A review, to be published in the Journal of the American Medical Association (JAMA), of a new vaccine offered for whooping cough cases has been asserting that it is less effective as compared to a vaccine that was previously being described.

The study was conducted by a collaboration of researchers from the Queensland Children's Medical Research Institute and Brisbane Royal Children's Hospital. It has shed light on the fact that the new vaccine was causing a relapse of the illness.

As per the findings, the review was decided to be carried out after it was known that younger children treated in recent past years were having a recurrence of the deadly disease. Whooping cough starts with simple coughing, the team has told in the meanwhile, which mainly targets young children and infants.

Though early diagnosis or vaccine available for the same can prevent the disease, it is being said that negligence can lead the illness to noisy coughing, sometimes leading to fatal consequences.

However, a cellular vaccine was brought into front in 1998, manufactured from a few parts of the pertussis bug, which was certainly more effective. But, its replacement with a new vaccine showed negative results.

Thus, suggestions are being made that stress should be on developing a much stronger vaccine than the one currently prescribed.
