Resumo(s)
Background: The test-negative design (TND) has been used to monitor influenza
vaccine effectiveness (IVE).
Negative controls are those that tested negative for any influenza virus -
however, there are issues related to the selection of the negative controls;
As it is hypothesized a potential bias introduced by virus interference in
TND, some authors suggest to use other respiratory virus as control
group.
Hence, the objective of this study is to compare IVE estimates using the
classic TND and alternative controls.
