US doctor has severe allergic reaction to Moderna’s Covid-19 vaccine: report
- A doctor in Boston said he felt dizzy and had a racing heart almost immediately after getting his vaccine shot, according to a New York Times report
- It is the first severe reaction publicly linked to Moderna’s vaccine, which is in its first week of a roll-out across the US

A doctor in the US state of Massachusetts with a shellfish allergy developed a severe allergic reaction after receiving Moderna’s coronavirus vaccine on Thursday, the New York Times reported this week, citing the doctor.
Dr Hossein Sadrzadeh, a geriatric oncology fellow at Boston Medical Center, said he had a severe reaction almost immediately after being vaccinated, feeling dizzy and with a racing heart, the Times said.
It is the first severe reaction publicly linked to Moderna’s vaccine, which is in its first week of a nationwide roll-out in the United States.
David Kibbe, a spokesman at the Boston Medical Center, said in a statement on Friday that Dr Sadrzadeh “felt he was developing an allergic reaction and was allowed to self-administer his personal epi-pen”.
“He was taken to the Emergency Department, evaluated, treated, observed and discharged. He is doing well today,” it said.
A US Food and Drug Administration official said last week that the agency was investigating around five allergic reactions that occurred after people were administered Pfizer Inc and BioNTech SE’s Covid-19 vaccine in the US.
