It has been seen that ,parents go for tetanus toxoid vaccine,after every and any type of injury to the child.This is a wrong practice,as it may blunt the effect of previous vaccines ,if the child has received 3 doses of primary vaccination in first year of life and booster at age of 18 months,5 years and 10 years of age.If the child has received vaccine properly at scheduled periods,the vaccine will protect the child against tetanus after minor injuries,without taking any extra vaccine after injury.Child may require extra vaccine in some situations,which will be decided by the doctor.For example if 10 years has lapsed after last dose,then the child may be given extra dose even after minor injury,otherwise no extra dose is required after minor injury.In cases of major and lacerated injury,the child may require extra dose if 5 years has lapsed after the last dose.The national immunisation schedule has been prepared to immunise the child against tetanus,as it is presumed that,the child may face multiple minor injuries during the childhood period.
