Background and Objectives: The Haemophilus influenzae (Hib) conjugate vaccine (HibCV) using a pentavalent formulation was introduced to the Iranian routine immunization program from November 2014. Iran is preparing to include Pneumococcal conjugate vaccines (PCV), as well. Measuring and monitoring the impact of HibCV and PCV are necessary to provide evidence for introduction and sustained administration of this vaccine.

Methods: We addressed the possibility of implementing the "3-tiered approach to IB VPD surveillance" as proposed by the World Health Organization using a feasibility study. Expert opinions were asked to address published literature regarding the study design and methods of measuring the impact of newly introduced vaccines.

Results: There are different methods and study designs to measure the impact of new vaccines, including population based active surveillance systems and vaccine effectiveness studies. The results of the feasibility study and expert opinions highlighted the superiority of a sentinel hospital-based surveillance system in Iran.

Conclusion: It is necessary to conduct some systematic reviews and meta-analyses to provide evidence for the trend of Hib and Streptococcus pneumonia related diseases, i.e. invasive bacterial diseases including meningitis, pneumonia, and sepsis. To monitor indirect effects of the PCV vaccine, implementing periodic surveys on the prevalence of nasopharyngeal carriers are recommended.
