Medicine in the United States developed a severe allergic reaction after receiving the modern vaccine

Medicine in the United States developed a severe allergic reaction a few minutes after receiving the modern Crohn’s vaccine. This is the first reported case of this type of reaction associated with the modern vaccine. Responsible organizations are reviewing at least six cases of anaphylaxis in the first few weeks of distribution in the United States after receiving the Pfizer or Bivantek vaccine, which contains similar components.

Officials from the Food and Drug Administration and the US Centers for Disease Control and Prevention have been discussing reactions to some Pfizer vaccines; But it has not yet been determined whether part of the vaccine has caused allergic reactions. Earlier this month, several British healthcare workers developed anaphylaxis after receiving the Pfizer vaccine.

Thursday’s new event about Dr. حسین صدرزاده It so happened that he is an oncologist and aging specialist at Boston Medical Center and is extremely sensitive to oysters. In an interview, Dr. Sadrzadeh said that almost immediately after receiving the vaccine, he had a severe reaction and felt dizzy and his heart rate increased. David Kibe, A spokesman for Boston Medical Center confirmed in a statement that Dr. Sadrzadeh had received the modern vaccine on Thursday.

The statement said that Dr. Sadrzadeh felt that he was experiencing an allergic reaction and that he was allowed to use his own epipenin (automatic epinephrine injection device). He was taken to the emergency department, where he was evaluated and treated, and his condition was monitored and he was released as his condition improved.

Ray JordanA modern-day spokeswoman said Thursday evening that the company could not comment publicly on an event. On Friday, he added, the company’s medical safety team will investigate the matter and refer further questions to officials at the US Covid 19 vaccine program. The FDA did not comment on the new report. به‌گفت‌ی Tom SkinnerSpokesperson for the Centers for Disease Control and Prevention’s response to the new vaccines will be available on the Agency’s website from next week.

the doctor Marin CorovillaAn allergy and immunology specialist at Emory University said that given that more than 1.1 million people across the country have been vaccinated, multiple allergic reactions are a rare occurrence and should not put people at high risk of getting the vaccine. Refrain.

Following the occurrence of allergic reactions associated with the Pfizer vaccine, the Centers for Disease Control and Prevention recommended that Pfizer and Modern vaccines may not be appropriate for individuals with a history of anaphylaxis to vaccine components.

Anaphylaxis, which usually occurs within minutes of exposure to a stimulant, can impair respiration and cause a severe drop in blood pressure that is potentially life-threatening. The agency recommended that people with other allergies can get the vaccine; But after receiving the vaccine, wait 15 minutes at the vaccination site. People who have previously had an anaphylactic reaction to substances such as other vaccines or injectable drugs should be monitored for a further 15 minutes.

Regarding the case on Thursday, Dr. Sadrzadeh said that due to severe allergies, he had brought an automatic epinephrine injection device with him to the vaccination site. He said that a few minutes after the vaccine was given, his heart rate reached 150 beats per minute, which is almost twice the normal heart rate, and his tongue became tingling and numb. It was not long before he was drenched in cold sweat and felt dizzy and faint. His blood pressure also dropped dramatically. He noticed that his immune system was upset. “This was the anaphylactic reaction I experience with oysters,” said Dr. Sadrzadeh.

Dr. Sadrzadeh used his epipene and was taken to the emergency room on a stretcher, where he was given various medications, including steroids and benadryl (diphenhydramine) to calm his immune system. According to his medical record, he received shortness of breath, dizziness, palpitations and anesthesia after receiving the Covid vaccine. Four hours later, Dr. Sadrzadeh was released and had been recovering since Friday morning; But yesterday’s events shocked him. “I do not want anyone to experience it,” he said.

Pfizer and modern vaccines are the only vaccines that have so far been approved for emergency use in the coronavirus world, and mainly health care workers are given priority for the vaccine. The modern vaccine, like the Pfizer vaccine, is based on a molecule called messenger RNA (mRNA) that is injected into the arm. The mRNA molecule directs the production of the virus spike protein, which begins when the vaccine is injected into the body and trains the immune system to detect and stop it when exposed to the corona virus. Each vaccine contains other components that protect fragile mRNA and help stabilize it.

None of the components in the vaccine are known to be common allergens; But some experts have cited polyethylene glycol, or PEG, as a possible cause in both guidelines. Polyethylene glycol is found in a number of pharmaceutical products, including ultrasound gels and laxatives and injectable steroids, and allergies to them are very rare.

Dr. Korovilla said there was a possibility that another factor may be causing this, and that more research is needed to determine the cause of these events. the doctor Kimberly Bloomth, An allergist and immunologist at Massachusetts General Hospital noted that it is sometimes difficult to confirm anaphylaxis without a blood test to measure the enzyme tryptase released in allergic reactions. He added that protocols should be established to review similar materials.

Based on data from last-stage clinical trials, Moderna did not report an association between the Covid 19 vaccine and anaphylaxis; But when such carefully monitored products are widely available, rare side effects may occur. Recent allergic reactions to the Pfizer vaccine have been the subject of debate in meetings of experts from the Food and Drug Administration and the Centers for Disease Control and Prevention, with some saying that anaphylaxis appears to be uncommon in the Pfizer vaccine. Normally, the frequency of allergic reactions to vaccines is thought to be about one in a million.
