OK, so it's a Friday before a holiday - what better time to bring up some more vaccine controversy? 
From my June 2010 issue of Pediatric News:
Parents' concern that children receive too many vaccines too soon can result in delay or avoidance of vaccination, with the measles-mumps-rubella vaccine often being delayed. However, a recent study showed no neurologic harm from on-time receipt of all the recommended vaccines - including the MMR - from the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices (ACIP), and children with on-time receipt of vaccines performed better on select neurologic testing than those delaying vaccine.
The study by Dr. Michael J. Smith and Dr. Charles R. Woods of the University of Louisville (Ky.) addressed the "too many vaccines too close together" issue. Using publicly available Vaccine Safety Datalink data from a previous study on thimerosal exposure and neuropsychological outcomes, the authors found that getting all recommended vaccines per the ACIP recommended schedule was associated with better - not worse - performance on selected neurologic outcomes at 7 - 10 years, even when such factors as socioeconomic status were controlled for (Pediatrics 2010;125:1134-41.). Importantly, there were no statistically significant differences favoring the less-vaccinated children. The authors concluded that these data add reassurance for parents who are concerned that their children receive too many vaccines too soon.
-------------------------------------------------------------------
In addition, there is evidence that the MMR may need to be given even earlier than the 12 - 15 month time frame.
While waning maternally endowed antibody by 6 months of age is expected for most infections, we now have evidence of even younger age for disapperance of the vaccine-interfering yet protective antibody to measles.
Maternally endowed measles antibody disappeared at a median of 3.8 months in infants of previously measles-infected mothers, and at 1 month of age in infants of vaccinated women. Thus, infants became vulnerable to measles even earlier than previously reported.

You beat me to it!!!
