[Effects of the immunization program in Vojvodina].
BACKGROUND
With the widespread use of active immunization, significant results have been achieved in the control and prevention of numerous communicable diseases. The Expanded Programme on Immunization of the World Health Organization is intended to strengthen national programs for the reduction in the incidence and mortality rates and global elimination or eradication of communicable diseases. The aim of this paper is to analyze results of the immunization program in Vojvodina. MATERIAL DND METHODS: The results of the immunization program were analyzed on the basis of the incidence rates, since the introduction of the mandatory reporting system, till 2006. The analysis included immunization coverage against diphtheria, tetanus, pertussis, poliomyelitis and measles as well as reported cases of missed opportunities in the period from 1997 to 2006.


RESULTS
Poliomyelitis has not been reported in Vojvodina since 1963, diphtheria since 1978 and measles in the period from 2001 to 2006. Sporadic cases of pertussis have been reported in unimmunized children of the youngest age, and tetanus in unimmunized elderly population. Vaccination coverage against poliomyelitis, diphtheria, tetanus and pertussis was above 96%. Vaccination coverage against measles was lower (95% vaccination, 87% revaccination). The highest proportion of missed opportunities was caused by not responding to immunization calls (46.6%).


CONCLUSIONS
These results can be maintained by up-to-date (UTD) immunization and high vaccination coverage without territorial and population differences. Data on the total number of children without up-to-date vaccination cannot be obtained on the basis of administrative coverage follow-up. It is necessary to establish follow-up mechanisms for UTD immunization, which would reveal the number of children at risk from vaccine preventable diseases and characteristics of unimmunized population.
