To not want baby near unvaccinated toddler?

[victoriaspomge]

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?

Sorry to hear that. 2 doses are 95% effective against measles, however no vaccine is 100%

It's actually 97% for two doses and 93% for a single one. Some publications combine the two figures and say 95% without differentiating.

For measles, the herd immunity threshold is 95% vaccination rate, which results in people unvaccinated - for whatever reason, simply not being exposed to the virus. Tragically, because of disinformation, which is believed by people, we're significantly below that currently.

"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"

So these are within the incubation period of mumps and measles and are definitely not mumps and measles, just similar.
Handy to know.

It's interesting what a PP mentioned about measles infection causing low immune function for a few years afterwards which can leave people susceptible to other illnesses. I've just realised why myself, my DSIS and DB contracted other illnesses the following year - other than them maybe being prevalent at the time. According to my DM's records we all had measles in 1965, then whooping cough (even though vaccinated for it) and glandular fever in 1966. This was before the vaccines were available. I remember her saying how run arse ragged she was looking after us, to the point she had to stop breastfeeding our youngest DB, and how some of her friend's children didn't survive.

Have I vaccinated my DC? Although I was ok, and have lifelong immunity to measles, you bet I have.

Ask your partner which is more important to him. The safety of his child or the feelings of the adults involved.

If a child is unvaccinated then they would b sick with said things like measles there’s more chance of a vaccinated child carrying the disease whilst not being effected because they’re vaccinated so u wouldn’t b better not letting anyone near ur baby until they’re vaccinated

This is not correct.

There is still an intubation period with unvaccinated children and it is likely to be at least 4 days before symptoms show.

Vaccinated children are much less likely to catch measles and therefore to pass it on. If they do catch it it may be milder but is unlikely to be completely asymptomatic.

Do we not all make an effort to avoid catching our eyes on hooks, though? Would it not make similar sense to try and avoid infectious diseases? 🙄

Well they could have vaccinated you?

Er, actually sometimes they are. A child with measles/whooping cough etc., either in the incubation period or with the active virus, is quite literally a posionous monster around an unvaccinated baby. Just because you can't see the virus doesn't mean they don't have it.

I was vaccinated

That's interesting. I had whooping cough within a year after having measles but it's never occurred to me that there could be a link. It wasn't a fun time.

As i said above, i was really ill year following measles with chronic tondillitis. My sister and i werent allowed to have measles vaccine when it was introduced because my sister was still having febrile convulsions ( abnormal genetic fc now known as GEFS+)

Are you asking for all the vaccination records of every adult who visits you too? Literally anyone could be incubating anything at anytime.

Get your kids vaccinated and get a grip!

Ops baby is too young to be vaccinated

Anyone who hasn't received a whooping cough vaccine in the last 5 years is a potential whooping cough spreader. Whooping cough has around a 3 week window where it is contagious vs 8 days with measles and for some of that 8 days a rash will be present.
This will mean most adults are a whooping cough risk, as only pregnant women tend to be offered boosters as adults.

So if the jab lasts 5 years then every 6 year old onwards doesn't have the protection?

Errrr you can also still get measles and whooping cough after having the vaccine as others in this thread have said and also I know this from experience so it makes no difference at all. You could get his by a comet too .. but we all live our lives!

Everyone will be different but it seems that immunity induced by that particular vaccine wanes quite quickly over time. Immunity from contracting the virus seems to last longer according to the literature but isn't lifelong. (7-20 years vs 5-10 years according to one study I found).
It's likely to be much more prevalent than we know and particularly under diagnosed in adults as we tend not to get the characteristic "whoop".

I'm curious about measles vaccine immunity now and whether adults should be considering boosters.

"Among people infected with measles in England between 2010 and 2019, the proportion of cases who had previously received two doses of vaccine has increased, especially among young adults. Possible explanations include rare infections in vaccinated individuals who did not gain immunity upon vaccination, made more common because fewer individuals in the population were born in the endemic era, before vaccination was introduced, and exposed as part of endemic transmission, or the waning of vaccine-induced immunity, which would present new challenges for measles control in near-elimination settings. We aimed to evaluate whether measles dynamics observed in England between 2010 and 2019 were in line with a waning of vaccine-induced immunity."

I'm not fluent in emoji, would you mind explaining? You don't have kids but your oldest got it? Makes no sense

It does make a difference getting vaccinated against measles in that that the vast majority of people who've had it will have immunity.
Given that vaccine hesitancy and misinformation is becoming more and more a challenge I remember reading that it was one of the top 10 threats to Global Health a few years ago) we all decide on the level of risk we take in anything we do, and anything that in this case a mother might not want to potentially expose her baby to.

Of course not. There is a difference between taking a chance in the wider world (in which the majority of people are vaccinated) and knowingly exposing yourself to the risk of an unvaccinated child, who could be carrying potentially deadly virus without presenting with symptoms. If you can't differentiate between those two levels of risk, I doubt anything anyone says here will help you.

You can indeed still get those illnesses but it is very, very rare. Far rarer than a vaccinated child/adult getting them.

Or let's put it another way. I assume you use a seatbelt/child seat when driving a car. Presumably you don't usually expect to get in an accident - so do you use them anyway because we manage the risks we can or you don't use them because you think they're unlikely to be needed as you probably won't have an accident?

Risk is inherent in everything we do, it's a part of everyday life. Vaccination, just like seatbelts and child seats is all about managing those risks.

1-3% is not very very rare. 0.006 of something like that would be very very rare

It's still far, far rarer than unvaccinated children getting measles! Well over 90% of measles cases today are in unvaccinated children. I think I'll take those odds.
