Anyone's teen felt terrible after second vaccine?

[Neolara]

My 15yo D's had his second vaccine (Pfizer) at the weekend and had a temperature and felt pretty bad for 48 hours. I'm surprised because he was completely fine when he had the first vaccine and also when he actually had covid over Xmas. My other two also had had no reaction to the jabs and very mild covid symptoms. None of my friends had mentioned their teens feeling unwell after the vaccine.

I felt terrible after both vaccines in exactly the way he was feeling bad. But I am old! I know side effects are normal, but hadn't seen or heard about it in teens. Anyone elses teen had a unpleasant reaction?

My DS12 had quite a nasty reaction to his first vaccination – he only had it in January as he had Covid in October so needed to wait 90 days.

His symptoms after vaccination were high fever, bad headache and generally feeling awful. He said he felt the same as when he had Covid, but it probably didn't last quite as long.
