For the past five years, there have been large outbreaks of infectious laryngotracheitis (ILT) in chickens in Australia. ILT is a highly contagious herpesvirus, and one of a group that includes herpes and chickenpox. The chickens become very ill with red and swollen eyes, along with sneezing, coughing and gasping, while occasionally producing a bloody nasal discharge. Mortality is quite high, and surviving chickens produce fewer eggs, which, of course, is very bad for chicken farmers.
The diseases are usually prevented by a vaccine against ILT. Many vaccines against viruses, including the ILT version, contain live attenuated viruses (LAV), which are viruses that have reduced virulence, though still alive, so that the immune system recognizes it to develop an immune response. Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent.

As I discussed a few days ago, Meryl Dorey, the anti-vaccination crackpot, used her vaccine denialist Australian Vaccination Network (AVN) to set up the Real Australian Sceptics in a laughable and amateur attempt to co-opt the word “skepticism” by starting a website that is pure, unadulterated pseudoskepticism. In case you’re wondering, a pseudoskeptic (using the term as defined) refers to those who declare themselves merely “skeptical” of a concept, but in reality would not be convinced by any evidence that might be presented. Global warming “skeptics” are in fact pseudoskeptics who deny the evidence for global warming. Vaccine skeptics are really just pseudoskeptics who deny all of the evidence that shows vaccine’s benefits far exceed the small risks. And that there are no risks of vaccines causing autism.

It’s clear that Meryl Dorey, founder of the Australian Vaccine Network, is the very symbol of vaccine denialism, using all sorts of pseudoscientific stupidity to support her unsupportable beliefs. Those beliefs have lead to the various whooping cough, measles, and other infectious disease outbreaks in Australia, Canada, the US, and the UK. Admittedly, she’s not the primary cause of this type of denialism (we can blame Mr. Andy Wakefield for his fraudulent research that lead to Dorey’s particular brand of denialism).
It gets worse. Or funny. Maybe both.

The junk science and outright lies that can be found on the internet is enough to make one wonder if it’s even possible to cut through this noise to present what is actually scientifically and medically sound. Every day, there’s new internet meme that makes some outrageous, and barely rational, claim. If you produce expensive urine, it will prevent cancers. Or experiments on monkeys prove that vaccines cause autism. Or Mayans, who couldn’t even predict that Spanish Conquistadors were going to invade, supposedly predicted the end of the world in 2012. Seriously, why do people listen? Maybe that’s why a lot of bloggers take the time to debunk this stupidity, in the hope that someone researching some pseudoscientific claim, finds a few skeptical blogs that use snark, science, and logic to discredit them. Some blogs use all three!

According to the Vaccine News Daily, Australian sees sharp rise in whooping cough cases. In 2011, Australia has seen about 38,000 cases of whooping cough, despite a relatively high level of vaccination. As a comparison, California, which has about 15 million more people than Australia (37 million and 22 million people, respectively) had only 3,000 cases of whooping cough in 2011. Some of the difference may be related to improved diagnostic procedures, but they have also been implemented in California.
