Administrators at Palm Desert High School in California have banned 66 students who never got measles vaccinations.
"I think some parents see it as a personal choice, like homeschooling. But when you choose not to vaccinate, you're putting other children at risk." From WaPo: Why this baby's mom is so angry at the anti-vaxxers.
"I respect people's choices about what to do with their kids, but if someone's kid gets sick and gets my kid sick, too, that's a problem." A Marin County father has demanded that his district keep unvaccinated kids out of school.

Today's Google Doodle honors Jonas Salk on what would have been his 100th birthday. Salk developed the first successful polio vaccine in 1955 and was hailed as a hero for it.
On April 12, 1955, Dr. Thomas Francis, Jr., of the University of Michigan, the monitor of the test results, "declared the vaccine to be safe and effective." The announcement was made at the University of Michigan, exactly 10 years to the day after the death of President Roosevelt. Five hundred people, including 150 press, radio, and television reporters, filled the room; 16 television and newsreel cameras stood on a long platform at the back; and 54,000 physicians, sitting in movie theaters across the country, watched the broadcast on closed-circuit television. Eli Lilly and Company paid $250,000 to broadcast the event. Americans turned on their radios to hear the details, department stores set up loudspeakers, and judges suspended trials so that everyone in the courtroom could hear. Europeans listened on the Voice of America. Paul Offit writes about the event:
"The presentation was numbing, but the results were clear: the vaccine worked. Inside the auditorium Americans tearfully and joyfully embraced the results. By the time Thomas Francis stepped down from the podium, church bells were ringing across the country, factories were observing moments of silence, synagogues and churches were holding prayer meetings, and parents and teachers were weeping. One shopkeeper painted a sign on his window: Thank you, Dr. Salk. 'It was as if a war had ended', one observer recalled."
Because of Salk's vaccine and subsequent vaccines, the US has been polio-free since 1979.
Measles cases in the U.S. just hit a two-decade high. In case you can't already guess why, assistant surgeon general Dr. Anne Schuchat explains:
The current increase in measles cases is being driven by unvaccinated people.
From Aeon, Polio whack-a-mole:
The great allies of infectious diseases are no longer poverty, nor dirt, but the global anti-vaccination movement.
In a clinical trial at the Mayo Clinic, a woman with a type of blood cancer called myeloma was given an injection of measles virus large enough to innoculate 10 million people and has been "completely cleared" of her cancer.
So, as part of a two-patient clinical trial, doctors at the Mayo Clinic injected Erholtz with 100 billion units of the measles virus -- enough to inoculate 10 million people.
Her doctor said they were entering the unknown.
Five minutes into the hour-long process, Erholtz got a terrible headache. Two hours later, she started shaking and vomiting. Her temperature hit 105 degrees, Stephen Russell, the lead researcher on the case, told The Washington Post early Thursday morning.
"Thirty-six hours after the virus infusion was finished, she told me, 'Evan has started shrinking,'" Russell said. Over the next several weeks, the tumor on her forehead disappeared completely and, over time, the other tumors in her body did, too.
The cancer of the other person in the trial was unaffected and larger randomized trials still have to be performed, but this is encouraging news. Between this and the remission of cancer using HIV, it looks like viral therapy has a real shot at being a powerful weapon in fighting cancer.
In 1988, India had over 200,000 cases of polio reported. For the past three years, they've had 0. At the end of this month, the WHO will announce the end of polio in India.
America experienced the height of polio in the 1940s and '50s, when about 35,000 people became disabled every year. Fear and panic spread and parents were known to warn their children to not drink from public water fountains, avoid swimming pools and stay away from crowded public places like movie theaters. Perhaps the most famous case of polio in America was Franklin Delano Roosevelt, the first president with a significant physical disability.
The development of the Salk and Sabine vaccines helped lead to eradication of polio in the United States in 1979. In India, too, vaccination was critical.
"There were three keys to our success," Kapur says. "Immunize, immunize and immunize."
Vaccines. And now my kids don't die.
Amy Parker grew up with super health-conscious parents who provided her with a healthy diet and active lifestyle. But they also didn't vaccinate her and she was sick all the time as a kid.
As healthy as my lifestyle seemed, I contracted measles, mumps, rubella, a type of viral meningitis, scarlatina, whooping cough, yearly tonsillitis, and chickenpox. In my 20s I got precancerous HPV and spent six months of my life wondering how I was going to tell my two children under the age of 7 that Mummy might have cancer before it was safely removed.
