Vaccination is the best way to protect against diphtheria, tetanus, and perlussis.
Because most children get the vaccines, there are now many fewer cases of these diseases. There would be many more cases if we stopped vaccinating chil- dren. Most children should have a total of 5 DTP vaccines. Like DTP, it prevents diphtheria, tetanus, cold pertussis. It is only given for the Pith and 5th doses.
