The We-Care project is a novel initiative by University of California, Davis researchers that uses anonymity and crowdsourced information to alert infected users and slow the spread of COVID-19. [58] [59] [60] The scientific community has held several machine learning competitions to identify false information related to the COVID-19 pandemic ...
COVID-19 vaccine clinical research uses clinical research to establish the characteristics of COVID-19 vaccines. These characteristics include efficacy , effectiveness , and safety. As of November 2022 [update] , 40 vaccines are authorized by at least one national regulatory authority for public use: [ 1 ] [ 2 ]
Today, a significant proportion of vaccines against viral diseases are created using nanotechnology. Solid lipid nanoparticles represent a novel delivery system for some vaccines against SARS-CoV-2 (the virus that causes COVID-19). [60] In recent decades, nanosized adjuvants have been widely used to enhance immune responses to targeted vaccine ...
Early in the pandemic, he said, research moved quickly, with researchers desperate to better understand the SARS-CoV-2 virus that causes COVID-19, and find effective treatments for very sick people.

As of late 2020, several mRNA vaccines for SARS-CoV-2 use LNPs as their drug delivery system, including both the Moderna COVID-19 vaccine and the Pfizer–BioNTech COVID-19 vaccines. [4] Moderna uses its own proprietary ionizable cationic lipid called SM-102, while Pfizer and BioNTech licensed an ionizable cationic lipid called ALC-0315 from ...
How COVID‑19 vaccines work. The video shows the process of vaccination, from injection with RNA or viral vector vaccines, to uptake and translation, and on to immune system stimulation and effect. Part of a series on the COVID-19 pandemic Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom. COVID-19 (disease) SARS-CoV-2 (virus) Cases Deaths ...
