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.
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.
