12 week imms

Hi all,

My daughter is 15 weeks old and had her 12 week imms on Friday (these were late as we unfortunately had norovirus when she was due her 8 week ones, and so jabs were postponed)

She of course cried during the jabs and then we had some upset that night, but after some Calpol she eventually fell asleep and slept through the night - back to her normal self in the morning.

All been fine since then except today when I bought her into my mums house - she started screaming/crying when sitting on my mums lap and we couldn’t calm her for around half an hour at first. She would ease up slightly and even smile but would start crying so much again within a minute or so. She fell asleep on me, woke up after around 45 minutes, seemed fine (smiling, laughing) then after about 5/10 mins of being awake we were back to the inconsolable crying.

Have resorted to giving her some Calpol and she has now fallen asleep on me again - is this normal 4 days after immunisation or could it be something else? The nurse said there are not often side effects after the 12 week imms but I’ve also read side effects usually are only up to 48 hours after? She doesn’t seem hot (only when she was crying but think that’s because she was worked up, she cooled down once she fell asleep)

Sorry if this seems like a silly question but she is not often upset and her cry in general is particularly loud, she gets in a right state and panics me a little when she is under the weather!

I think it would be unusual for symptoms to start at 4 days so it could be that they have picked up a bug - possibly from being at the GP surgery getting the jabs!

The 12 week jabs don't have the menB which is the main vaccine from the newborn set that triggers a bit of a response in the body but really any of them can and it's kind of the point of the vaccines. Introducing a virus /bacteria in a safe ways for the body to detect it and make the antibodies so that if it does come across it again it has the specialist tools to fight it. I would expect that to have started before day 4. It's getting a bit late in the day otherwise I would say contact your GP surgery. Given the time I would monitor overnight, call 111 is you are unsure and get in with the GP in the morning
