However, like many things in life, it's not over till it's really over.

Isolated incident?

The Pfizer-BioNTech’s COVID-19 vaccine has started being distributed to people all around the world.

While that might sound like a good thing, some people reportedly are having serious allergic reactions to the vaccine.

According to the News York Times, two health care workers in a hospital in Alaska suffered a serious allergic reaction just minutes after receiving the vaccine.

The first worker, a middle-aged woman who had no history of allergies, reportedly had an anaphylactic reaction just ten minutes after receiving the vaccine on Tuesday (15 December).

The woman reportedly experienced a rash over her face and torso, shortness of breath and an elevated heart rate, and she was moved to the intensive care unit.

She was hospitalised until last Thursday (17 December).

The second worker, meanwhile, developed eye puffiness, lightheadedness and a scratchy throat 10 minutes after the injection.

But thankfully for her, the symptoms subsided just an hour after receiving treatment.

“We don’t yet have all the details of the report from Alaska about a potential serious allergic reaction but are actively working with local health authorities to assess.

“We will closely monitor all reports suggestive of serious allergic reactions following vaccination and update labelling language if needed,” a Pfizer spokesperson was quoted as saying by The New York Times.

The clinical trial will involve 44,000 people, and people with a history of allergic reactions are not included in the list.
