Bovi Shield Gold FP5 VL5 HB:
This is a MLV vaccine (IBR , BVD , PI3, BRSV) with Campylobacter fetus (Vibriosis) and 5 way Leptospira, plus you have the Hardjo Bovis serovar. You should vaccinate 4 to 6 weeks prior to breeding.
In the circumstances you provided, the cow is open, obviously, without saying, there is no danger of abortion. Personally, I would give her 5 days postpartum to adjust then vaccinate. However, some recent research on MLV Vaccines was reported to interfere with ovary cycles (Dr. Michelle Arnold, University of Kentucky). So you should be aware of that and give the cow 4 to 6 weeks to react to the vaccine before breeding her back.
The calf can be vaccinated at 1 to 3 months old. Or you can use an intranasal like Inforce 3 at birth.

Good post Ron, we vaccinate calves with intra nasal at birth and again at branding. Sometimes only 2 weeks apart. Not always the best protocol but best we can do considering all aspects. Cows are vaccinated with Vista Once which contains a pasturelle component that we discussed before the same day their calves are branded. Most of our cow herd is done at least 5 weeks before bulls go out. A few stragglers might only be a week vaccinated before bull turnout but likely won't be the first to cycle anyway.
This is what I had always preached & read - but - new research has proven all this information to be false - supposedly.Dempster":jh6t5923 said:Calves need to be about 3 months old prior to vaccinating to prevent significant maternal interference from the dam's colostrum. The FP product is the reproductive version of the vaccine, it should be given 30-60 days before turning out the bull. The calf does not need all that in it's vaccine and would be better off without it. Just use the straight bovi-shield gold 5.

But, here is an excerpt from an article I had in a newsletter:
"As the calf ages, the colostral immune globulin levels start to drop off over time, and are mostly gone by around 3-4 months of age. This is an important concept to understand for two reasons: First, giving the calf an injectable vaccine before this time frame means that any antigens for diseases you are vaccinating for (IBR, BRSV, PI3, etc.) will be neutralized by the immune globulins delivered in the colostrum. Essentially, if you have vaccinated the pregnant cow for those same diseases, and the calf nursed properly, there is no need to deliver those same vaccines to the calf prior to 4 months of age.
The second reason not to give an injectable vaccine before this time frame is that the calf's immune system is not ready to see and react to the vaccine. It takes time for the white blood cells responsible for the development of a systemic immune response to learn their jobs and be able to react to invading bugs. One important exception to the use of vaccines in young calves is the use of intra-nasal vaccines. These vaccines provide a localized immunity in the nose very quickly, and are not interfered with by colostral immunity. This is why these vaccines can be given immediately after birth, and at any time in the production cycle safely and effectively."
