STAUNTON, Va. (WHSV) -- A new study in the journal "Pediatrics" showed that when more kids get vaccinated, fewer infants are getting whooping cough.
In the last few years, Dr. Doug Larsen, with the health department, said there was an all-time high of whooping cough cases in the Shenandoah Valley and surrounding area.
Last year there were 84 cases, but this year though they've only had 11.
Babies are more vulnerable because they can't be vaccinated until they are six-months-old.
Larsen said no matter your age, it's important to be vaccinated.
"We're trying to get a cocoon around the baby of everyone who's going to be taking care of the child to have vaccination and that does include if they have siblings in the sixth grade of thereabouts," said Larsen.
Larsen said kids are getting vaccinated too.
In Staunton, 94 percent of kids in 6th grade received the vaccination for whooping cough.
He said often times, older adults who haven't had the vaccine in a long time could be carrying the bacteria in their body.
