This really needed a re-write. As always, no double glazing salesmen, please.

What do you mean no double glazing salesman.

Hello Alex

I'd suggest:
In the year before MMR vaccination was introduced, the mumps virus produced around a thousand hospitalisations, and five of those patients died.

fifteen = 15

There's a missing element in that sentence.

and there *may* be an increased risk of the child missing one or more of the vaccinations.
Good update, thanks Alex

Yes, important update this one - well done Alex
immunosupressant >> immunosuppressant
Also, would it be worth pointing out in the herd immunity discussion, that a virus can only survive if it can find new hosts to infect. If the average number of new people infected by each infected person is less than 1, the disease will die out naturally.

"No double glazing salesmen" = no long, arduous rants about a certain point of view, such as those you might encounter when you have a double glazing salesman with his foot in your door.
GB, I've made all those changes () except for the first one ("However, use lower case when talking about entries in general." - <./>EditedGuide-Style</.> and the last one ("there would be an increased risk of the child missing one or more of the vaccinations" - the word 'risk' already implies a 'may or may not', and besides it's a recognised fact)
I've added a footnote about viruses dying out

I've added a section on Clinical Reasons Not to Vaccinate

Hi Alex - nice job
This statement leapt out at me a bit:
"Scientifically sound studies consist of thousands of subjects"
That is certainly true for *epidemiological* studies, but not for all scientific studies! A well-designed clinical trial in patients with a very rare disease might be scientifically sound with only 40 or 50 patients. I'd suggest clarifying that a little.
And a minor point: I was always taught (as a medical writer by trade) not to use the word 'subjects', but use patients, individuals, participants or something similar. It just reminds the reader that these are human beings we're talking about, not animals or inanimate objects!

Nice, well-balanced Entry, Alex (I'd had it in mind to do this Updater myself at some point)
A couple of things:
I think it would be worth emphasising that 'Like ALL vaccines, the MMR vaccine can cause side-effects... (i.e. the soreness, redness, swelling etc. at the site of injection. These are caused by an immune response against vaccine components e.g. ovalbumen in virus vaccines that have been produced in eggs..
Mention that thimerosal contains mercury, and I'm sure there's a LINK you could make here.
I don't think you emphasise sufficiently the dangers of measles virus infection.In the developing world, mortality from measles in malnourished infants is one of the leading causes of death. If I recall, measles virus is THE leading cause of blindness in such children. Thus children lose appetite and this particularly affects vitamin A intake (LINK) leading to blindness. If I recall, 100,000 cases of blindness per year in the world are attributable to infection by measles (However, I've mislaid my textbook of medical virology since tidying my office.
Measles virus is also associated with various diseases of unknown aetiology. Many of these are 'autoimmune'. Conditions which have been linked with measles virus infection include MS, Crohn's Disease, Kawasaki and Paget's Diseases (When I was working at &*$£% colleagues in my department were collaborating with Wakefield's group using labelled antibody techniques to see if they could detect measles virus antigens in bowel tissue from patients with Crohn's. I left before this work was completed so I don't know the outcomes.)
I may come back to this next week. I have to off to attend a wedding this weekend.

Ref encephalitis, there are three forms of virus encephalitis.
The figures I have to hand (1993) are:
*Acute postinfectious measlres enceph. (1 in 1000 cases)
* Measles inclusion body enceph.. Usually occurs in immune-suppressed individuals.
*SSPE. 1 in 25000. i.e. Rare but fatal.

I've included most of that, except for the encephalitis figures (they change all the time and don't mean all that much to the lay person).

Fantastic Entry!
My only query is over the last sentence - given what you've said about herd immunity earlier.

'thimersal, a mercury-containing vaccine component...' > thimerOsal, a merccury-containing vaccine PRESERVATIVE...'
I still don't think you emphasise enough the dangers of natural measles infection. Thus in the 3rd World it is a massive killer - for reasons as yet unknown. This is what an article from NIMR Mill Hill says (I'll put the link in the following post):
'If there were no vaccination every child in the country would get infected with measles giving an average of about six hundred thousand cases per year. It is estimated that between fifty and one hundred would die as a result either of infection of the brain, (encephalitis) or from pneumonia. Up to ten years later a few more would die of the effects of measles virus lingering in the brain rather than being cleared from the body by the immune system as in most cases. Delayed death is due to the invariably fatal disease called sub acute sclerosing pan encephalitis, or SSPE for short. In developing countries, in contrast, measles is a massive killer, for reasons that are still not entirely clear'.

Yep, that's
... but thiomerosal >thimerosal (unless your way is an accepted alternative. I only know the latter)
