Well, if you think your kids don't need to be vaccinated against whooping cough, a new study could change your mind. Our senior medical correspondent Elizabeth Cohen explains.</s>ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: A new study looks at what happens when parents decide not to get their children vaccinated for whooping cough, also called pertussis. Let's take a look at the results. They found that among these children who were vaccinated, they had a 1 in 500 chance of getting whooping cough. But among the children who were not vaccinated, 1 in 20 of them got whooping cough. Now, whooping cough is not some little disease. It can go on for months and months. Children often feel terrible, and there could be some serious repercussions. Let's take a look at what some of those are. People who have whooping cough sometimes get these complications: pneumonia, seizures and brain damage. Now, some children, not a large group, but some babies do sometimes die of the disease. So, what's a parent to do? Well, according to the American Academy of Pediatrics and others, they say get your child vaccinated for whooping cough. The vaccinations go in this order. It is five doses between the ages of two months and kindergarten. And also, children and adults are supposed to get boosters every 10 years.
