Anyone have any helpful info on effectiveness and immunity in general relating to spacing doses differently than recommended? I guess I'm confused about whether the immunity to the diseases are less effective with fewer, more spaced out doses, or if the only difference is in how long the immunity will actually last.
I was not vaxing until age one, then gave DD2 the Pentacel shot at 1 year and 2 months, (DTaP, Polio, Hib). I then decided to hold off and learn more about selective and delayed vaxing before giving her any other doses. Closing in on one year later, she is super strong and healthy and aside from a couple minor colds she's never been sick, but now that she's 2 and has a stronger system, I am thinking about a second dose of the Pentacel and eventually MMR. She might start going to daycare now too.
Here's where I'm stuck: The recommended second dose for the Pentacel was after 2 months, and it's been almost 12 months, so if I give her a second dose of the same vaccine now will it be "increasing" her immunity or just "renewing" it? Does this depend on the disease? Did I drop the ball by not following the recommended spacing and now we would be pretty much starting fresh? Any info or links would be tremendous help. Thanks!
