Beef cattle producers can use the following BVD Vaccination Cost-Benefit Calculator to evaluate the costs, benefits and risks of different bovine viral diarrhea virus vaccination and outbreak scenarios.

Assumptions
Typical prevalence of abortion from BVD for vaccinated cows: 6%
Unvaccinated cows could have abortion rates ranging from 6.7% to 58.9% and averaging 20%*
* Estimated based on typical prevalence of abortion from BVD at 6%, using the odds ratio and confident intervals. Odd ratio for abortion when unvaccinated cow in community pasture vs. vaccinated cow sourced from Theurer et al., 2015.
Notes:
While it is recognized that a BVD outbreak at a cow-calf operation could also cause calf death loss, and BVD vaccination could postively affect pregnancy rates, there is no suitable data (that is statistically significant) to include in this analysis.

Step 3. Flow Chart
Yes
Your vaccine investment is $4.03 /head, if you include your labour and the vaccine shot.
No
You’ve saved some money and time here because you haven’t vaccinated. But then you may get a BVD outbreak.
Best Case Scenario:
You don’t have an outbreak
You have an outbreak.
Some cows still get sick. ~6% of your cows abort calves
Best Case Scenario: You don’t have an outbreak
Average Case: 20% of your cows abort calves
Worst Case Scenario: 59% abort
None of your cows abort due to BVD
18 head of your cows abort due to BVD
None of your cows abort due to BVD
60 head of your cows abort due to BVD
177 head of your cows abort due to BVD
You haven’t lost anything
Your fross loss is $23,400 or $78/head
You haven’t lost anything
Your fross loss is $78,000 or $260/head
Your fross loss is $230,100 or $767/head
You haven’t lost anything
There’s a net loss of $1,071 or $4/head
You haven’t lost anything
There’s a net loss of $3,570 or $12/head
There’s a net loss of $10,532 or $35/head
Your vaccine investment is $1,209 or $4/head
Total loss: $25,680 or $86/head
Remember: BVD virus is widespread and most herds are at risk for infection.
Total loss: $81,570 or $272/head
Total loss: $240,632 or $802/head
