Whooping Cough Mutated Strain Immune to Vaccines

Vaccines Are Mutating Virus

 The bacteria that causes whooping cough has mutated, eroding the protection provided by the vaccine now given to children, scientists warned yesterday. University of NSW researchers have identified significant changes in the two most common strains of the bordetella pertussis bacteria, which they also traced back to events in the late 1990s. They found while the vaccine now in use was effective against some of the strains circulating in Australia it may no longer protect against two strains, known as MT27 and MT70.
