Researchers for disease control and prevention researchers say that the vaccine used for whooping cough is less effective because the bacteria behind the disease have mutated. The researchers analyzed laboratory samples from whooping cough patients between 2000 and 2013 and found that Bordetella pertussis, which causes whooping cough, has undergone genetic changes over time.
Researchers who published their data this week in the journal "Emerging Infectious Diseases" want to change it.
"The genomic data we provide will support open research toward improved vaccine development and disease control strategies," writes CDC authors.
At present, children are less protected by the modern vaccine.
Dr. William Schaffner, Professor of Prevention Medicine at Vanderbilt University Medical Center, told NBC News that "the pertussis vaccine is not optimal".
"We make the best use of the vaccine, while we" are frantically doing research to do a better one, "Schaffner said, adding a new vaccine is far from ready.
Multiple States School Breakdown
Some states have reported whooping cough outbreaks in severe schools over the past two months. Among them:
Whooping Host: What You Need to Know

Jumping cough is The respiratory infection looks like a typical cold with a runny nose and low-quality fever.The rash with the "whoop" sound of any infected gasping for air will not appear until two weeks later, according to CDC But the cough likes to stick and can stay for weeks. Then it got the nickname – "cough 100 days".
How it spreads:
This disease is highly contagious, spreads when someone coughs, sneezes or talks and infected droplets are injected into the air, others inhaling and infecting them.
Doctors treat whooping cough with antibiotics and the CDC strains 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 a decade.
Babies with Highest Risk

Of the more than 13,400 cases reported in 2018, there were 10 pertussis deaths, according to CDC.
Of these, four of them were children under the age of 1.
The children face the greatest risk of complications and about half of the children younger than 1 year are in hospital, often because they have trouble breathing, the CDC reports. The quarter develops pneumonia. One in 100 will die .
