To worry about my daughter's arm after vaccinations?

[dreamer24]

My daughter (3) had her preschool vaccinations on Wednesday. Today at bath time her arm looked like this (photo attached). Is this normal or do I need to get her seen by a doctor? She doesn't seem to be in pain with it, it's just very red and spreading. (So as not to drip feed, I have quite significant health anxiety so I do tend to worry about her a lot).

Anyone??

I think if it was a serious reaction it would have started within half an hour and been obvious. If you google "Immunization Reactions"
a typical answer is "Shot sites can have swelling, redness and pain. Most often, these symptoms start within 24 hours of the shot. They most often last 3 to 5 days"

I wouldn't worry unless it spreads a lot more and becomes painful. But I am not an expert...

Usually just a small round plaster but did they put a bigger one on? My DD reacted to the plaster after her jabs, no idea why and never happened again.

No it was just a small plaster she had on afterwards. And that came off 48 hours ago so I doubt it would be that? This is a bit of a delayed reaction.

Not wanting to scare you as you say you have HA but my son got cellulitis from his preschool booster. It swelled and spread over a few days.
Draw a line around the red patch and if it grows I’d get it looked at. Is she otherwise well?

Yes normal. This happened to me after covid vaccine. I called the doctor who told me it was just a reaction to injection site but nothing to worry about.

I think I was told to take antihistamine for the itchiness.

Normal to have a localised reaction to some vaccines. I always get this from tetanus and typhoid but not from the flu jab or covid.

I'm guessing you aren't old enough to remember the bcg vaccine for TB that used to be given in high school. That one was very prone to filling with pus 🤢 and creating a big welt.

I would do what @PiggieWig said, draw a line around the red. If it stays the same or reduces tomorrow I would think it’s fine, if it spreads further I’d get it checked.

That's still given to kids in Ireland, it generally becomes a pus filled lump that stays like that for a few months. Very unnerving!

How’s she doing OP?
