Strategies of vaccine production against COVID-19: when will an effective vaccine be produced?

There is a strong consensus globally that production of an effective vaccine against SARS-CoV-2 is likely the most effective approach to sustainably controlling the COVID-19 pandemic. An unprecedented research effort and global coordination has resulted in a rapid development of vaccine candidates and initiation of trials. In this paper, we review vaccine candidate against COVID-19 and also cha...

Gaudry's Variant against Cab Curves

Gaudry has described a new algorithm (Gaudry’s variant) for the discrete logarithm problem (DLP) in hyperelliptic curves. For a hyperelliptic curve of a small genus on a finite field GF(q), Gaudry’s variant solves for the DLP in time O(q2+2). This paper shows that Cab curves can be attacked with a modified form of Gaudry’s variant and presents the timing results of such attack. However, Gaudry’...

Does BCG vaccine induced trained immunity provide cross-protection against COVID-19?

During the global COVID-19 pandemic, the rate of mortality and morbidity was fairly low in Pakistan compared to western countries. Bacille Calmette-Guerin (BCG) vaccination provides cross-protection for a broad range of related and unrelated pathogens. This protection is attributed to the recognition of broadly cross-reactive Pathogen-Associated Molecular Pattern (PAMPS) like molecules. We inve...

Promoter Variant of PIK3C3 Is Associated with Autoimmunity against Ro and Sm Epitopes in African-American Lupus Patients

The PIK3C3 locus was implicated in case-case genome-wide association study of systemic lupus erythematosus (SLE) which we had performed to detect genes associated with autoantibodies and serum interferon-alpha (IFN-alpha). Herein, we examine a PIK3C3 promoter variant (rs3813065/-442 C/T) in an independent multiancestral cohort of 478 SLE cases and 522 controls. rs3813065 C was strongly associat...
