As students return to middle schools and high schools in California this fall, they will need more than fresh notebooks and apples for their teachers. Thanks to a state law that took effect last month, students entering grades 7 through 12 will need proof that they received a vaccine for whooping cough. The law was prompted by last year's outbreak of the highly contagious respiratory infection, which is also known as pertussis. Nearly 9,500 cases were reported in California, the most in 65 years, according to the Centers for Disease Control and Prevention.
