Thousands of un-vaccinated illegal immigrant children were allowed to cross our border last year and then were placed into the public schools systems throughout the USA. This year, we have an outbreak of measles. Vaccinations do not fully protect anyone. Even people who have been vaccinated for measles are coming down with measles. This is why no one should be allowed into the USA unless they are properly vetted and insured that they do not bring diseases with them into this country. For the small amount of parents in this huge country who do not vaccinate their children (and this has been going on for decades) we should not be seeing an outbreak of this magnitude. If it is true that they are to blame, this type of outbreak would have happened years ago. It's only happened now since thousands of illegal immigrant children arrived here last year.
If vaccination solves the problem, then "your" vaccinated kid should not be affected. Kids that can not be vaccinated because of health reasons such as cancer or other/s, should not be in public schools. Vaccinated people have been known to come down with the illness they are vaccinated against. Too risky to put sick kids in with the general public. Look at the flu shot. It has not helped anyone. I was vaccinated against measles as a child. Now I'm hearing doctors say there is no guarantee that I'm still protected and should be vaccinated again. So in other words, everyone who was vaccinated as a child and is now 40 or more years old are also contributing factors to the continuation of the disease. That's how I see it from what the doctors said. We are no better than the non vaccinated children if we need to be vaccinated again. It's all a scam for the pharmaceutical companies to cash in since the Ebola outbreak went no where.
