A team of Australian scientists at the University of New South Wales have published a study that the bacteria for Whooping Cough has developed new strains. The study was published in the journal Emerging Infectious Diseases in which scientists show that two of the most common strains of the bacteria, Bordetella Pertussis have mutated significantly.
 
Scientists are finding that the vaccination against Whooping Cough are therefore not the most effective. However due to the potential deadliness of this disease for infants, getting vaccinated is still a good idea.
 
According to the Centers for Disease Control Whooping Cough infections can be potentially deadly for babies who are eight weeks or younger. They also report that more than half of these babies get their infection from their parents who may have contracted Whooping Cough which is an upper respiratory infection. Therefore anyone caring for an infant should get themselves a booster shot to protect themselves against developing Whooping Cough.
