Researchers at the Center for Disease Control and Prevention say vaccine against whooping cough is less effective because the bacteria behind the disease have mutated less effectively. The researchers analyzed laboratory samples of patients with whooping cough between 2000 and 2013 and found that Bordetella pertussis, which causes whooping cough, has undergone genetic changes over time.
Scientists who have published their data this week in the journal [Emerging Infectious] Diseases "want to change that.
" The genomic data we provide will support open research to develop vaccines and the CDC authors write.
Currently, children are less protected by the modern vaccine.
Dr William Schaffner, Professor of Preventive Medicine at Vanderbilt University Medical Center, told NBC News "The pertussis vaccine is not optimal."
"We use the vaccine as best as we can" "We were desperately looking to make a better one," said Schaffner, adding that adding a new vaccine is far from over Finished.
School Breakouts in Several States

Whooping Cough: What You Need to Know
Normally you do not know that a child has whooping cough because it starts with a runny nose and looks like a typical cold. (Photo: Getty Images)
Whooping cough is a show-off. The respiratory tract infection looks like a typical cold with a runny nose and low fever. The fierce coughing with the "Whoop" sound of an air-filled will only appear two weeks later, according to CDC . But the cough stays happy and can take weeks. So the nickname was earned – the "cough of 100 days".
As it spreads:
This disease is very contagious. It spreads when someone coughs, sneezes or talks and sprays infected droplets into the air where other people inhale and infect them.
Doctors treat whooping cough with antibiotics, and the CDC emphasizes that early treatment is important so it is less serious.
The best protection against whooping cough remains the DTaP vaccine, which also protects against diphtheria and tetanus for ten years.

Of the more than 13,400 cases reported in 2018, ten deaths occurred after the CDC  because of Pertussis' age of one year.
Babies are at greatest risk for complications, and about half of babies younger than 1 are hospitalized, often because of respiratory problems, the CDC reports. A quarter develops pneumonia. One in 100 will die .
