Hello, My Daughter Has A Pimple Like Mark On Her

Hello, my daughter has a pimple like mark on her leg actually three on one and one on the other, and one on her arm. She had the chicken pox shot when she was a year two months ago. Is it chicken pox or a rash? She has no symptoms. She did cough a little yesterday and today but that's all. She has no fever and is acting normal. They are red hard and fluid filled. Most are at least.
Thank you!
