Boston doctor develops severe allergic reaction to Moderna COVID vaccine

A doctor in Boston -- already suffering from a shellfish allergy -- developed a severe allergic reaction after receiving Moderna’s coronavirus vaccine on Thursday.

According to a report published in The New York Times, 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.

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

A spokesman at the Boston Medical Center, said in a statement on Friday that 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.
