AI-Summary

What this Trial Is About

The purpose of this study is to continue evaluating how well the RSV vaccines work as they are currently being used in routine clinical practice. Some of the questions that the investigators hope to answer with this study are: 1) What is the overall effectiveness of these vaccines? 2) How long does immunity last? 3) How effective are the vaccines against new strains? 3) Does the vaccine's effectiveness vary by age?
