Snake Vaccine Needed

I need to locate a few vials of snake vaccine. Please let me know if you have any ideas. I'm in Fort Worth but willing to drive. I just need the vaccine itself but if you know of a Vet nearby that provides shots let me know.

I had a friend buy a case last year and I gave my dogs the vaccine but now I need a booster and he doesn't have enough.

Can't your vet order it for you?

Campbell Park Animal Clinic in Garland has it.

The pet clinic that visits tractor supply every Sunday told me they carry it.
