Risk of all-cause and cardiac-related mortality after vaccination against COVID-19: A meta-analysis of self-controlled case series studies
Abstract
Statement of Retraction We, the Editor and Publisher of Human Vaccines & Immunotherapeutics, have retracted the following article: Marchand, G., Masoud, A. T., & Medi, S. (2023). Risk of all-cause and cardiac-related mortality after vaccination against COVID-19: A meta-analysis of self-controlled case series studies. Human Vaccines & Immunotherapeutics, 19(2). https://doi.org/10.1080/21645515.2023.2230828 After publication, concerns were raised regarding the methodology and the integrity of the data reported in the article. When approached for an explanation, the authors have provided a full response to the queries raised. However, after assessment by an editorial board member, the Editor and Publishers have determined that the validity of the findings remains in question due to these data and methodology concerns. In addition, after publication, a major dataset that formed a central part of the evidence presented in the paper has been removed from public access by the issuing government authority; therefore, key portions of the published analysis are unverifiable using publicly available data. As verifying the validity of published work is core to the integrity of the scholarly record, we are, therefore, retracting the article. The corresponding author listed in this publication has been informed. The Editor and Publisher confirm that there is no allegation of research misconduct on the part of the authors. We have been informed in our decision-making by our editorial…
