On October 23, AOA's Seolhyun uploaded a video on her personal YouTube channel. Here, Seolhyun revealed a vlog documenting her day of receiving her 2nd dose of COVID-19 vaccine.

Three hours after receiving her vaccine, Seolhyun turned on the camera to tell viewers, "My arm is completely stiff so it's so difficult to even lift up to here." Then, after eating dinner and getting ready for bed, Seolhyun revealed, "Not only does my arm hurt, but my armpit area also hurts. Even my ribs hurts. I don't know why, but it hurts so much that I can't sleep. I can't lie on my right side, and when I try to lie on my right side and move even a little, it hurts so I can't sleep." 

Seolhyun then updated her viewers a day later, and stated that thankfully, her pain was endurable to some extent and told viewers, "I hope when you all receive your vaccine, your side effects pass by well."
