Poorly after jabs but not booster

[ChristmasAtHogwarts]

As the title says really I had my first and second jabs early although with a slightly longer gap than 12 weeks due to pregnancy and I was poorly after both with chills muscle ache and a headache
Just had my booster and had no side effects at all. Does that mean anything? I suppose I’m worried the booster hasn’t worked or been given properly as I had literally no side effects after being poorly the first time and second time.

Did you have a different type of vaccine?

Not unusual at all. Same one - your body is used to it now. Different one - not surprising. DS had the same with 2 AZ + Pfizer.

I thought the same then 2 days after booster felt unwell for maybe 24 hours, am feeling better now just a bit tired and achey.
Had a neg pcr so guessing delayed booster side effects.

Am so very glad I had it though.

Couple of questions - what combination of vaccines have you had? When you say ‘just had’ do you mean literally today?

If it’s your first dose of an MRNA one I wouldn’t expect to feel many, if any side effects; it tends to kick in on subsequent doses. If you’ve literally just had it, ime side effects start really kicking in around the 18-24hr mark if you’re going to get them at all.

It was last week, just over a week ago now. Had pfizer for all 3.
