Background: The robustness and persistence of vaccine antigen-induced antibodies are often used as proxy indicators of vaccine efficacy, but immune responses to vaccine vectors are typically less well-defined. Our study considered the kinetics of immunoglobulin (IgG) responses against the vector (vesicular stomatitis Indiana virus [VSIV]) nucleoprotein (N) and the inserted antigen (Ebola virus [EBOV]) glycoprotein (GP1,2) components of the rVSVΔG-ZEBOV-GP (rVSV-ZEBOV) vaccine and evaluated their use as biomarkers to confirm self-reported vaccination status.
Methods: From the Partnership for Research on Ebola Virus in Liberia (PREVAIL) I clinical trial (NCT02344407), we randomly selected 212 participants who received rVSV-ZEBOV (n=107) or placebo (n=105).
Purpose: To characterize corneal and conjunctival abnormalities (CCAs) and their impact on visual acuity in a cohort of survivors from the Western African Ebola virus disease (EVD) outbreak.
Design: A post hoc analysis of 121 patients, who had previously undergone screening for the Ebola Virus Persistence in Ocular Tissues and Fluids study, was performed.
Methods: Patients underwent a comprehensive ophthalmic exam at the Lowell and Ruth Gess Eye Hospital in Freetown, Sierra Leone.

Background/objectives: Ebola virus disease (EVD) survivors develop post-acute ophthalmic sequelae, including a high prevalence of uveitis that may be complicated by vision-threatening cataract. After the non-detection of Ebola virus (EBOV) RNA in sampled ocular fluid, vision impairment due to cataract can be treated safely and effectively via manual small incision cataract surgery (MSICS). However, the long-term ocular visual outcomes and assessment of ocular tissues, including for genomic RNA, have been infrequently or not reported in Western African survivors.

Introduction: Substernal extravascular defibrillators (EV ICDs) have been shown to be effective and safe for patients at risk of sudden cardiac death, however, there is little evidence around the safety of extracting chronic devices.
Methods And Results: We present a 50-year-old patient in whom a Medtronic EV ICD system was successfully removed without specialist extraction tools, 186 weeks after implantation, by an operator experienced in transvenous lead extraction but without formal training in EVICD implantation.
Conclusion: The successful extraction of an EV ICD system is possible without specialised tools at least 3.
