A
Activated and inactivated tetanus and diphtheria toxins
💡 Explanation:
DPT consists of inactivated diphtheria toxin known as toxoid, destroys whooping cough microbes and inactivated tetanus toxin known as toxoid. Each of these is obtainable individually or tetanus diphtheria immunisation may be mixed up without whooping cough, then it is known as DT (double toxoid). Usually DPT is applied in 3 doses at the interval of every month starting at the age of 6 weeks.
