Enhancement of cellular immunity following needle-free vaccination of mice with SARS-CoV-2 spike protein.

The COVID-19 pandemic has highlighted the need for vaccines capable of providing rapid and robust protection. One way to improve vaccine efficacy is delivery via microarray patches, such as the Vaxxas high-density microarray patch (HD-MAP). We have previously demonstrated that delivery of a SARS-CoV-2 protein vaccine candidate, HexaPro, via the HD-MAP induces potent humoral immune responses.

Superior efficacy of a skin-applied microprojection device for delivering a novel Zika DNA vaccine.

Zika virus (ZIKV) infections are spreading silently with limited global surveillance in at least 89 countries and territories. There is a pressing need to develop an effective vaccine suitable for equitable distribution globally. Consequently, we previously developed a proprietary DNA vaccine encoding secreted non-structural protein 1 of ZIKV (pVAX-tpaNS1) to elicit rapid protection in a T cell-dependent manner in mice.

Long-term safety and immunogenicity of an MF59-adjuvanted spike glycoprotein-clamp vaccine for SARS-CoV-2 in adults aged 18-55 years or ≥56 years: 12-month results from a randomised, double-blind, placebo-controlled, phase 1 trial.

Background: We previously demonstrated the safety and immunogenicity of an MF59-adjuvanted COVID-19 vaccine based on the SARS-CoV-2 spike glycoprotein stabilised in a pre-fusion conformation by a molecular clamp using HIV-1 glycoprotein 41 sequences. Here, we describe 12-month results in adults aged 18-55 years and ≥56 years.

Methods: Phase 1, double-blind, placebo-controlled trial conducted in Australia (July 2020-December 2021; ClinicalTrials.

Chloroplast genome, nuclear ITS regions, mitogenome regions, and Skmer analysis resolved the genetic relationship among Cinnamomum species in Sri Lanka.

Cinnamomum species have gained worldwide attention because of their economic benefits. Among them, C. verum (synonymous with C.

Low- Versus High-dose Cyclophosphamide in Class III/IV Lupus Nephritis: A Retrospective Study from South Asia.

Introduction: The comparative efficacy of low-dose cyclophosphamide (LD-CYC) and high-dose cyclophosphamide (HD-CYC) for treatment of lupus in South Asians is not well established. We aimed to compare treatment outcomes in South Asian patients with class III and IV lupus nephritis treated with either regimen.

Method: This was a single-center, retrospective study conducted in Sri Lanka.
