I have been using up my bottles of CDT for 13 years on alpacas. In the 13 years that I have owned them and also vaccinated hundreds of others alpaca crias with my bottles of CDT, there has been NOT ONE that has died from tetanus or clostridium. Believe me, if someone lost their cria due to tetanus or clostridium, they would be calling me and demanding payment for their lost cria.

I do make sure that I use up my bottle by the end of the year and buy a new one in the spring. Most of the time, this isn't a problem for me since I vaccinate so many alpacas and now goats. Everyone that I know keeps their bottle until they use it up or it expires.

Antitoxin, B vitamin shots, Penicillin, oral electrolytes, lots of TLC, we chopped up alfalfa cubes and drenched her w/ that and oatmeal soaked in water.
The vet gave her a shot of steroid as well....she lost her kids, but we saved her.

The longest period of time I've ever seen recommended to store an opened vial of killed vaccine in the fridge is 10 days -- and that's only if it contains a preservative like thimerosal.
I would think it wouldn't matter as much with killed vaccine, only modified live.

Ok, so, why is it then that ALL biologicals instruct the consumer to use the entire contents when the vial is first opened, or pitch it?

It's not the CYA thing, because there are plenty of example of non-antibiotic multi-dose vials out there... Right off the top of my head, the multi-dose vials I have in my own cabinet include vit. B complex, Bo-Se, lutalyse, banamine, dexamethasone, etc..

Why do none of those state to use it all at once if using it all at once is merely a CYA thing we can ignore just as we do the label on a box of q-tips that basically says 'WARNING: DON'T STICK THIS IN YER EAR.'

There's gotta be something else to it..

Liability, plain and simple. I've worked in medical facilities (nursing homes and rehabilitation centers mostly) in quite a few states. Every state has their own mandates and regulation invoved, but every facility I've worked at has used their meds to the last drop or expiration date. This includes antibiotics, innocculants, vitamens, hormones, insulin,ect. Stands to reason that if it's good enough for humans then it should be for livestock. I believe the only reason they put "toss after use" is because they expect us to be filthy cretins that don't know how to use a sterile needle each time, and as someone else said, they're pitchin to the lowest end of the spectrum.

But again, there's a HUGE hole in that logic... Go look at your 250ml vial of b-complex and see if it has that same warning. Or your vial of Lutalyse. Or your vial of Bo-Se.. Or your vial of Ivomec injectable..

They don't carry that warning.

Indeed, you'll probably find the words "multi-dose vial" printed somewhere on the labels, specifically noting that it's OK to set it back on the shelf and come back for another dose later.

So, if it were strictly a liability situation and the concern was that some cretin would stick a dirty needle back in the vial, contaminate it, let it incubate, and then proceed to kill all the rest of his animals with it....EVERY VIAL of EVERYTHING would be labeled "use entire contents," just like biologicals are labeled.

But, again, everything's NOT labeled that way...

Why is that?

IMHO (for what that's worth....)

The difference is that vitamins, supplements, dewormers, etc. aren't meant to prevent illness by causing an immune reaction.

A bottle of CD&T that is proven bad could be a bigger liability (if a herd broke out sick) than a bottle of B12 that's past it's prime.

I've read all your arguments, CM, and thought about what you've written... but you're not swaying me.
Like I said, I KNOW we have tetanus in the ground here thanks to Mbuzi....and the vaccines I've given (out of bottles that've been used over a period of 6 mos or more...are obviously working....I still say it's a CYA thing.
My vet uses the same vaccine bottle until it's empty, I figure she spent the big bucks to learn if that's ok or not....and that's good enough for me.

Alrighty. :)

Keep in mind that I'm not necessarily trying to slam anybody or anything like that...it just seems odd to me that it would be a CYA thing, given how many vials are labeled "multi dose"..

And if it turns out to be strictly a CYA thing, I'll probably start saving vax myself. I *will* find out what the reason is, though....somehow.

I really just want to know...ya know?
