Commonly reported side effects of the COVID-19 vaccine include fatigue, headache, and muscle pain.
Fatigue has been reported by roughly 63 percent of research subjects who received the vaccine, while headache and muscle pain have affected about 55 and 38 percent of participants, respectively.
Smaller numbers of participants reported chills, joint pain, or fever following vaccination.
Participants were more likely to report such symptoms following the second dose of the vaccine.
Dr Matthew Heinz said: “[The reaction to the second dose] tends to be a little more of an intense response, which does make sense, considering your immune system has been exposed already.
“It gets hit with another dose of [the vaccine], and it has a sort of quicker and more robust response. That makes a lot of sense immunologically,” he added.
“Of course, we have to continue to monitor going forward.”
