And the answer is simple: vaccinate.
It's true vaccines don't work 100% of the time. But generally the small percentage of times they don't work, the person is protected anyway because everyone around them has been successfully vaccinated. This only becomes a problem when people selfishly or gullibly opt out of getting their children vaccinated.
Notice the details of some of the outbreaks: one of them happened at a private school where many of the parents failed to get their kids vaccinated. If your kids are around a lot of kids who haven't been vaccinated, they're also in danger.

"...half the children were not vaccinated..." Hmmmm does that not tell you the other HALF WAS VACCINATED? Half is not a small percentage as you suggest. Why do the children not vaccinated get the blame? It's the children who receive the LIVE VIRUS, when vaccinated, are the ones who need to be avoided for the first several days of receiving it!
"....officials say they (the vaccines) are perfectly safe" One wonders.... how much kick back do these "officials" get from pharmacuiticals? The jury is still out on the safety of this stuff we put into our precious children. As the number of vaccines, given to each child, has increased, the number of autistic children has increased. One might ask who are the gullible ones!
I read that editorial several times and tried to notice the details......no where did I see it indicate one of the outbreaks happened at a private school.

To "another perspective"

Where were you in math class. The number of cases used to number in the hundreds of thousands. Now with vaccination, the number has dropped to 131 cases. Yeah, about 65 of those kids where vaccinated. 65 out of hundreds of thousands in not 50%.

Guess what, as the number of vaccines has increased, so have the number of cars on the road. That does not mean the two are correlated. Why not head back to a stats class.

Just wait for Polio to make a comeback.. I'm sure all the people suffering from vaccine-phobia will come running back. We are so spoiled these days, we didn't live through these horrible diseases like they did just a few years ago.
