Five cohort studies involving 1,256,407 children and five case-control studies involving 9920 children were included in this analysis. • There was no relationship between vaccination and autism (OR: 0.99; 95% CI: 0.92 to 1.06). • There was no relationship between vaccination and ASD (OR: 0.91; 95% CI: 0.68 to 1.20). • There was no relationship between vaccination and MMR (OR: 0.84; 95% CI: 0.70 to 1.01). • There was no relationship between vaccination and thimerosal (OR: 1.00; 95% CI: 0.77 to 1.31). • There was no relationship between vaccination and mercury (Hg) (OR: 1.00; 95% CI: 0.93 to 1.07). • Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder.

There has been enormous debate regarding the possibility of a link between childhood vaccinations and the subsequent development of autism. This has in recent times become a major public health issue with vaccine preventable diseases increasing in the community due to the fear of a ‘link’ between vaccinations and autism. We performed a meta-analysis to summarise available evidence from case-control and cohort studies on this topic (MEDLINE, PubMed, EMBASE, Google Scholar up to April, 2014). Eligible studies assessed the relationship between vaccine administration and the subsequent development of autism or autism spectrum disorders (ASD). Two reviewers extracted data on study characteristics, methods, and outcomes. Disagreement was resolved by consensus with another author. Five cohort studies involving 1,256,407 children, and five case-control studies involving 9920 children were included in this analysis. The cohort data revealed no relationship between vaccination and autism (OR: 0.99; 95% CI: 0.92 to 1.06) or ASD (OR: 0.91; 95% CI: 0.68 to 1.20), or MMR (OR: 0.84; 95% CI: 0.70 to 1.01), or thimerosal (OR: 1.00; 95% CI: 0.77 to 1.31), or mercury (Hg) (OR: 1.00; 95% CI: 0.93 to 1.07). Similarly the case-control data found no evidence for increased risk of developing autism or ASD following MMR, Hg, or thimerosal exposure when grouped by condition (OR: 0.90, 95% CI: 0.83 to 0.98; p = 0.02) or grouped by exposure type (OR: 0.85, 95% CI: 0.76 to 0.95; p = 0.01). Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder. Furthermore, the components of the vaccines (thimerosal or mercury) or multiple vaccines (MMR) are not associated with the development of autism or autism spectrum disorder.

When the autism thing broke in the UK vaccination numbers dropped dramatically for a time.
A simple study could resolve the thing easily.
Eg Vaccination down 50% for the year, autism numbers for that year is?

That would be a correlation study, not quite as useful.

There is NO WAY I will let my kids be vaccinated unless I have seen a full toxicology report on ALL the ingredients that they are to be injected with. I also want a written guarantee that no long term ill health will befall my children after said vaccination. In an era of skyrocketing incidence in autism, ADHD, Asperger’s allergies, and all kinds of children’s health issues how do we know that it is not the insult of vaccination to underdeveloped immune systems triggering these disorders? We don’t. Hell let’s just spin the wheel if you’re child is an unlucky one you can just take one for the team? I think not. Disease creation and making billions is the game played by big pharma, and you are all suckers. I have no objection to the principle behind vaccination, but by all hell I have a massive problem with the stuff you are using. You stay well away from my children.

I’m a bit like you. I won’t drive over a bridge unless I have a full structural report including the tensile strength and load-bearing capacity of EVERY piece of metal used in its construction. Actually, I object to the use of metal – the same stuff atom bombs are made from. Some bridges are even made out of wood, the same stuff paper is made from. Yes, that’s right – many bridges are made out of paper. Engineering companies earn billions from bridge-building but, not surprisingly, bridges collapse all the time so they get to build more bridges and make even more money. People die when bridges collapse – are you willing to spin that wheel and hope you aren’t among the dead? I have no objection to the principle behind bridges but they need to build them properly and make them safe. Metal and wood are simply not good enough. Until then, there is NO WAY I will ever cross a bridge. I swim across rivers instead, the way nature intended – it’s far safer. No one ever died when a river collapsed.

Progress, I like that.

Not ‘refrigerator mother’, not vaccines.

Now, does the study eliminate the possibility that the immunizations/vaccines given to the mothers (or fathers) aren’t somehow a contributing factor?

Of course I’m shit stirring, never knock back an opportunity to encourage a scourge of contagious paranoia.

I have a theory, that vaccines contribute/d to keeping alive many that would have died, of many that would have died that didn’t and went on the replicate there is a broader spread/ing of biological expression, amongst this spread are certain neurological diversifications which haven’t or aren’t being selected out of existence.

On this basis I say ummunizations are contributing to the incidence rate of what is commonly denoted autism/spectrum disorders.

So, immunizations don’t directly cause autism in the organism that has them, no.

Further, I would add that no studies have ruled out the possibility of a more direct link between vaccines and autism via parents to offspring.

Probably there is a link between vaccines and autism, but it’s not as direct as people might to be inclined to consider it, and the truth is probably a thousand times more ghastly than the more direct causal proposition being entertained.

Please show working.

Well we could jointly sketch out some things we agree on and go from there.

Do you agree immunizations have kept alive many people that otherwise would have died.

But it could be anything, even the contarceptive pill women take may influence their sense of smell and mate choice.

Lets put immunisation to one side for the moment and deal with the real threat to our long-term well-being:

Clean water and piped sewage.

Yeah you have to keep the clean water out of the piped sewage.

Parents never like to think that it was ‘something they did’ or an environmental factor they created that caused autism.
The while anti vaccination movement is based on, now debunked, ‘research’ by a, now admitted, ‘bogas doctor ‘.

But what if it is just there? Just something that happens… Like twins that don’t quite divide in utero? Or limbs that don’t quite form? Through no fault of the mother father or genetics… It is just the way it is.

>Clean water and piped sewage.

I would in and OP related to that subject.

The biggest link between vaccination and autism is the similarity in the age of general presentation of disorders like autism and the current vaccination schedule.
