To not want baby near unvaccinated toddler?

So basically my partner wants his half brother's (same dad) younger half brother (same mum) to come and meet our baby.
He has a daughter who is 2 years old who he says is our kids cousin.

My partner is no relation to him or his daughter biologically but because they share a half brother he feels as if it's his brother as well and that they are family.

He dosent really know him and doesn't have his number and has only met him in the last 10 years.

They only hang out if it's with their mutual half brother.

I know the 'brother' is very anti vax and has not got his 2 year old vaccinated despite living in a city where it has had a lot of cases of measles.

Baby is too young to be have the MMR and I am extremely worried about my baby meeting this 2 year old.

AIBU to feel like this?

I can reply the same way , my son had all his vaccines until the mmr where he was brain damaged for life . Consequently none of his siblings had it . None had measles , my son had measles himself 2 years after . Attacking others by calling them Google readers is offensive when i live daily with the consequences of vaccines and see people on this thread calling names to people who don’t vaccine without even trying to understand the reasons . So with all due respect I maintain what I say when I say no child vaccinated or not can pass on what they don’t have . I suggest OP maintain her child at home away from baby groups , swimming , and any other baby activities because nobody is obligated to disclose what their decision about vaccines is .

made up numbers but the idea is right - ii may have understated the benefit of the vaccine

if we had 10000 children who got vaccinated we may get 1 who suffered a reaction to the vaccine

if we have 10000 children unvaccinated we may have 5 dead and 50 harmed for life

i know which group I would like my children to be in

there is no conspiracy and death rates are available for analysis

My children are much older now but when they were babies I wouldn't have had a clue about the vaccination status of all the other children they met. Is it a new thing to be asking this? I'm really surprised you would know this about multiple children.

Are you in the UK? It wasn't even something that was asked about at nursery as I remember a conversation with an Australian friend who was surprised by that

It's because herd immunity protected people and children as it kept up the 95% rate due to people getting their children vaccinated. Measles is a horrific, horrific disease which was pretty much eradicated in the UK, up until that evil man (who I can't even bring myself to name) doctored a research paper that claimed the MMR caused autism. Total and utter piffle. He's been stuck off now thankfully, but the damage he has done with this and I do hold him responsible for the deaths of vulnerable people and children from measles since.

Idiotic people still believe the nonsense so unfortunately the UK has now slipped down the list of safe countries without measles due to absolute idiots like this half brothers half brother who won't vaccinate their child. The levels of herd immunity need to stay above 95% as it protects those who cannot get vaccinated due to immune issues etc.

What we are seeing now is the cause and effect of this dip.

I don't disagree with you on that (I'm since vaccinated and so are my kids). Luckily as a child no one avoided me because of my vaccination status but I guess that's the 80s for you where people didn't have social media to get themselves all worked up over. I feel sorry for the kids who aren't vaccinated, firstly because of the risks to their health and secondly because they are branded as a risk and to keep away from.

Having looked as statistics, there have been 957 confirmed measles cases in the last year. That's barely anything compared to the population of the UK.

That equates to about 100 with compromised immune systems, which take years to recover properly. It makes simple illnesses far more serious.

About 200 will require hospitalisation, with about 50 of them developing pneumonia. One of them will have had potentially fatal encephalitis. Between 10 & 30 of the entire cohort will die as a direct result of catching measles.

One in 9 will develop nerve damage, with the commonest result being visual and hearing problems - they will never recover from this.

But as described by a PP below, lots of children and adults are also damaged from having the vaccine itself. They won't generally appear in the figures because the pharmaceutical companies make themselves untouchable and their disclaimers are vast and thorough.

To each their own.

Ultimately it sounds like the OP has already made her mind up and just wants some cheer leaders.

Every part of parenting, and daily life itself, has risks. Basically: make an educated choice and be lucky.

Good luck OP and I genuinely hope you have a lovely time with your baby and wish them good health, they really do grow quickly so enjoy making memories :)) x

Yep. It doesn't feel like barely anything though if you or your child are one of the 957 and who either died or suffered lifelong damage from it.

TaraC25 · 09/02/2026 22:59

IMO You're being ridiculous.

If you're confident that vaccines work to protect your baby, then surely your baby wouldn't catch anything anyway? Being vaccinated doesn't stop people (or babies/toddlers/children) from spreading and passing viruses.

The toddler could still be breastfed for all you know and have amazing natural immunity!

Well breastfeeding doesn't protect against measles 😅
And measles is a big risk so if people choose not to vaccinate then they really do choose to become social pariahs 🤷🏻‍♀️

This. Everything we do carries a certian amount of risk. Isn't it normal to go with the lowest risk factors? Especially when trying to protect your children?

I’m not going to comment on the family dynamics but there’s no way in hell when mine were babies would they be near unvaccinated children until mine had the vaccines. This is a hill I would happily die on.

Does that mean your baby doesn't see any other babies until they are 13 months plus and had the MMR?

