The “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” is the third member of human (CoV) that held accountable for current “coronavirus disease 2019 (COVID-19)” pandemic. In past two decades, world has witnessed emergence other similar CoVs, namely SARS-CoV in 2002 and MERS-CoV 2013. extent spread these earlier versions was relatively low comparison to SARS-CoV-2. Despite having numerous reports inclined towards zoonotic origin virus, one cannot simply sideline fact no animal originated CoV thus far identified considered initial edition SARS-CoV-2; however, under-sampling diverse variety coronaviruses remains a concern. Vaccines are proved be an effective tool bringing end such devastating Many vaccine platforms explored same but this review paper, we will discuss potential replicating viral vectors as carriers

Zoonotic viruses continually pose a pandemic threat. Infection of humans with for which we typically have little or no prior immunity can result in epidemics high morbidity and mortality. These public health economic impact exacerbate civil unrest political instability. Changes human behavior the past few decades-increased global travel, farming intensification, exotic animal trade, warming on migratory patterns, habitats, ecosystems-contribute to increased frequency cross-species transmission events. Investing pre-clinical advancement vaccine candidates against diverse emerging viral threats is crucial preparedness. Replication-defective adenoviral (Ad) vectors demonstrated their utility as an outbreak-responsive platform during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Ad are easy engineer; amenable rapid, inexpensive manufacturing; relatively safe immunogenic humans; and, importantly, do not require specialized cold-chain storage, making them ideal equitable distribution stockpiling.

Introduction: To date, almost 7 billion doses of the different types vaccine against SARS-CoV-2 have been administered worldwide. Although severity new cases has progressively decreased, and pressure on national health systems declined, development de novo glomerular injuries suggested. Methods: This study aimed to examine patients who were hospitalized in our Unit between April November 2021 underwent renal biopsy for new-onset urinary abnormalities (UA) and/or impairment within 3 months vaccination. Results: We identified 17 developed UA insufficiency Minimal change disease was most common cohort (5 patients, 29.4%) followed by acute tubulointerstitial nephritis (TIN; 17.6%), membranous nephropathy (3 rapidly progressive IgA (2 11.8%). The other 4 had a diagnosis membranoproliferative glomerulonephritis (1 patient), systemic lupus erythematosus ANCA-associated vasculitis tip-variant focal segmental glomerulosclerosis respectively. Eight out (47.1%) kidney injury. Two with TIN start hemodialysis that discontinued after 1 2 months, respectively, due recovery function. All treatment corticosteroids immunosuppressants. Discussion: it is not possible conclusively determine whether there causal relationship vaccination nephropathies, based appearance shortly vaccination, we hypothesize immune response COVID-19 may be trigger nephropathies. Therefore, results highlight need pharmacovigilance. However, this report should lead hesitation during pandemic as benefits strongly outweigh potential risks.
