Hi Elizabeth,
The current understanding is that any titer, high or low, shows protection has been established. While there's certainly no harm in giving regular doses of transfer factor (I take it daily and have lots of my patients on it), if your goal is furthering parvo immunity, you'll want to read this week's latest blog post. Planned exposure with transfer factor in the body would be an even more efficacious immunization plan than what my colleague described and I blogged about. Then, you've got the immune system of your pup on "high alert" while exposure happens, so the resulting immunity should be very well tuned and balanced.
