Vaccine & subsequent fever - do I need to test/isolate?

[Gladly]

Had 1st dose of vaccine yesterday morning, was a bit achey and fatigued through the evening and took some paracetamol.
Have woken up pretty much on the dot of the paracetamol wearing off with bad body aches and feeling freezing cold - took some more paracetamol, layered up, put the heating on, felt generally very sorry for myself.
Took my temp which was 38.2 - still 38.2 now long after paracetamol back into my system.

I'm confident this is a vaccine side effect - but can any one point me in the direction of info on whether I am supposed to self-isolate/get tested? I'm a key worker and working outside the home - although unlikely tomorrow anyway given how I currently feel.

(Can't find answer myself on google but this could be that my brain is very foggy - apologies if it's obvious!)

I had exactly the same reaction- vaccine was at 11:30 the Friday morning, by 6pm I felt unwell and that night I had a raging temperature, aching, shivering and a rash. My colleague who had his at the same time was exactly the same but had recovered by Saturday morning. Both of us initially put down to side effects of the vaccine- he carried on as normal.

In my case, this continued all weekend with additional loss of appetite.
I'm front line worker and was too unwell for work on the Monday. Work arranged a test for me based on the high temperature- but it came back negative.

Turned out I had a kidney infection- I'm still not sure if that Friday night was coincidence or what.

Perhaps see how you are in the morning and take it from there. The info leaflet did clearly state that these could be side effects but that would be very short lived.

No harm in getting tested just incase though... Hope you feel better soon.

I had exact same symptoms. It was side effects from the vaccine.
I didn't feel any symptoms until the early hours next day and they lasted for a full 48 hours.
Fever, aches and pains, shivering, no energy, falling asleep without knowing it through out the day.

It's crap but I think it's 100% side effects.

I also had covid in November and the symptoms of that lasted over a week. It was bloody awful

The problem is it could be a complete coincidence. I think you still need to isolate and test.

I'm a vaccinator. Official advice is that if you still feel unwell, or have a temperature after 48 hours, then to follow government guidelines, self isolate and book a test.
Anything up to 48 likely vaccine effects. Anything after that likely you've inadvertently picked up Covid.
There are no live (or otherwise) strains of covid in the vaccines, so you cannot get Covid from vaccines. Hope that's clear

@nevertakeabreak thanks that's great to have clarified!
