The first worker, a middle-aged woman who had no history of allergies, had an anaphylactic reaction that began 10 minutes after receiving the vaccine at Bartlett Regional Hospital in Juneau on Tuesday, a hospital official said. She experienced a rash over her face and torso, shortness of breath and an elevated heart rate.

Dr. Lindy Jones, the hospital’s emergency department medical director, said the worker was first given a shot of epinephrine, a standard treatment for severe allergic reactions. Her symptoms subsided but then re-emerged, and she was treated with steroids and an epinephrine drip.

When doctors tried to stop the drip, her symptoms re-emerged yet again, so the woman was moved to the intensive care unit, observed throughout the night, then weaned off the drip early Wednesday morning, Dr. Jones said…

The second worker received his shot on Wednesday and developed eye puffiness, lightheadedness and a scratchy throat 10 minutes after the injection, the hospital said in a statement. He was taken to the emergency room and treated with epinephrine, Pepcid and Benadryl, although the hospital said the reaction was not considered anaphylaxis. The worker was back to normal within an hour and released.
