You and Jeri both bring up the same good point, Lorraine: many vets understanding of immunology is shaky, too. Especially those who continue to revaccinate throughout an animal's life, but also, as you point out, the whole titer issue.
As I look back over my vet school experience, I really had no clue how damaging vaccination could be. Nor did I learn about long term immunity, and no one discouraged repeated vaccinations, certainly.
Thanks for this. Right on.
