Adverse reactions to any vaccine can be expected, Dr. Anthony Fauci said Wednesday.
This comes after Alaskan state health officials confirmed Wednesday that a health worker suffered an adverse reaction to a vaccine Tuesday. They said she has been treated and is recovering.
“Well, that's the reason why I think people need to understand that the issue of the safety goes well beyond the confines of a clinical trial,” Fauci told CNBC.
“Because when you're in a clinical trial, you're giving it for example, the Pfizer trial was 44,000 people. Once you decide to dispense the vaccine widely, you're talking about millions and tens of millions and ultimately hundreds of millions of doses. So you may see reactions that you didn't see in the clinical trial,” added Fauci, who is director of the National Institute of Allergy and Infectious Diseases.
Alaska doctors said the health worker who suffered the reaction did not have a history of allergies.
