For those of using Inforce 3 as part of your newborn health protocol. How do you manage it since it is a vaccine that has to be rehydrated and used right away? Do you wait until you have enough calves to use the whole vial? Maybe some of you have 10 or more born within a day or two of each other, but some of us will take 2 - 3 weeks to get 10 new calves to utilize a whole vial and not waste it. Can it be kept refrigerated for a few days or more after rehydrating? How long is accetpable to wait after birth to get the newborn vaccinated and still be a beneficial procedure?
