Whooping cough is particularly dangerous for babies less than six months of age. They are affected more seriously by the disease than older children or adults, and are more likely to develop complications.
One in every 200 babies who contract whooping cough will die.
Measles is an acute, highly infectious illness caused by the measles virus. Measles can cause serious complications such as pneumonia (lung infection) and encephalitis (inflammation of the brain). It may also cause middle ear infection.
Measles should not be regarded as a simple mild disease. Deaths occur mainly in children under five years of age, primarily from pneumonia, and occasionally from encephalitis. Complications are more common and more severe in people with a chronic illness and very young children.
This is not a suggestion - this is happening in NSW High School now.
Boys receive this vaccine in year 7 / 8 because they can be carriers of this virus.
