Side effects from booster

[dogaibu]

I had my booster yesterday around 3pm and was feeling fine until around 5 hours ago when I started feeling chilly and achey with a headache. Can side effects take that long? Or is it more likely to be something else?

Had mine at 6pm on Mon. By bedtime I started feeling really cold to the point I had a hot water bottle in bed. Also had pain in my armpit which is apparently normal! Woke up at 5am and took some paracetamol and went back to sleep.
Felt run down, achey and drained yesterday. DH and I (boosters the same time) struggled to entertain DS between us. We had lots of fluids, alternated paracetamol and ibuprofen to keep the worst at bay.
Today I’ve kept up with the paracetamol and ibuprofen but felt ok. Managed to do dinner, look after a toddler all day etc but have a bit of that run down feeling.

I think it can take a few hours to start hitting you. Hope you feel better soon.

Mine didn't kick in properly until about 24 hours ish
