Well I’m a contrarian. After my first Pfizer jab I had pretty much my standard response to all my previous vaccinations - bit of a sore arm for a couple of days and feeling just a little bit ‘off’. Not enough to stop me doing anything though. After my second Pfizer jab, nothing, nada, zip, nil symptoms. Didn’t even know I’d had it.
Interestingly though, I did have this years flu shot 16 days after my second Pfizer and I did know I’d had that. Ever muscle ached for about two days. Nothing significant, but enough that I couldn’t get comfortable in bed and had two restless nights sleep.
