In brief: About 4 weeks

The booster is actually only designed to catch the roughly 5% of "non responders" to 1st dose of mmr.
The 2nd MMR dose though may enhance MMR immune titers as well. Studies in those getting first dose show variation in how quick they mount response based on age & possibly genetics, whether breastfeeding, etc. For older infant: response rates: 85-90 % 4 weeks 81% 3 weeks 61% 2 weeks 2% 1 week.
