I was in a farm supply yesterday looking for Spirovac VL5 or L5. It is produced by Zoetis. I got 2 bred heifers I bought at the Kentucky Simmental Sale a month or so ago. When I vaccinated this week, I used Titanium FP 5 L5 HB. I was afraid to use it on the heifers because I don't know their vaccination history. They may have never been exposed to a MLV Fetal Protection vaccine and the IBR component can cause abortions in cattle not previously exposed to MLV FP in the last 12 months. All my cattle have so no issue there.
I looked through the vaccine case and there was no vaccine for Leptospira that covered Leptospira borgpetersenii or the more common designation Hardjo bovis as abbreviated HB. They had Leptoferm. They had Bovi Shild Gold FP 5 L5, etc.
I mentioned this to their vaccine guy and he said "Oh yes, Leptoferm covers Hardjo." I said yes, "It covers the Species Leptospira hardjo but not the Hardjo bovis serovar". We discussed it for 20 minutes and it was clear that he thought any vaccine that had the word "hardjo" on it covered all the strains.
Leptoferm and Spirovac are both Leptospira vaccines. Both made by Zoetis. But only Spirovac covers Hardjo bovis (Leptospira borgpetersenii). Leptoferm does not.
I showed this to him on my cell phone by looking up the manufacturer's brochure for Spirovac. He had no idea they were different.
In the case of Spirovac, it does not have HB in the name for the vaccine but it does cover HB. Most other vaccines use the "HB" to indicate it covers Hardjo bovis (Leptospira borgpetersenii). For example, all the Bovi Shield Gold products that cover HB use HB at the end of the title. Titanium 5 L5 does, it is listed as Titanium 5 L5 HB.
You just got to wonder how many producers are getting bad information.
