Harvard-Westlake students were vaccinated. Competitors fought the whooping cough anyway



Under California law, children must get all their doses of the whooping cough vaccine to be allowed to attend school, unless they have a medical reason for not being vaccinated. By the time they reach 6 years of age, most of the children received five doses of the diplogen-tetanus-acellular-pertussis vaccine, or DTaP. They must then get a booster before entering the seventh grade.
