Rsv vaccine has brought back our sad baby

Will this ever end? We were just starting to feel like things were getting better, our little girl was happy more days than not and then we had the two month vaccines (a bit late because of Christmas) and she’s back to screaming most waking moments.

She’s refusing to eat, it makes her scream and arch her back. We’ve given her paracetamol four times now (baby paracetamol suppository) and it only works for the first four hours and the pain comes back but she has to deal with it for two more hours because of the dose.

Edit: to clarify I’m not saying people shouldn’t get their children vaccinated, it’s a very useful tool and unfortunately there’s side affects. I was asking for advice on what’s normal as our Dr didn’t warn us and all I can find online is it might make them more fussy. My daughter’s been screaming in agony at exactly the point the paracetamol wears off. I wanted to know if this is normal, how long it might continue and if others had a similar experience. I am if ours worried about intussusception, (being a terrible neurotic) and will speak to doctor on Monday if it’s not improved.

Edit: I mean rotavirus, thought that was shortened to rsv.
