Measles Truth
Its well established that vaccines typically don't last forever. This is the reason for booster shots. Every vaccine researcher and pharma company will tell you when you need a booster to get your immunity to last into adulthood. Once you are an adult you are irrelevant.
The reason we immunize children is because their hygiene practices are poor. Poor hygiene leads to more diseases which makes adults look for easy solutions.
Adults do not immunize because the risk/reward profile simply isn't worth it. Every shot, vaccine or not, is a risk. On the other hand, adult-quality hygiene and typical first world nutrition cause people to avoid many of these diseases. For a recent example look at Ebola. Many people simply can't get it because they are too healthy. This is why ebola never went anywhere in the USA and many other countries.
Most people aren't aware that the USA stayed polio-free for many years while a live attenuated virus was given to children. It was known that the live attenuated virus became a full strength virus in the child's stool. Look it up, at least one American woman caught it from changing a diaper. Now we use dead virus but the point is that for millions of diaper changes, there just wasn't a problem. Other countries with the live vaccine had huge problems. The difference? Hygiene and nutrition.
Vaccines are a voluntary tool. People who choose not to use them are not a problem.
And finally, please note that no one died of measles and many were hospitalized for precaution, not an actual need. Healthy, first world people rarely die from measles. I know it doesn't sell newspapers but this was not a deadly epidemic. All of the angry rhetoric around this event could have been avoided if the media stated the fact that there would be no deaths in otherwise health people. Meanwhile, heart disease is a deadly epidemic and there is no vaccine for that.
