A wee linky or two
Here's a link to the original Wakefield paper which started the whole MMR and autism scare.
http://www.freenetpages.co.uk/.../Wakefield%20Feb%201998.pdf
Any practicing scientists out there will, I'm sure, be as horrified as I was that the Lancet published this. The work is of exceptionally poor quality and the Lancet has, in fact, apologised for publishing it in the first place.
To get an overview of the entire fiasco see here
Andrew Wakefield: a cheat exposed
No one has ever denied that vaccines can have side effects, in fact vaccination is intended to give you a mild form of the disease in order to "show" your immune system what the invader looks like. Next time round the immune system can zap it before it can get a grip on you (this applies to live, attenuated vaccines).
What is not in question is that the side effects of any given vaccine have to be milder than the disease itself. So for typhoid it's acceptable to feel pretty rough for a few days, not so for flu vaccination.
Although rubella is a mild disease in itself, we all know what it does in the first trimester of pregnancy. It isn't true that vaccinated children lose their immunity by the time they're adults. In the UK pregnant women are screened for rubella immunity at the start of their pregnancy. The vast majority are immune. The whole point of vaccinating children is to raise the herd immunityto the disease. This means that an unvaccinated pregnant woman has less chance of coming into contact with the disease.
The same herd immunity is used when vaccinating for whooping cough, measles diphtheria etc. There are some children with malfunctioning immune systems and also ALL newborns who cannot be immunised and can't risk being exposed to these diseases since they would probably be killed by them.
I'm all for vaccination if it helps to protect the most vulnerable in the community from dying of some of these diseases and it prevents my child from the horrible effects of whooping cough, diphtheria, tetanus, polio, measles, mumps etc. The risks from vaccination are very low, the risks from the diseases is very high.

Original post
I've posted my initial post to LindLou here
Re: Vaccinations
I know Amin PD has asked us to take vaccine discussion to the appropriate thread, but I feel that this is relevant. You say
but at least I am informed about vaccinations now and can make good decisions for us both in the future.
Can I use a single example from your post to show that you are not quite as informed as you believe. If you go to the following site
Vaccine-Preventable Diseases - Diphtheria
you will notice that the tell you diphtheria vaccine is actually an inactivated form of the diphtheria toxin. This causes you to produce antibodies to the toxin and not the bacterium. Naturally occurring, non-toxigenic diphtheroids, by definition do not produce toxin. Therefore I find it hard to see how these bacteria will confer resistance to diphtheria toxin.
The problem with diphtheria is that the toxin it produces (an iron-chelating siderophore) is only produced when iron availability is low and it inhibits protein synthesis all round the body, producing pathological effects in the heart, kidney, gut etc. By targetting the toxin the vaccine ensures maximal protection from these effects. The genes for toxin production are carried on a bacteriophage which the toxigenic strains carry. There are non-toxigenic strains of Corynebacterium diphtheriae. these confer no resistance to the disease whatsoever.
I'm not trying to have a go at you, just to demonstrate that you can make yourself even better informed and make the right decisions for the right reasons.
I've only used a small part of your post as an example. If you would like to discuss this further, I'll meet you in the vaccine thread.

Re: Relevant Recent News about Vaccination Policies
I couldn't let this pass. You said
I agree that there is no evidence that says for certain that vaccination and autism are causally linked. However, it is a fact that autism is much more common than it used to be, and also that children are receiving many more vaccinations than they did in the past. I accept that it is a fallacy to assume that because A and B happened at the same time, they must be connected. But I think it ought to at least prompt some questions. Autism isn't the only disease/condition in children that is on the rise.
Do you also agree that many more children are keeping hampsters as pets as the rate of autism has increased? Should this prompt some questions?
This is exactly what Andrew Wakefield did in his study which claimed that the MMR caused autism. He studied a grand total of 12 children who were selected on the basis of having autism, what he called "autistic bowel disorder" or both and then asked the question "How many of these children were given the MMR?"
Given that the MMR uptake rate was pretty high at the time, the answer was pretty high, 11 out of the 12 I think. On the basis of this AND THIS ALONE, he announced that MMR caused autism and vaccination rates still have not recovered.
All his co-authors on the paper have retracted their claims, subsequent studies have totally refuted his claims, the journal which published the original paper did so only to show how NOT to do research and explained this in their editorial of that issue. Unfortunately that wasn't reported. The media missed the point completely and the journal has said they should never have published in the first place.
Meanwhile, there are still poeple who use outdated source material and claim to be informed. You can't use source material from the nineties and expect to be up to date or well-informed, I also note that many of your antivaccination sources are from the 1960s and before. Thy're worse than useless - they're dangerous and to trust you child's health to outdated opinions WHICH HAVE SUBSEQUENTLY BEEN SHOWN TO BE WRONG is misguided at best.
A suggestion for you is to look at all the evidence. Don't just look at the evidence which you think supports your point of view. The reasons all the sources you have given are so old is because those sources which refute you are the more recent ones and they are pro-vaccine. Any anti-vaccine evidence of more recent date can only be found at crank websites, expounded by people who don't understand what they're talking about, but who know a few buzzwords which impress the even worse informed.
I'll try to dig out more info on the Andrew Wakefield paper. I have it on .pdf on the hard drive of a dead computer and don't think I can access it. Can I say that after having read his paper I was appalled at the total lack of thinking, critical or otherwise, which went into that paper. I'm a research scientist myself. If I produced research of that quality, I would fully expect and deserve to be fired and blackballed.
