A doctor in Boston with a shellfish allergy developed a severe allergic reaction after receiving Moderna's coronavirus vaccine on Thursday, the New York Times reported on Friday, 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 NYT reported.

It is the first severe reaction publicly linked to Moderna's vaccine

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.
