[Assessment of postvaccinal response in children past pertussis]

Abstract

In the nineties, despite high percentage of vaccination of children, from 86% to 99% dependently on the region, there came to the increase of whooping cough cases. Until then infants and children to the age of 5 years suffered from this disease, whereas in the last decade the number of cases increased mainly among children over 5 years of age, who were subjected to full cycle of vaccination against whooping cough. Searching for the causes of such epidemiologic situation the following suggestions have been given: change of the bacteria antigenicity, the phenomenon of postvaccinal immunity extinction, immune system mechanisms disorders and groundless excuse from vaccination. The study estimates parameters of postvaccinal response to immunization with selected vaccines in children post whooping cough.
