I like the idea of Pfizer's being a one shot, but herd it is kind of hot

Covexin Plus. Everything that Pfizer's Ultrachoice 8 has, plus tetanus. Think it is cheaper too. :cowboy:

We use the alpha-7, like the one shot deal but it does leave a whelp most of the time. Big deal.

We use the Alpha-7 also, but if you shoot it right in front of the front leg, it wont leave a knot or whelp.
Neck shots seem to usually leave a knot of somekind.

I use all pfizer Vaccines because of marketing mainly my buyers want it and I also get a deal on the Vaccines

 

[Stocker Steve]

Can you use any of these on bred cows?

We use one called Tasvax, they have a couple different ones, one covers tetnus, and I prefer it.

I've noticed a 16ga needle will leave less whelps than an 18ga.
