Welcome, Sheena! Sorry you need to be here, but there are worse things!
It is true that there is a shortage of BCG. Only one company produces it for sale in the US and this is a subsidiary of
Merck. BCG is a biological product, just as vaccines are, and depends on the "goodwill" of bacteria for its manufacture. If something goes wrong, or contamination sets in, the entire process needs to be stopped and restarted. Merck has said that the shortage should be over by September. They have been severely limiting shipments so your husband is not the only one missing out.
The good news is that your husband has had two treatments and that should have at least started to kick up his immune system. There is no set protocol for BCG; often after several treatments irritation sets in and the treatments need to be postponed for several weeks to allow the bladder to heal. If bacteria are present in the urine BCG will not be given until that is cleared. This does not hinder the effectiveness of BCG. Your husband should be OK and the treatment should be available in the near future.
As for communication issues, was the information about his diagnosis given in person at an office visit? Could the woman have been a fellow urologist in the office? If your husband does not feel comfortable with this practice he could always seek a second opinion elsewhere. However, for the present, he is "in line" for the BCG supply with this office so it might be a good idea to stay put until he has had the six initial treatments. I assume that they will recommend maintenance treatments, which go on intermittently for about two years, so he might switch, if he is so inclined, before they start.
Good luck

It is unfortunate that the urologist did not explain this possibility at the start.
