Doctors firing families who refuse vaccines

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 still confused

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.


Autism study fraudulent

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 โ€” 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.


Vaccines don’t cause autism

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 โ€” yes, Kanye, OF ALL TIME โ€” has saved countless lives, and has made countless more lives significantly better. So: Buck. Up.
