Because even things that are toxic can have beneficial effects if they are administered appropriately.

This is a recycled story from over 2 years ago.

"In June 2012, a local court in Rimini, Italy, ruled that the MMR vaccination had caused autism in a 15-month-old boy. The court relied heavily on the discredited Lancet paper and largely ignored the scientific evidence presented to it. The decision is under appeal"

"The MMR vaccine controversy centers on the 1998 publication of a fraudulent research paper in the medical journal The Lancet that lent support to the later discredited claim that colitis and autism spectrum disorders are linked to the combined measles, mumps and rubella (MMR) vaccine.[1] The media have been criticized for their naïve reporting and for lending undue credibility to the architect of the fraud, Andrew Wakefield.

Investigations by Sunday Times journalist Brian Deer reported that Andrew Wakefield, the author of the original research paper, had multiple undeclared conflicts of interest,[2][3] had manipulated evidence,[4] and had broken other ethical codes. The Lancet paper was partially retracted in 2004, and fully retracted in 2010, when The Lancet's editor-in-chief Richard Horton described it as "utterly false" and said that the journal had been "deceived."[5] Wakefield was found guilty by the General Medical Council of serious professional misconduct in May 2010 and was struck off the Medical Register, meaning he could no longer practice as a doctor in the UK.[6] In 2011, Deer provided further information on Wakefield's improper research practices to the British medical journal, BMJ, which in a signed editorial described the original paper as fraudulent.[7][8] The scientific consensus is that no evidence links the MMR vaccine to the development of autism, and that this vaccine's benefits greatly outweigh its risks."

To those sighting anecdotal experience, I can to. My brother is autistic and never had a vaccination of any kind. I never had a vaccine either and got, measles, mumps, rubella, and chicken pox but had to get admitted to an ICU due to complications (encephalitis) of chicken pox. Good thing I avoided those nasty vaccines though.

In all seriousness though, PDD, ASD, GDD or any other acronym you feel like throwing around represent a range of disorders that due to their very nature are not apparent from birth and only start to manifest months to years later which spans the same period of time when childhood vaccination usually takes place. I'm not saying that vaccinations are perfect or never have adverse effects but utilising anecdotal reports and fear-mongering to discourage people from vaccinating their kids DIRECTLY causes harm.

Vaccination has been so effective for so long that people forget that these diseases used to kill many, many children. For a final anecdote, 4 of my mother's siblings died from vaccine preventable illnesses.

Some people cannot be vaccinated for medical reasons, such as those with severely compromised immune systems or certain pre-existing medical conditions. These people rely on everyone around them being vaccinated to keep them safe. Also, like any medicine, vaccines do not succeed 100% of the time; generally, over 90% of people vaccinated gain lasting immunity, but a small minority don't, and they also need to be protected by the people around them.

There's a concept called herd immunity; basically, if you immunise a large enough portion of a population, a disease can't spread within it. Once you drop below that number, however, the disease begins to spread again. With Diptheria, for example, 85% of people must be immune for it to be held in check. With Whooping Cough, the number is 92-94%.

Measles has made comebacks in many industrialized nations because after the MMR hoax, a lot of people didn't vaccinate their kids, the percentage of the population with immunity fell, and the disease became endemic again.

well maybe somthing musst change, vaccinations are important, but why giving 6 at once? there is enough time for vaccination and it doesnt hurt. its not unsafe to vaccinate atm, but it could be safer, if they just get vaccinated against 2 illnesses at a time. not vaccinating isnt a option, all the illnesses are much worse than the possible siteeffects from vaccinating.

i dont think they should make it mandatory, but they should ban unvaccinated kids from kindergardens, school, etc. because its a safety concern if some people arent vaccinated in a class.

Vaccine is not harmful nor does it cause autism. Autism is neurological and you are thus either born WITH it or NOT, it's nothing you simply "pick up" along the way. I know that because I've worked with people with autism/aspberger. Do not spread around stupid ideas about vaccine padib!

It depends on the vaccine, but basically, your child is one of the incredibly unlucky ones to have had such a severe reaction. Thousands of kids get vaccinated with no side effects.

Having said that, PDD-NOS is notoriously difficult to actually diagnose. From what I remember, the diagnosis guidelines say more about what a child isn't than actually specifying any actual symptoms. PDD-NOS is basically diagnosed when the physician isn't actually sure what's wrong, but some symptoms normally associated with more severe conditions are present. My nephew also suffers from PDD-NOS, but from what I remember, the diagnosis actually differed from country to country (he wasn't living in the UK when he was diagnosed).

As somebody with autism, I second this. ;)

The burder of proof is on those claiming there is a link. In this regard, it's up to those claiming vaccines are linked to PDD to prove there is a link. A chronological link alone is not enough to prove there is a link seeing as how chronological links are ubiquitous.

Fortunately, there is - and many have provided this proof already in this thread

I particularly suggest you watch this youtube clip:

Can every body in this thread please keep cool heads and be polite to each other.

And anti-vaxxers, I have no intention of banning people because they agree with the overwhelming and crushing weight of science. So unless they are actually flaming or trolling in some way, please stop reporting them.
