There have been recent measles outbreaks in the United States -- which have led many to claim that this is likely related to "anti-vax" sentiment and "personal exception" laws for vaccination.

(CNN)So far this year, Washington state is averaging more than one new measles case a day as officials try to help stop the disease's spread.

Since January 1, Clark County Public Health has confirmed 47 cases of measles. In King County, home of Seattle, at least one confirmed case was reported.

A vast majority of those who came down with measles -- 41 -- were not vaccinated against the disease, Clark County officials said. One patient did receive a vaccination against MMR (measles, mumps and rubella), but the health agency declined to provide more details on that case "to protect the patient's privacy."

Measles is a nasty disease.  It is not simply "a rash, a fever, and then it's over" sort of thing.  In a small but significant percentage of the people who get it the infection spreads to the brain or causes a secondary pneumonia condition to arise; both can permanently injure or kill.

The MMR vaccine is allegedly about 97% effective in providing immunity if you get both doses (one at about 12 months, and the second between 4 and 6 years of age.)  The problem is that we admit into this country a huge number of individuals who have no vaccinations in this series and sometimes none at all, nor do we track them.  They're illegal invaders.

"Herd immunity" is often claimed as the reason to require everyone be vaccinated.  But that claim is bullshit; herd immunity is the phenomena that drops the transmission efficiency of a given disease below 1.0.  Measles is extraordinarily contagious, however -- a single person who has it and is contagious that comes in contact with 1,000 non-antibody carriers (either through previous exposure or vaccine) will likely infect an utterly enormous percentage of those exposed.  While it is true that in vaccinated populations transmission will eventually die out due to herd immunity those who have vaccine failure -- and a single-digit percentage of those vaccinated are not protected -- are still nearly-certain to contract the disease if they are exposed.

The bottom line issue here is that illegal immigration is a monstrous vector problem and one we can put a near-100% stop to by stopping all invasion of this nation by those who are not vaccinated.

Again, while a wall or other hard border barrier will not stop all persons from coming into the country illegally it will stop more than 90% of them immediately.  That's the record other nations with border walls have -- including Israel.

If you decide for whatever reason not to vaccinate your kid(s) then your kids are the ones primarily at risk.  But those who did take the vaccine and have it fail for reasons entirely beyond their control, simply because it doesn't always work, should not be exposed to the risk of serious disease and even death simply because some jackwad politicians and businesspeople want political favors and cheap under-the-table illegal labor.

Those who advocate for illegal immigration and protection of any who cross illegally and are already here ought to be charged as accessories before the fact with manslaughter should any US Citizen die as a result of such an infection and be hung at the national mall in fulfillment of their sentence.
