Boston: As coronavirus vaccination drive is in full swing across the US, the New York Times reported on Friday that a doctor in Boston with a shellfish allergy developed a severe allergic reaction after receiving Moderna’s coronavirus vaccine on Thursday, citing the doctor.

A geriatric oncology fellow at Boston Medical Center, Dr Hossein Sadrzadeh said he had a severe reaction almost immediately after being vaccinated, feeling dizzy and with a racing heart, the NYT reported.

It is the first severe reaction publicly linked to Moderna’s vaccine, which is in its first week of a nationwide rollout.

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.”

A US Food and Drug Administration official said last week that the FDA is investigating around five allergic reactions that occurred after people were administered Pfizer Inc and BioNTech SE’s Covid-19 vaccine in the United States.
