THE M-M-R VACCINE WEARS OFF / DOES NOT WORK????

I was just looking the frequently ask questions from the NHS about the MMR (MUMPS, MEASLES, RUBELLA) VACCINE and I REALLY have to ask HOW F#CKING STUPID DO THEY THINK WE ARE???? The logic being used is absolutely ABSURD!!!! BELOW ARE A FEW HIGHLIGHTS OF THE STUPIDITY!!!!

How long does protection from MMR last?

It seems to be very long lasting. Virtually everyone (more than 99%) will be protected against measles and rubella for more than 20 years after two doses of MMR.

Protection against mumps after two doses of MMR is a little lower (90-95%) and appears to gradually decline. Mumps in vaccinated people is, however, much less likely to lead to complications such as meningitis or orchitis (painful swelling of the testes) and vaccinated people are less likely to require admission to hospital.

WTF??? MUMPS IS A SELF LIMITED DISEASE AND IS MILDER THE YOUNGER YOU ARE! THE SAME GOES FOR MEASLES! Natural measles gives you life long protection BUT if you notice they claim the MMR protects for over 20 years. I call bullshit on this and think many of the recent outbreaks are from the vaccine wearing off. Yet another reason to seek out the childhood diseases and have them over and done with! Natural immunity is the ONLY immunity!
Take a look at their contradictions on the NHS website and notice that the UK has ONLY the MMR since 1988!!!! Prior to this MUMPS was NOT seen as a big deal, funny how that changes when you can push a vaccine...  ADDING TO THE INSULT IS THE CONTINUED DENIAL OF VACCINE INJURY, I MEAN REALLY WTF... :-( :-( :-(
