I'm not from Oregon either, but I vaccinate all the cows yearly with Virashield 6 with VL5 , Covexin 8 (or similar brand) and added this fall , Scour Bos 9.
If you are having a problem with pinkeye, I think you will be better off and money ahead to have your vet do a culture and send it off and have them develop a vaccine for the type you have. There are many different forms of pinkeye and this would save $$$ in that you would be giving them a dose of the type that is affecting them. I had a problem with pinkeye a couple years ago and even though I vaccinated for the pinkeye, it was not the type they had. My pinkeye was the one that affects sheep. I had the vet do a culture on one and he sent it off and had the vaccine made for me.
Blood and guts don't bother me but when the vet gave the cow a shot in the eye to clear it up, I nearly had the dry heaves.
