The moving goalposts of the anti-vaccine arguments can be annoying. First, it was mercury (no mercury in vaccines). Today, it’s aluminum and vaccines. What next, the water in vaccines causes something because of reasons?
There is overwhelming and solid evidence that the tiny levels of aluminum in some vaccines are biologically irrelevant. Of course, the anti-vaccine religion is rarely convinced by science, because of only their beliefs matter.
The anti-vaxxers have a preconceived conclusion that vaccines are dangerous – aluminum and vaccines cause it. Then they find every bit of “evidence” to support that conclusion, irrespective of the mountain of evidence that says they are wrong.

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. Continue reading “Chicken vaccine viruses recombine in wild, anti-vaccine conspiracies abound”
