There's so much misinformation in that article.... as with so many anti-vaccine articles.
The article is about this report:
The report doesn't say that "vaccines don't work." It certainly doesn't say that vaccines cause autism (as the article you linked to says without any citation to authority whatsoever).
What the report mentions is that, for example, out of 630,157 recipients of the MMR vaccine, there were 311 meningintis cases that were vaccine-related. And, that about 89% of these meningitis cases resolve themselves, while 11% of them cause permanent side effects.
So, basically, if you're innoculated against measles, mumps, and rubella, you have roughly a 0.05% chance of getting meningitis, and roughly a 0.005% chance of suffering permanent nerve deafness, etc.
The article claims that the UK suppressed information about those risks, and I suppose that's a legitimate policy complaint.
The only thing it says about "ineffectiveness" is that when MMR was withdrawn for a short period of time, there wasn't an outbreak of measles. But of course that's unsurprising, since when you suppress a population of any organism, it doesn't rebound immediately.
