Recently, researchers have found that the vaccination for whooping cough which was introduced in 1999 is less effective as the cases of whooping cough has yet again begin to whelm up. A study has found that children vaccinated with the 1999’s drug were at higher risk of being affected the disease in 2009 and 2011. The findings of the study have been published in the journal, American Medical Association.

It has come to light that in past few years, the cases of whooping cough in Australia have multiplied. The lead researcher of the study Prof. Stephen Lambert informed, “The vaccination still offers the best protection against developing whooping cough - infants who aren't vaccinated have a much greater risk of contracting the disease and developing serious complications”.

Whooping cough can be a fatal disease for the infants. Parents are advised to get their children vaccinated at an early age so that the aftermath of the disease could be prevented. Further studies are required to be conducted so that an effective cure of the disease could be found. It is hoped that the recent findings would help researchers in preparing an effective drug for whooping cough.
