An Alaska healthcare worker suffered a serious allergic reaction after receiving Pfizer’s coronavirus vaccine on Tuesday, a new report claims.

Three people familiar with the matter told The New York Times that the person was hospitalized and was in stable condition as of Wednesday morning.

The worker allegedly had no history of allergies to any medication but it’s unknown if he or she had any other allergies.

The allergic reaction is believed to be similar to the anaphylactic-like reactions suffered by two healthcare workers in Great Britain, both whom have since recovered, after they were given the Pfizer-BioNTech SE vaccine.

With hundreds of thousands of Americans expected to be dosed in the U.S. over the next few weeks, health officials will be on the watch to see if any other recipients experience severe reactions.

‘We don’t yet have all the details of the report from Alaska about a potential serious allergic reactions but are actively working with local health authorities to assess,’ a Pfizer spokesperson told CNN.

‘We will closely monitor all reports suggestive of serious allergic reactions following vaccination and update labeling language if needed.

‘The prescribing information has a clear warning/precaution that appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following the administration of the vaccine.’ has reached out to Pfizer for a request for comment. 

Anaphylactic shock is a severe and potentially life-threatening reaction to an allergy from food, medicine or even a type of material.

The immune system releases chemicals that flood the body, blood pressure suddenly drops, and airways narrow, which prevents someone from breathing normally.

Symptoms usually occur within minutes and include hives, a weak pulse, nausea, vomiting, dizziness and a swollen tongue or throat. 

If not treated immediately, it can lead to death. 



British regulators are advising that anyone who has a history of ‘significant’ allergic reactions to medicines, food or vaccines should not get the Pfizer coronavirus jab.

Allergic reactions to the vaccine are ‘very rare’, according to the trials involving more than 40,000 people.

Pfizer found a ‘very small number’ during its phase three clinical studies, or 137 out of 19,000 people who got the vaccine. But 111 people who were given a placebo also had allergic reactions. 

They also identified 12 possible side-effects from the vaccine, with seven identified as ‘very common’ meaning they are likely to affect more than one in ten people. Below are the known side effects.

The patient safety leaflet for the vaccine cautions that anyone with an allergy to any of the active substances in the vaccine should not receive the jab.

Allergic reactions to the vaccine are:

Very common (Likely to affect more than one in ten people)

Pain at injection siteTirednessMuscle painChillsJoint painFeverHeadache 

Common (Likely to affect up to one in ten people)

Injection site swellingRedness at injection siteNausea 

Uncommon (May affect one in 100 people)

In the U.K., two National Health Service (NHS) staff members with a history of severe allergies suffered reactions after being immunized.

One of the workers, a 49-year-old woman, had a history of egg allergies and the other, a 40-year0old woman, had a history of drug allergies. 

Both of them carried devices that contain epinephrine, a hormone that relaxes the airway muscles, in case they suffered any reactions.

A third patient also had a ‘possible allergic reaction,’ but British authorities did not describe it not give an update on the patient.

Pfizer says its jab is not made with any egg ingredients. 

After the reactions, the U.K.’s Medicines & Healthcare products Regulatory Agency (MHRA) issued a warning that anyone with severe allergic reaction to food or medicine not be given the vaccine. 

No such warning has yet been issued in the U.S.

About 32 million Americans have food allergies, according to the Asthma and Allergy Foundation of America. It’s unknown how many have drug allergies.

In fact, last weekend, the Centers for Disease Control and Prevention said Americans people with serious allergies can be immunized as long as they are monitored for 30 minutes after getting the shot. 

However, the Food and Drug Administration (FDA) is requiring Pfizer to monitor for anaphylaxis in the U.S. and submit data, The Times reported.  

The agency has also advised people with allergies to consult with their physicians to ensure they are not allergic to any components of the vaccine. 

In a preliminary analysis of Pfizer’s vaccine posted online last week, prior to FDA approval, a group of scientists said the jab was safe. 

Among 20,000 volunteers, 137 given the shot had allergic reactions but so did 111 people who received the placebo.

This led researchers to dismiss the theory that the vaccine was a potential hazard. 

Four people given the vaccine were diagnosed with Bell’s Palsy, a type of facial paralysis.

However, trial scientists said there was no evidence the jab that caused the condition and that the figure was on par with the rate of Bell’s Palsy in the general population. 

‘Among non-serious unsolicited adverse events, there was a numerical imbalance of four cases of Bell’s palsy in the vaccine group compared with no cases in the placebo group, though the four cases in the vaccine group do not represent a frequency above that expected in the general population,’ the analysis read.
