Hey Fiona,
I'm so glad the dots are getting more connected. And it's huge that you're standing strong with 'Vitamin N' (NO!) when you see fit.
But, did you know that low/falling titers ≠ [do NOT equal] a lapse in immunity?
If that's news (and it is to many, so you'd not be alone), please check out this post that explains why yearly titers is a waste of time and money (and worse, can become a mistaken urge to vaccinate again).
