Just speculating, but a medicine doesn't have to work for it to be adopted as the norm. See remdisivir. Which not only didn't work but was actually deadly. OR AZT. A loose correlation (provided by a study commissioned the manufacturer), and no bad side-effects would probably be enough to have a medicine be declared as the permanent standard of care for a particular illness these days. Medicine/Allopathy has been quite corrupt for many decades, and I guess that could include animal medicine.
Oh lol, I just searched for the kennel cough vaccine and the top related searches are 'bordella vaccine killed my dog'. I don't know if this is true or not but then there are various articles countering claims of death because vaccines are safe and effective. So... Huh.
