Influenza Vaccine-Averted Illness in Chile, Guyana, and Paraguay During 2013-2018: A Standardized Approach to Assess the Value of Vaccination.

ABSTRACT:

Background

To better establish the value of vaccination against influenza viruses, we estimated vaccine-averted influenza illnesses among young children and older adults in Chile, Guyana, and Paraguay.

Methods

We gathered country- and target population-specific data on monthly influenza hospitalizations, vaccine coverage, and vaccine effectiveness from surveillance records and immunization registries during 2013-2018. We applied a static compartmental model to estimate differences in the number influenza-associated respiratory disease events (symptomatic nonhospitalized illnesses, medically attended illnesses, hospitalizations) in the presence and absence of influenza vaccination programs.

Results

Between 2013 and 2018, vaccinating 68% of children aged 6-23 months in
