Are people who are against, or delaying, vaccinations against even the rubella one? I will never forget my panic when I found out that I had been tutoring a student who, a day or two later, came down with Rubella. I was about a month pregnant at the time. My mother thought she remembered that I had had the "German measles" but I couldn't relax until my child was born, and everything was okay.
It takes a community to protect a child.
