How do vaccines effect pregnant women?

Some of the questions raised by the topic of vaccines are should they be required for kids before entering school. How do vaccines effect pregnant women? Do vaccines cause health problems? What drugs added to vaccine cause health problems? These are a few questions that should be answered in the paper. MY POSITION STANCE IS THAT VACCINES SHOULD NOT BE A REQUIREMENT because of the problems it may cause. Vaccines can cause health problems such as autism. Would like the writer to also mention Dr. Jill Stein, became known for her opposition to vaccines for kids even though she was a pediatrician.
