It hurt, but like any injection in your arm.
For S she cried when the needle went in, then was better. She had a sore raised patch on her arm for a few days. Overnight she had the shivers, but they went in an hour or so with paracetomol.
For me I had the red raised patch for over a week. The day after my jabs I also had the shivers and felt fluey, but it cleared up in 24h.
