufacturer, and found no scientific basis for continuing the break. Suppliers who have paused the Moderna Lot 41L20A vaccine may resume immediately.
These findings must continue to reassure Californians that vaccines are safe and effective and that the systems put in place to ensure the safety of vaccines are rigorous and science-based. My family members who have qualified to receive the vaccine as health professionals or because of their age have already received the COVID-19 vaccine, and I encourage every Californian to take the vaccine when it is their turn.
