New School Immunization Law for Students Entering 7th Grade

A new California state law requires all students entering 7th grade each year to provide proof of having immunization against pertussis before starting school. 

A single dose of pertussis vaccine booster (‘Tdap’) will meet the requirement. Tdap safely protects against 3 dangerous diseases: tetanus, diphtheria, and pertussis. Pertussis (whooping cough) is a highly contagious bacterial illness spread by coughs and sneezes. Children sick with pertussis have severe coughing attacks that can last for months. Parents should be aware that the protection from childhood immunization to pertussis wears off, and adolescents may be at risk for infection without a booster.

Don't wait, get your adolescent vaccinated today!
