This is the first known case of an allergic reaction to the modern coronavirus vaccine, although at least six such cases have been reported in the United States involving the Pfizer / Bioentech vaccine.
“I felt tachycardic after I got the vaccine, but I thought it was probably worrying because I was scared after learning about Pfizer’s reactions in the US, especially with people with shellfish allergies like me,” said Dr. Hussein Sadrajadeh explained to CNN. Tachycardia is a medical term meaning fast or irregular heartbeat.
After checking his pandu, Sadrajadeh realized that his heart rate had increased.
“My heart rate was 1,150, my normal heart rate is 75 but … six, seven minutes after the vaccine injection, I felt a tingling and numbness in my tongue and also in my throat,” I was told first about my shellfish allergy. That was the reaction, “said Sadrazadeh.
Sadrazadeh said his blood pressure had dropped so low that it could not even be detected by a monitor. Only when he decided to use his epipane, and then the staff rushed him to the room, which was only a few minutes away from the room where he was after receiving the Covid-19 vaccine.
Sadrazadeh was monitored for four more hours after his allergic reaction and was then able to drive from home. He says medical center staff “responded exceptionally well.” Boston Medical Center was unable to provide any additional details, but confirmed Sadrazadeh’s involvement.
“The main concern for me as a man and as a therapist … I have to convey this word to the people … If people have an allergic reaction, people should keep an epinephrine with them,” Sadrazadeh continued, urging Modern.
Ray Jordan, a spokesman for the biotechnology company, told CNN: “Moderna could not confirm the incident, but has reported a potential adverse event through its internal security reporting system and Moderna is investigating the incident further.”
Which ingredient in the coronavirus vaccine can cause an allergic reaction in some people is still unknown. Dr Peter Marcus, head of the FDA’s Center for Biological Evaluation and Research, said in a briefing last week that the agency was investigating a compound known as polyethylene glycol (PEG), as well as four other possible components in the composition.
“It is known that one of the ingredients in both vaccines, polyethylene glycol, may be unusually associated with allergic reactions.” Polyethylene glycol is a compound that appears in many pharmaceuticals, including some intestinal preparations and laxatives. “He may be the culprit here. And that’s why we’ll be watching very closely when we see it because we’ve got the modern vaccine.”
Pfizer CEO Albert Borla explained in townhall on Thursday that adverse reactions to the vaccine are “very rare” in clinical trials. He pointed out that now that the vaccine is being distributed to millions of people, adverse events are inevitable. He added that these incidents should not prevent people from getting vaccinated, especially predisposing conditions that put them at risk for severe Covid-19.
On Wednesday, Monsef Slow, chief scientific adviser at Operation Operation Worm Speed, said there was a discussion between vaccine makers and national health organizations to consider a clinical trial of the Covid-19 vaccine in highly allergic populations, such as those that need to be taken. An epipan with them at all times. He said the trial could help understand the rate of allergic reactions and what it is provoking.
He had earlier told CNN’s Jack Tapper that the key was to keep in mind that allergic reactions could occur.
“If you prepare, there are these kinds of events that can be dealt with,” Sloe said. “And we will try and understand what is in the vaccine that motivates this, if there is something that motivates this that is certain.”