This is the part that really gets to me: Parker wasn't vaccinated but was given so many antibiotics for her childhood illnesses that she became immune to them! [Hair-tearing-out noise]
My two vaccinated children, on the other hand, have rarely been ill, have had antibiotics maybe twice in their lives, if that. Not like their mum. I got so many illnesses requiring treatment with antibiotics that I developed a resistance to them, which led me to be hospitalized with penicillin-resistant quinsy at age 21 -- you know, that old-fashioned disease that supposedly killed Queen Elizabeth I and that was almost wiped out through use of antibiotics.
Update: Slate has corrected the passage above, taking out the part about Parker's resistance to antibiotics. It now reads:
My two vaccinated children, on the other hand, have rarely been ill, have had antibiotics maybe twice in their lives, if that. Not like their mum. I got many illnesses requiring treatment with antibiotics. I developed penicillin-resistant quinsy at age 21 -- you know, that old-fashioned disease that supposedly killed Queen Elizabeth I and that was almost wiped out through use of antibiotics.
People do not develop antibiotic resistance, microorganisms do. I regret the idiotic error and tearing out my hair. (thx @chrismize)
What if there were a new class of wonder drugs for children that prevented some of the worst diseases in history with very limited side effects...would you take them?
Some people don't "trust" that wacky "science" though.
What's so confounding is that many of the parents requesting exemptions for their children cite specious, disproven fears -- such as that the vaccine could cause autism -- many of which were based on a fraudulent, retracted study or fringe research published in non-peer-reviewed journals. And the rest of the country hasn't been as successful as Massachusetts in containing measles infections. Earlier this year, an intentionally unvaccinated 17-year-old from Brooklyn, New York, was infected with measles while on a trip to the United Kingdom. Because he lived in a community with a large number of other deliberately unvaccinated children, the virus quickly spread. By the time the outbreak was contained, 58 people had been infected -- making it the largest outbreak in the country in more than 15 years. Nationwide, the Centers for Disease Control and Prevention reported 159 total cases between January and August, which puts 2013 on track to record the most domestic measles infections since the disease was declared eliminated from the United States in 2000.
Declared eliminated! [Hair-tearing-out noise]
From The New Yorker: Jenny McCarthy's Dangerous Views. She's been hired as a new host on The View. Some worry that we'll be hearing a lot more about her anti-vaccine postions. Of course, if you are making life-decisions based on the views of people on The View, you might want to consider the host who thought the world might be flat.
An article from a mother who was anti-vaccine until her daughter (and then the rest of the family) got the whooping cough. And still she feels "funny" about vaccination.
And yet I still wondered about that list of things that I would now, I suppose, have to surrender to and immunise my child against. Polio, for one -- a couple of my parents' pensioner friends still carry the limp left by their childhood polio, but none of my friends do, because it isn't around any more. And diphtheria -- what was that, even? I knew it had killed one of Queen Victoria's daughters, but that wasn't our reality.
The reason it wasn't our reality was, of course, due to a continuous programme of immunisation. Duh. Diphtheria is a disease that still kills one in five infants it meets, even if they get treatment, their necks swelling up until they can no longer breathe. I have now seen a picture of a child whose neck was ravaged by diphtheria, bloated like a foie gras goose about to burst. I wish I could unsee it.
Duh, indeed. This anti-vaccination nonsense is an instance in which the public's lack of knowledge about how science works (and not just their lack of recall of scientific facts) is truly harmful. (via @CharlesCMann)
The Jenny McCarthy Body Count site tracks the number of vaccine-preventable illnesses and deaths in the US since June 2007.
In June 2007 Jenny McCarthy began promoting anti-vaccination rhetoric. Because of her celebrity status she has appeared on several television shows and has published multiple books advising parents not to vaccinate their children. This has led to an increase in the number of vaccine preventable illnesses as well as an increase in the number of vaccine preventable deaths.
I hadn't realized just how much of a nutter McCarthy is...her embrace of pseudoscience runs deep.
Indigo children is a term used to describe children who are believed to possess special, unusual and sometimes supernatural traits or abilities. The term is pseudoscientific. The idea is based on New Age concepts developed in the 1970s by Nancy Ann Tappe and further developed by Jan Tober and Lee Carroll. The concept of indigo children gained popular interest with the publication of a series of books in the late 1990s and the release of several films in the following decade. A variety of books, conferences and related materials have been created surrounding belief in the idea of indigo children and their nature and abilities. The interpretations of these beliefs range from their being the next stage in human evolution, in some cases possessing paranormal abilities such as telepathy, to the belief that they are more empathic and creative than their peers.
