Probably not: If you received MMR vaccine once (which was a standard practice back then), the antibody level is not expected high enough to provide a full protection.

The basics: One dose of measles vaccine was the common during the 60's & data showed about 75-85% would gain protective levels of antibody. By the early 1990's sporadic measles outbreaks on college campuses led to the 2 dose program we use now that brings protective levels to 90%+ of recipients. Given the influx of never vaccinated aliens & vaccine avoiders now in the population another dose would be wise.
