Impact of the COVID-19 pandemic on influenza vaccination coverage in Latin America: Southern Cone, Argentina, Chile, and Uruguay

The studied countries have observed a decrease in post-COVID-19 influenza vaccination coverage. Therefore, they are working to achieve optimal coverage, not only in influenza risk groups but across the entire population. Data on influenza vaccination coverage are limited in some cases. The availability of new vaccines can provide greater immunogenicity, efficacy, and effectiveness. However, they represent a challenge for the Expanded Program on Immunization, which requires cost-effectiveness studies to evaluate new vaccines while experiencing restricted national budgets.
