I'd give it anyhow. I've had that happen before, oops! I've even seen recommendations of two weeks, which I think is too short, but better than nothing. I'd just make sure that doe's babies get plenty of colostrum.
Keep in mind that no antibodies cross the placenta. The babies get their passive immunity from antibodies in colostrum. If the doe was previously vaccinated, the re-vaccination prior to kidding just jump starts her system to increase the levels.
