This is why I am having a difficult time with you. I am not misinformed. This is for public schools. Read for yourself. From the CDC themselves: School immunization laws
Each state has immunization requirements, sometimes called "school laws," that must be met before a child may enter school. These may include vaccination against diphtheria, pertussis (whooping cough), tetanus (lockjaw), Haemophilus influenzae type b, measles, mumps, rubella, polio, and hepatitis B. Some states have added varicella (chicken pox) vaccination to the list of required vaccines. Smallpox vaccination was once required, but the disease has been so successfully eradicated that this vaccination is no longer needed.
In most states, a parent must bring written proof of a child's immunizations from the health provider or clinic at the time of school registration. If a required vaccination has not been obtained, and there is no health condition or religious objection preventing immunization, the child must receive the vaccinations before school entry. You can find out what the requirements are in your state through a link provided at the end of this section.
These required vaccinations don't just protect the children in a classroom. They protect the teachers, parent volunteers, visiting grandparents, and everyone else who enters the classroom or provides services to the school. The blanket of protection provided by rubella ("German measles") vaccination is especially important for women who are pregnant. Rubella can cause serious effects on the developing fetus, including deafness, blindness, heart disease, brain damage, or other serious problems, including miscarriage.(9) Today's middle-aged adults may remember how common this disease was before the rubella vaccine became available. Rubella was feared for its effects, including ear infection, pneumonia, diarrhea, seizures, brain damage, and death.(10)
