Answer to the CDC: Validation Must Precede Promotion

International audience; We would like to thank the CDC colleagues for their Commentary in what constitutes the first comment on a paper published in the Annals in decades. We view critique as a strength of scientific exploration. The Commentary concludes with as statement agreeing with the findings and conclusions of our paper: “we recognize CDC SVI may not identify the most vulnerable populations in all applications and has not done so in the Rufat et al. study (…) we agree with the authors.”
