[107] [108] [109] The 'Ellume COVID-19 Home Test' is a rapid, lateral flow antigen test, a type of test that runs a liquid sample along a surface with reactive molecules. [107] The test detects fragments of proteins of the SARS-CoV-2 virus from a nasal swab sample from any individual two years of age or older. [ 107 ]
The Sanofi–GSK COVID‑19 vaccine is a recombinant protein subunit vaccine containing the SARS-CoV-2 spike protein, which is produced in insect cells via a baculovirus vector. It also includes an adjuvant made by GSK. It uses the same technology as Sanofi's Flublok influenza vaccine. [8] [9]
