rMVAs
Experimental COVID-19 virus-vectored vaccines.
General information
rMVAs is a group of experimental vaccines based on modified vaccinia virus Ankara (replication-restricted viral system) encoding wild type or recombinant SARS-CoV-2 Spike protein variants (Liu et al., 2021).
Synonyms

Immunized K18-hACE2 mice were protected in a SARS-CoV-2 challenge (based on observations of weight loss, lung and nasal turbinate viral titres, and proinflammatory cytokine levels). RBD of Spike protein (adjuvanted) alone was able to potently boost antibody responses after a single rMVA vaccination. Results for different vaccine constructs varied and some of the experiments were performed only on smaller subsets of the vaccine variants. |
