Inhalable COVID-19 vaccine? Rice University scientists developing vaccine spray in fight against coronavirus Published: Tags: In this rendition, a phage particle displays a region of the SARS-CoV-2 spike protein that retains a near-native structural conformation. Administration of this phage in mice induces a systemic immune response against the spike protein. This versatile technology serves as a first step towards developing cost-effective and easy-to-manufacture vaccines for COVID-19 and other infectious agents.
