I acquired most of my stock as bred heifers. They came as vaccinated, wormed, etc. I have asked specifically if that includes the TT and the producer said yes. I have witnessed the vaccination in a few cases. I am going into the fourth year with this stock. I have continued to vaccinate them in accordance with my protocols which are at a minimum based on the literature with the vaccines.
With that background, here is my tetanus question. A bred heifer comes in vaccinated. But let us say she only got one dose at her initial exposure. Or second, let us say they omitted the TT vaccination. I have boostered her each year with 1 mL of TT via intramuscular injection. If her first exposure was one dose/no dose or the 2 doses were not 30 days apart like most TT vaccines require, would she now have a protective level of immunity based on the annual vaccinations?
