Question about Prodigy (killed Rhino)

[Kari]

I have 3 killed rhino shots that expired in March. Think they're ok to use still? I'd use them by late Jan.

Our vet has told us that as long as they they've been kept fridged, you shouldn't have a problem using them for a year passed the expiration date. After that, they start losing their effectiveness.
