Rather than getting all these vaccines repeatedly for bacterial or viral respiratory illnesses, perhaps a course of oral doses of ivermectin could be used.
Was the coronvirus/adenovirus treatment oral ivermectin for 5 days? That would probably work for all animals. Just need to figure out the dosage.
Subcutaneous if really necessary. But oral is obviously safer and easier.
So would you use it to treat respiratory diseases such as avian flu, or general RSV in animals?
Since they might roll out avian flu, it might be good to have this in our back pocket.
I would use metronidazole and ivermectin for respiratory or digestive problems. Metronidazole or brand name Flagyl is used as a experimental treatment for chronnes disease.
