Brief Summary

The aim of vaccination is to protect the patient against disease by stimulating his immune system. DTPolio is a tetravalent vaccine providing protection against pertussis, diphtheria, tetanus and polio. In France, the vaccination schedule sets the vaccination recommendations applicable to people according to their age. In this schedule, a booster of DTPolio at the age of 25 is recommended. The vaccination coverage for patients over 16 years of age is insufficient in France.
