A worker in Boston with a history of allergies developed an allergic reaction after receiving a Moderna Covid-19 vaccine on Christmas Eve.
This is the first known case of an allergic reaction to a Moderna coronavirus vaccine, although at least six cases of allergic reactions have been reported in the US associated with the Pfizer / BioNTech vaccine.
“After I received the vaccine, I felt tachycardic, but I felt it was anxiety because I was scared after learning about Pfizer’s reactions in the US, especially with those people who have allergies to shellfish, like me, “Dr. Hossein Sadrzadeh told CNN.
Tachycardia is a medical term that describes rapid or irregular heartbeats.
After his vitality was checked, Sadrzadeh realized that his heart rate had increased.
“My heart rate was 150, my normal heart rate is 75, but … six, seven minutes after injecting the vaccine, I felt my tongue and also my throat, having a strange sensation of tingling and numbness that I had. I had it before in my shellfish allergy, “Sadrzadeh said.
Sadrzadeh said his blood pressure dropped so low that it was not even detectable with a monitor. Then he decided to use his EpiPen, and the staff rushed him to the emergency room.
Sadrzadeh was monitored for four hours before being able to drive home.
“The main concern for me, as a human being and as a doctor … I have to spread the word to people … People should have EpiPen with them if they have allergic reactions,” Sadrzadeh said, urging Moderna to investigate further.
A spokesman for Moderna said the biotechnology company could not confirm the incident, but “reported the potential adverse event through its internal safety reporting system and Moderna is still investigating.”
