That is called scientific theory. Vaccination is trying to replicate the natural process in which the body builds an immunity to viruses i.e. by recognizing the virus, and creating antibodies (However antibodies is just one way the body fights viruses.). Whether vaccination does actually successfully replicate this immunity passed on through the natural process in reality needs to be studied.
A randomized double blind study is required to test this theory. Many times theory does not correspond to real life when put to the test. Can you show a randomized double blind study on measles (as well as mumps and rubella) and mmr? I want to see the data and results for it. Not some relative %, or a review of the study by somebody else. You'll be surprised that when you do look into a positive review of a study, and find that the data does not match or are blown out of proportion. All I see in those two links are the typical rhetoric including the ad hominem of those who decide not to vaccinate.
The burden of proof is on the vaccination promoters (e.g. the pharmaceutical) to prove to the 'asshole' parents that mmr does work against measles, mumps and rubella.
I suppose my question would be, at what point do you accept what you read, or, at what point do you trust something?
For example, here is one source that says that two doses of MMR provides near 100% protection from measles:
HPA - Study confirms measles component of MMR vaccine is highly effective
And here's one about trials in about 15,000,000 kids on MMR:

I didn't look much but there are some quick examples, though not perfect obviously.
So do we now get to the point where we say, yes but those are obviously fake and the gover-pharma-corp-9/11-masters are just duping the population with fake studies?
So would we have to do our own studies personally with people we are certain are 'random' etc to be satisfied? At what point do we trust this stuff.
And I refer to my earlier post on page one about polio etc. I mean seriously, if you don't vaccinate against stuff like that you are one small part of its resurgence. How do you think polio has been almost wiped out?
Does anyone against vaccines here actually understand how much it's taken, how much creativity and ingenuity and hard work it's taken, to make them work? And how complicated the process has been - even just for a single one like polio?
There are people who have put their lives into the study of vaccines, some of them for no pharma profit like you think (Salk with polio) and in the sweep of a few posts there is somehow "burden of proof" back on them, even after thanks to them we've gone from hundreds of thousands of people dying to pretty much wiping out these diseases. What more proof do you need.
What more proof do you need for the burden of proof to be satisfied, that polio vaccination is a good idea:
"Poliomyelitis has appeared in epidemic form, become endemic on a global scale, and been reduced to near-elimination, all within the span of documented medical history"
"Epidemics of the disease appeared in the late 19th century in many European countries and North America, following which polio became a global disease with annual epidemics."
"Beginning in 1955, the creation of poliovirus vaccines led to a stepwise reduction in poliomyelitis, culminating in the unpredicted elimination of wild polioviruses in the United States by 1972."
"Global expansion of polio immunization resulted in a reduction of paralytic disease from an estimated annual prevaccine level of at least 600,000 cases to fewer than 1,000 cases in 2000."