JerryTubs · 10/02/2026 09:45

I would just say ‘not until my baby is vaccinated as I’m aware yours isn’t.’ It’s about time these non vaxxers realised their actions have consequences. They’ve been relying on us vaccinating our children so that theirs remain safe and it’s so unfair! We have to take the risks and listen to all these people tell us the risks and we do it anyway, wondering if we’ve made the right choice, feeling guilty, people telling us our kids might be autistic because we vaccinated etc. I feel quite strongly about this. Tell them straight.

Well no, but you also can't eradicate all risk.
There is risk to taking medication, I've seen some horrendous reactions to prescribed medications, it doesn't mean it shouldn't be taken by anyone ever... It means you have to make a choice and be fairly confident in that.

It is entirely natural to suffer 'survivors guilt' and what ifs when things don't go as expected.

As a new mum, OP is going to face a lot of judged decisions over the coming years, my best advice is grow a thick skin..!

mathanxiety · 10/02/2026 04:26

The OP's baby is still too young to be vaccinated.

The 2yo has not been vaccinated.

The 2 yo has likely been out and about, possibly even to nursery, and could be carrying the virus.

Breastfeeding is not a substitute for vaccination.

The OP's baby is vulnerable.

Go and educate yourself wrt vaccination and contagion.

Most babies are in childcare before getting the MMR though. And no one gets neurotic about that

https://cks.nice.org.uk/topics/measles/background-information/complications/

  • Complications of measles occur in 10–20% of people in developed countries, but the number may be much higher in developing countries.
  • Blindness can result from measles keratoconjunctivitis or other ocular complications, and occurs mainly in children with vitamin A deficiency. Measles is a leading cause of childhood blindness globally.

https://www.cdc.gov/measles/signs-symptoms/index.html

Side effects of the MMR vaccine
Like all medicines, the MMR vaccine can cause side effects, but not everyone will get them.
Common side effects are usually mild and only last 2 to 3 days, they include:

  • a raised, blotchy rash (similar to a measles rash), feeling unwell and a high temperature around 7 to 11 days after the vaccination
  • swollen glands around the cheeks, neck and jaw and aching in your joints (similar to a mild form of mumps) around 2 to 3 weeks after the vaccination
More serious side effects, such as a severe allergic reaction (anaphylaxis) are rare. The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.

"We have to take the risks"... Nice bit of virtue signalling there. You don't HAVE to. You chose to. Everything is a choice.

Oh kindly fuck off. If we didn’t make those choices all the kids would be fucking dying of diseases we had almost eradicated. I don’t care if it’s virtue signalling, non vaxxers are fucking morons who have taken advantage of our choice to do the right thing for too long.

It’s different when you know someone definitely isn’t vaccinated though I should think. You don’t usually know these things so therefore you aren’t faced with the choice.

How selfless of you.

Don't tell me.. You've had six covid boosters and are still terrified to go near anyone with a snotty nose...?

Nice assumption.

You will find that many highly intelligent and educated people don't get vaccines.
Look up Dr Steven James who gave his thoughts on the covid Vax, he is an ITU Doctor.

It's offensive to resort to insults and name-calling.

BoredZelda · 10/02/2026 10:25

TaraC25 · 09/02/2026 23:09

So is OP intending to avoid all other babies and toddlers then?

Because this toddler certainly won't be the only unvaccinated child they come into contact with. And I'd say as long as the toddler isn't kissing the baby all over the mouth, it's not a risk to it anymore than any other relatives are?

You say this like it’s impossible. My daughter wasn’t around any other babies or toddlers before she was vaccinated. We don’t have any in our family and there was never a situation where it would happen.

There is no world where I would have introduced an unvaccinated toddler into our home before she was vaccinated.

Okay.
So if you go on to have another baby, are you going to stay indoors for the first 13 months? Because you surely will be supervising your older child to socialise; soft play, swimming, play dates etc and they will absolutely breathe the same air as others..!

Ultimately OP has the choice to stay in a sterile bubble for a long as she wishes, or as long as her circumstances allow and that is her right.

The fact you think it's one doctor shows how uneducated you are on facts.
During the pandemic, approximately 100,000 NHS and social care staff were going to be sacked for not agreeing to have the covid vaccine trial. So it wasn't just one doctor, far from it.

This is entirely irrelevant to OPs situation other than pointing out that there are many people that make decisions different to our own; that doesn't make them selfish, stupid or careless. It makes them human. EVERY single one of us has autonomy over our own body and what we choose to put into it: if the OP doesn't want her child around an unvaccinated child that's her right... I still personally think it's a bit ridiculous, but that's the thing with opinions - they're like arseholes - we all have one and I'm absolutely fine with people disagreeing with me on that.

Im confident in the choices I made for my own babies and I respect people's right to make their choices too, even if they differ from my own.

Edited

Dr Steven James who had an issue with mass vaccination for NHS staff but said he was pro-vaccine for the groups who were at risk? Who chose not to have the vaccine for himself for his own reasons, but never said nobody should get it? Who has never spoken out against any other vaccine?

The “ICU doctor” who is largely now just touting his Weightloss programmes and £500 a session breathing classes?

He’s the guy you are basing your entire anti-vax stance on?
