Diphtheria, acellular Pertussis and Tetanus vaccine

Japan. The acellular or component pertussis vaccine have been few
side effects(Encephalopathy, fever, swelling of injection site ---- )
compare to that of whole cells vaccine.

The delay of introduction to other countries, was that it was difficult
to do the clinical vaccine control-study, since the prevalence of
whooping cough was low in Japan. Therefore, USA, Canada and
European countries independently conducted the control study of
this acellular pertussis vaccine and later proved its efficacy.

What is pertussis(whooping cough) ?
