Abstract Large-scale deployment of safe and durably effective vaccines can curtail the COVID-19 pandemic.1−3 However, the high vaccine efficacy (VE) reported by ongoing phase 3 placebo-controlled clinical trials is based on a median follow-up time of only about two months4−5 and thus does not pertain to long-term efficacy. To evaluate the duration of pro- tection while allowing trial participants timely access to efficacious vaccine, investigators can sequentially cross participants over from the placebo arm to the vaccine arm according to priority groups. Here, we show how to estimate potentially time-varying placebo-controlled VE in this type of staggered vaccination of participants. In addition, we compare the per- formance of blinded and unblinded crossover designs in estimating long-term VE.

Backgroud The long-term outcomes of this combined procedure remain elusive. This meta-analysis aimed to assess the long-term efficacy and safety of combined procedure. Methods PubMed, Embase, Cochrane Library, and Web of Science were systematically searched from the establishment of databases to 1 January 2021. Studies on the long-term (defined as a mean follow-up of approximately 12 months or longer) efficacy and safety outcomes of combined ablation and LAAC were included for meta-analysis. Results A total of 16 studies comprising 1,428 patients were included in the meta-analysis. The pooled long term freedom rate from atrial arrhythmia was 0.66 (95% confidence interval [CI], 0.59-0.71), long-term successful rate sealing of LAAC was 1.00 (95% CI, 1.00-1.00), and ischemic stroke/transient ischemic attack/systemic embolism during follow-up was 0.01 (95% CI, 0.00-0.02). Meanwhile, the rates of peri-procedural adverse events included phrenic nerve palsy, intracoronary air embolus, device embolization, peri-procedural death of 0.00 (95% CI, 0.00-0.00), procedure-related bleeding events of 0.03 (95% CI, 0.02-0.04), and pericardial effusion requiring or not requiring intervention of 0.00 (95% CI, 0.00-0.01). Moreover, the rates of long-term adverse events rate included device dislocation, intracranial bleeding, and pericardial effusion requiring or not requiring intervention, and all-cause mortality of 0.00 (95% CI, 0.00-0.00), device embolization of 0.01 (95% CI, 0.00-0.01), and other bleeding events of 0.01 (95% CI, 0.00-0.03). Conclusion This meta-analysis suggests that the strategy of combined atrial ablation and LAAC is effective and safe during long-term follow-up
