Previous Version of the Whooping Cough Vaccine More Efficient

According to Australian researchers, the former version of the whooping cough vaccine was better at protecting patients against the condition than the newest version. The data experts used were collected during a 3-year epidemic, and then 9 years later.

Scientists mostly focused their attention on small children. The old version of the vaccine was found to be more likely to protect the young ones from catching the disease before they turned 12 than the newer version, LiveScience reports.

The new finding is in tune with previous studies, which suggest that acellular pertussis vaccine (the latest version) has only medium-term protective effects, which wane after a few years.

As scientists are working on creating a new vaccine against whooping cough, their main objective will be to create a mixture that can provide many years of protection without causing any adverse side effects.
