Are anyone else’s children suffering nasal flu vaccine side effects?

Every year mine seem to have some kind of side effect. This year is diarrhoea. Any else’s household?
Mine had their vaccines 5/6 days ago.

Mine have never had side effects from the nasal flu vaccine. This year seems to be pretty bad for viruses already. My 3 have been absolutely riddled with colds and we’re not even out of October yet. Maybe it’s a coincidence? Especially as you said you’re not well either.

It could be a coincidence, but it also could be side effects from the vaccination as it’s well documented that some children will suffer side effects.

My kids ALWAYS get side effects from the flu spray. My siblings kids do too. Fevers, headaches, runny noses etc. Every year. I don't mind this, the side effects are "worth" the benefits but i wish they would be honest that lots of children will get side effects. DC2 used to have the non-live vaccine for medical reasons and did not get side effects with that.

What gets me cross is they know full well the spray "provokes a more robust immune response" which is why they give children the live nasal spray vaccine but do not give it to adults/the elderly.

Some people might be better off choosing to get their child the injection instead of live vaccine but they need honest information to make that choice.

The nasal spray is not licenced for adults. The nasal passages are thicker in an adult, so the spray wouldn’t be absorbed as well, and therefore not work like it does in children.
The injection is offered alongside the spray, so always an option, but the nasal spray is the most effective product for children in preventing flu.

My 2 little ones have had all their vaccines. This year though they both had there spray at two different times and both suffered with headaches, temps and rashes after. Diarrhoea is listed as a side effect for the person that said it was likely. My 6yr has had the above symptoms plus stomach upset. Dont feel bad for asking the question, I came on here to see if others were having an issue too. This is the first year the symptoms have been bad. Feels like the our school did it the last day of term for a reason....

It’s not the people who answer the questions, it’s the people who start the threads, and there are of course plenty of genuine threads too, like this one of course.
It’s good to be aware of the misinformation techniques being used against our country, I think. It’s our children and elderly relatives at risk, after all.

The answer to that though isn’t to pretend that no children get side effects, it’s to reiterate the actual facts. It’s a live vaccine, and a small percentage of children will experience side effects. These are usually mild, and short lasting.

I think diarrhoea would be a very unusual side effect OP. Much more likely it’s a bug sorry

Not that unusual. Mine always get diarrhoea when they have flu/colds

DC get it every year, never has side effects.

My youngest gets ill after it every year (varying degrees of cold/flu symptoms) the last couple of years she was so poorly afterwards that she’s not getting one this year.

VikaOlson · 20/10/2025 15:36

Mine never have over 10+ years of getting it.

SquigglePigs · 20/10/2025 15:31

DD (6) was a little tired and snuffly for a day or so but otherwise no noticeable side effects.

Mine get all their vaccinations. They continue to get their flu vaccinations every year, despite having side effects every year, because the side effects aren’t as bad as flu would be. I don’t think it’s helpful to pretend that there are never any side effects from the nasal flu vaccine, they are well documented due to it being a live vaccine. Just because my kids have always reacted and I’ve answered the question honestly, it doesn’t mean I’m an anti vaxxer.

Unfortunately among the genuine posters there are many people posting on here to make vaccines look untrustworthy who do not appear to be genuine and it’s a huge public health risk for everyone but particularly the old and the very young.

If they had their vaccinations 5/6 days ago I'd say it's more likely a bug. Especially if you've come down with it too.

Mine had a bit of a fever the night of the vaccination last year, but previously nothing and it might have been a coincidence - the autumn term is a bug-fest, after all.

Illness started 2 days after their vaccines respectively

It’s totally fine, I was just wanting to know if it’s a common thing or not.

it could be a bug. But it’s every year so seems unlikely to be a coincidence

Nope, but all of Y3 got taken out with a vomiting bug last week. And by all, I mean all but 2 of them, they were dropping like flies that’s how fast it moved through the class in a matter of hours. They haven’t had their flu spray yet. It’s just going around.

Dd had hers and now has a cold and cough. It’s not from the spray though, because Dh who is always sick had it first.

I’m immunocompromised due to cancer treatment, and I got neither the cough/cold nor the vomiting bug, so go figure. I also didn’t get COVID when dd had it a few weeks back. 🤷🏻‍♀️ There is just a lot of sickness right now, but I don’t think it’s from the flu spray.

No, never. My son almost died from influenza A aged 5 so I’d accept a very high level of side-effects let alone a bit of diarrhoea, though.
