CD4 and COVID-19: Of note, in the hybrid immunity group, we found numerically higher, but not statistically significant higher rates of COVID-19 endpoints among PLWH with CD4 counts <350 cells/μl compared to ≥350 cells/μl (HR 1.43; 95% CI 0.93–2.19; p = 0.107), and statistically significant higher rates among PLWH with HIV viraemia compared to those with viral suppression (HR 1.8; 95% CI 1.27–2.56; p = 0.001) (Fig. S34).
