New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks
In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the
bioRxiv preprint server.
Vaccines currently in use against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a causative agent of COVID-19, focus on the viral spike glycoprotein that mediates cell entry by targeting angiotensin receptor 2 (ACE2) as the main receptor and heparin as the co-receptor.
