Side effects, including headaches, fatigue, body aches, chills, and injection site pain, were mainly considered mild to moderate.
In at least two cases, however, volunteers had severe reactions.
One developed grade three fever, which is classified as 102.2 ° F (39 ° C) or above after receiving a low vaccine dose. Another developed fatigue was so severe that it temporarily halted daily activities, Anderson said.
Typically, side effects occurred soon after receiving the vaccine and resolving quickly, he said.
“This is similar to older adults experiencing high-dose influenza vaccines,” Anderson said. “They may feel or have fever.”
Norman Hulme, a 65-year-old senior multimedia developer at Emory who took a lower dose of the vaccine, said he felt compelled to participate in the trial after seeing the first reaction to fighting the virus in New York and Washington State.
“I really had no side effects,” said Hulme, who grew up in the New York area.
Hulme said he was aware that Modern’s vaccine had employed a new technique, and that there might be risk in taking it, but said “someone had to do it”.
