Last week, when two British medical staff suffered anaphylactic shock after receiving the first dose of Pfizer / BioNTech’s new corona vaccine, local health experts warned that people with known severe allergic reactions should avoid the vaccine. Subsequently, the wording was revised to stipulate that anyone who has an allergic reaction to food, drugs or vaccines should not be vaccinated.
Health experts, including Dr. Anthony Fauci, spoke about this before the vaccine was introduced in the United States, explaining that such side effects are rare. Not all people with allergies will have this condition. Furthermore, the incident in the UK warned medical staff everywhere that this type of allergic reaction is possible, and a plan has been developed to alleviate any problems. The system was tested in Alaska and two vaccinated medical staff received emergency treatment after the injection.
The Pfizer / BioNTech phase 3 trial indicated that the drug is 95% effective, with short-lived and mild side effects. Pain at the injection site, as well as fever, fatigue, and headache are the most common. But none of the 44,000 volunteers had allergic reactions.
Anaphylactic shock is a life-threatening complication and the patient needs immediate treatment. People with a history of anaphylactic shock often take epinephrine injections, which they can inject themselves during an attack. Both British patients with anaphylactic shock had severe allergic symptoms. According to the New York Times, a 49-year-old woman had an egg allergy and a 40-year-old woman had a history of drug allergy. They all wear equipment similar to the EpiPen.
The allergic reaction was successfully prevented in Alaska. The two medical staff members said they did not want their experience to have a negative impact on the vaccination campaign. Of the two medical staff, only one has a history of allergies. She received the injection on Wednesday and developed symptoms such as puffy eyes, dizziness and itchy throat, which lasted for 10 minutes. He was treated with adrenaline, Pepcid and Benadryl in the emergency room. However, this reaction is not considered anaphylactic shock. Medical personnel returned to normal within an hour.
A middle-aged woman with no history of allergies developed an allergic reaction 10 minutes after the injection. He developed a rash on his face and torso, shortness of breath, and an increased heart rate. He received an injection of epinephrine and his symptoms disappeared. But then his symptoms reappeared and he received steroid and epinephrine infusions. When the infusion was stopped, symptoms reappeared and the woman was transferred to the intensive care unit for observation. By Wednesday morning, she no longer needed infusion therapy.
By Wednesday night, the hospital had received 144 doses of the new corona vaccine, and Alaska health officials announced they did not plan to change the vaccination schedule or course of treatment.
Dr. Paul Offit explained to the New York Times that there are appropriate preventive measures for such adverse reactions. Offfit is a member of the independent advisory group that recommended that the FDA authorize the emergency use of the Pfizer vaccine. The vaccinated person needed to stay in place for 15 minutes after the injection, which helped this woman in Alaska.
Dr. Jay Butler, an infectious disease expert at the CDC, told reporters that the situation in Alaska shows that the surveillance system has worked. The CDC recommends vaccination in an environment with oxygen and adrenaline to prevent allergic reactions. The following are CDC guidelines on the side effects of the new corona vaccine.
Health experts and Pfizer will monitor the situation and continue to collect data to determine what caused the allergic reaction. Offit told the New York Times that both the BioNTech and Moderna vaccines use mRNA materials encapsulated in oily molecules (lipids). A stable molecule called polyethylene glycol covers the lipid layer, which can trigger allergic reactions. This is just a guess, because more research is needed.
