Hi Karin,
There's a very important label on every vaccine vial. It applies to Moses. It says, essentially, "Only for use in healthy animals." A chronic sinusitis? Not healthy, right? You can read more about this on this post. He's got a waiver, even if Dr. WhiteCoat doesn't think this way, you can and certainly should, on Moses' behalf.
