The Oregon Health Authority is recommending use of nearly 27,000 doses of the Moderna coronavirus vaccine despite reports in Oregon and California of a small number of adverse reactions among people inoculated from the same batch of the vaccine.
State officials said Wednesday they are heeding guidance they received from the Centers for Disease Control and Prevention, which “does not recommend health departments stop administering this lot or any lot of Moderna’s COVID-19 vaccine.”
State officials did not say when they received that guidance from the CDC about Moderna’s vaccine lot 041L20A, a batch of about one million doses distributed nationwide.
California on Sunday halted inoculations from that batch out of “an extreme abundance of caution” after fewer than 10 people “appeared to be experiencing a possible severe allergic reaction” at the same vaccination clinic.
Oregon is investigating two adverse reactions among people vaccinated from the same lot.
Oregon has received 57,400 doses from that batch across 118 locations, according to state officials. As of Wednesday, 26,567 remained locally.
“Adverse reactions to vaccines are extremely rare, but we’re paying close attention when they do occur,” Dr. Dean Sidelinger, the state health officer and state epidemiologist, said in a statement. “At this time, there’s no evidence that these events have been associated with any other vaccine site and I encourage every eligible Oregonian to get a vaccine as soon as vaccination is available to you.”
As of Tuesday, Oregon reported administering 225,066 doses of either Moderna or Pfizer coronavirus vaccine.
State officials did not immediately respond to questions about the two adverse reactions reported for Oregonians vaccinated with the Moderna lot now under scrutiny. Officials also did not immediately say how frequently adverse reactions are reported from the vaccine.
But a federal database updated last Friday lists 51 events in Oregon tied to the Moderna coronavirus vaccine. That includes six reports of headache, and two reports each of labored breathing, nausea, abnormal feelings, throat pain, pain or tremor.
Oregon has recorded 246 adverse events tied to the Pfizer coronavirus vaccine, according to the federal database.
State officials on Wednesday encouraged vaccine administrators to disclose lot numbers in response to questions from patients and reiterated the expectation of monitoring patients for 15 to 30 minutes after administering the coronavirus vaccine.
