Bacteria Make Antivirals
Viperin is a conserved antiviral protein that catalyzes the synthesis of chain terminator molecules in both vertebrates and prokaryotes.

SARS-CoV-2 variants of concern
In recent months variants of SARS-CoV-2 have been detected that are unusual in that they have many more genome mutations than previously found. These have been called ‘variants of concern’ (VOC) as it has been suggested that the genome mutations might impact transmission, immune control, and virulence. Below I cover each of these issues separately. …
Camelids for COVID
Human monoclonal antibodies that block infection with SARS-CoV-2 are being used to treat COVID-19 patients, but an alternative, antibodies produced in camelids (alpacas and llamas) might have advantages. Camelid monoclonal antibodies can be more cheaply produced in mass quantities in bacteria, and protein engineering can be quickly used to produce a better therapeutic product. Human …
RNA, in a Nutshell
The mRNA vaccine platform is based on decades of previous studies, highlighting the importance of regularly funding basic research.
SARS-CoV-2 UK variant: Does it matter?
A variant of SARS-CoV-2 has been spreading within England, and it has been suggested that this virus is more transmissible. In this video Vincent explains the properties of the SARS-CoV-2 UK variant and why claims that it is more transmissible are not supported by experimental data. This video was recorded on Monday, 21 December 2020. …
An antiviral compound that blocks SARS-CoV-2 transmission in ferrets
COVID-19 vaccine candidates are garnering all the news these days, which is appropriate as they are our key to ending this pandemic. Earlier in this outbreak antiviral drugs received a good deal of attention, but they have proven less useful in curtailing infection. Less discussed are the many antiviral drug candidates that are in testing, …
