Coronavirus Vaccines Pathway
Unprecedented efforts are being made to develop a safe and effective vaccine against SARS-CoV-2.More than 90 vaccines are being developed against SARS-CoV-2 by research teams in companies and universities across the world. All vaccines aim to expose the body to an antigen that won’t cause disease, but will provoke an immune response that can block or kill the virus if a person becomes infected. There are at least eight types being tried against the coronavirus, and they rely on different viruses or viral parts (colored bars). These include 1) virus-based, live attenuated (weakened) or inactivated, 2) viral-vector based, replication and non-replicating (e.g. S protein expressing), 3) Protein-based (e.g. S protein and subunits) and virus-like particles (VLPs), 4) Nucleic acid based, DNA-based, and RNA-based vaccines.
