Potential residual confounders in an analysis of lifestyle factors and risk of incident systemic lupus erythematosus: comment on the article by Choi et al

Abstract

booster vaccination (11). Our report demonstrates the possibility of achieving humoral immunity against SARS-CoV-2 after initial failure through the use of a cross-platform booster vaccination strategy. Prior research has demonstrated that heterologous vaccination strategies may induce a more robust immune response in healthy adults (12-14). We believe future research is needed to establish relevant antibody reference values to identify patients without adequate protection against COVID-19 infection, and to understand the role of cross-platform booster vaccination when primary mRNA vaccination and/or booster vaccination fails to induce a sufficient immune response.
