Scientists develop effective intranasal mumps-based COVID-19 vaccine candidate

New research has advanced COVID-19 vaccine work in several ways: using a modified live attenuated mumps virus for delivery, showing that a more stable coronavirus spike protein stimulates a stronger immune response, and suggesting a dose up the nose has an advantage over a shot.

Hormone Drugs May Disarm COVID-19 Spike Protein and Stop Disease Progression

Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press’s iScience.

Glycans in the SARS-CoV-2 spike protein play active role in infection

As researchers try to develop therapies/vaccines to combat SARS-CoV-2, the coronavirus spike protein is a major focus since it can bind to cells. Now, researchers reporting in ACS Central Science have uncovered an active role for glycans in this process, suggesting targets for vaccines and therapies.

Study Reveals New Targets for Next-Generation COVID-19 Vaccines and Tests, Beyond Antibodies

This clinical trial increased an understanding of how T cells mount a response to COVID-19 infection. These findings pave the way for diagnostic tests that detect COVID immunity based on T cells instead of antibodies. Research demonstrates that generating neutralizing antibodies rather than T cells, may not be sufficient for long-term immunity. New discoveries suggest that vaccines will need to incorporate T cell targets to generate lasting COVID-19 immunity.
