I was just at the pediatrician and she said that immunity is pretty well boosted by about 24 hours after the vaccine.

maybe for most other vaccines. I am not sure if she based her opinion on that general assumption. I find--working as a researcher in the vaccine area--that alot of the Drs aren't up-to-date on the latest info. CDC and other health orgs...state partial immmunity after 2 weeks for kids with approaching full immunity around 5 weeks (1 week after booster).

Here is a NEJM article. The reasearchers didn't measure until 21 days after, but a hemagglutination-inhibition titer of 1:40 or more (i.e., immunity) was achieved by day 21 in 74.5% of subjects between 3 and 11 years of age, after a second dose, at day 35, the titer had been achieved in 98.1%.
