The most common reactions reported in the vaccine rollout so far are soreness in the injection area, headache, fatigue, muscle pains, chills, fever, ‘flu-like’ symptoms, nausea, dizziness, weakness and rapid heartbeat.
These reactions were usually resolved within a day or two, according to MHRA.
A spokesperson for the regulatory body explained: “In clinical trials, adverse reactions were generally milder and reported less frequently in older adults, which probably reflects the fact that younger adults tend to mount a stronger immune response to vaccines in general.
“This is also reflected in the Yellow Card reports (feedback from people who have taken the vaccine).
“This is not unusual, and the types of side effects is generally the same across the age range, even if reported more frequently in younger adults.”