Some pediatricians are asking families who refuse to vaccinate their children to leave their practices.
For Allan LaReau of Kalamazoo, Mich., and his 11 colleagues at Bronson Rambling Road Pediatrics, who chose in 2010 to stop working with vaccine-refusing families, a major factor was the concern that unimmunized children could pose a danger in the waiting room to infants or sick children who haven't yet been fully vaccinated.
In one case, an unvaccinated child came in with a high fever and Dr. LaReau feared the patient might have meningitis, a contagious, potentially deadly infection of the brain and spinal cord for which a vaccine commonly is given. "I lost a lot more sleep than I usually do" worrying about the situation, he said.
"You feel badly about losing a nice family from the practice," added Dr. LaReau, but families who refused to vaccinate their kids were told that "this is going to be a difficult relationship without this core part of pediatrics." Some families chose to go elsewhere while others agreed to have their kids inoculated.
Jenny McCarthy just won't call it quits on the whole vaccines cause autism thing. Cause she's a mom! And moms love their children! And are strong! QED. And of course this was published by Huffington Post, the blog equivalent of Jenny McCarthy.
As if there was actually more evidence needed that vaccines don't cause autism, the 1998 British study that linked autism to childhood vaccines was recently discovered to be an elaborate fraud. Not just incorrect, a fraud.
An investigation published by the British medical journal BMJ concludes the study's author, Dr. Andrew Wakefield, misrepresented or altered the medical histories of all 12 of the patients whose cases formed the basis of the 1998 study -- and that there was "no doubt" Wakefield was responsible.
"It's one thing to have a bad study, a study full of error, and for the authors then to admit that they made errors," Fiona Godlee, BMJ's editor-in-chief, told CNN. "But in this case, we have a very different picture of what seems to be a deliberate attempt to create an impression that there was a link by falsifying the data."
The full paper from BMJ is here.
The debate is essentially over and the final word is in: vaccines do not cause autism. The results of a rigorous study conducted over several years were just announced and they confirmed the results of several past studies.
Basically, the final two groups that were studied consisted of 256 children with ASD [autism spectrum disorders] and 752 matched controls. One very interesting aspect that looks as though it were almost certainly placed into the experimental design based on concerns of anti-vaccine advocates like Sallie Bernard is a group of children who underwent regression. Basically, the study examined whether there was a correlation between ASD and TCV [thimerosal-containing vaccines, i.e. mercury-containing vaccines] exposure. It also examined two subsets of ASD, autistic disorder (AD) and ASD with regression, looking for any indication whether TCVs were associated with any of them. Regression was defined as:
"the subset of case-children with ASD who reported loss of previously acquired language skills after acquisition."
Also, when adding up total thimerosal exposure, the investigators also included any thimerosal exposure that might have come prenatally from maternal receipt of flu vaccines during pregnancy, as well as immunoglobulins, tetanus toxoids, and diphtheria-tetanus. In other words, investigators tried to factor in all the various ideas for how TCVs might contribute to autism when designing this study.
So what did the investigators find? I think you probably know the answer to that question. They found nothing. Nada. Zip. There wasn't even a hint of a correlation between TCV exposure and either ASD, AD, or ASD with regression:
"There were no findings of increased risk for any of the 3 ASD outcomes. The adjusted odds ratios (95% confidence intervals) for ASD associated with a 2-SD increase in ethylmercury exposure were 1.12 (0.83-1.51) for prenatal exposure, 0.88 (0.62-1.26) for exposure from birth to 1 month, 0.60 (0.36-0.99) for exposure from birth to 7 months, and 0.60 (0.32- 0.97) for exposure from birth to 20 months."
The last result is a bit of an anomaly in that it implies that exposure to TCVs from birth to 1 month and birth to 7 months actually protects against ASD. The authors quite rightly comment on this result thusly:
"In the covariate adjusted models, we found that an increase in ethylmercury exposure in 2 of the 4 exposure time periods evaluated was associated with decreased risk of each of the 3 ASD outcomes. We are not aware of a biological mechanism that would lead to this result."
So get your kids (and yourselves) vaccinated and save them & their playmates from this whooping cough bullshit, which is actually killing actual kids and not, you know, magically infecting them with autism. Vaccination is one of the greatest human discoveries ever -- yes, Kanye, OF ALL TIME -- has saved countless lives, and has made countless more lives significantly better. So: Buck. Up.
