Abstract excerpt
In Japan, the Bordetella pertussis strain Tohama provided by the National Institute of Health, Japan has been used for the production of acellular pertussis (aP) vaccines since 1981. In the present study, in order to verify the genetic consistency of B. pertussis vaccine seed strains, we analyzed the genetic properties of the working seeds obtained from five Japanese vaccine manufacturers, and compared them with...
