So here's an update on the abandoned UQ COVID vaccine named UQ-CSL v451

uq.edu.au/news/node/1279… First, the release states that the vaccine worked: vaccine elicited a response and "There were no serious adverse events or safety concerns reported in the 216 trial participants"

WELL I'm going to have to dig into this. Reminder that vaccine development is not straightforward, despite the super-exciting day we are having watching #VRBPAC

Australian COVID vaccine terminated due to HIV ‘false positives’ smh.com.au/politics/feder… "The UQ vaccine candidate uses a protein and adjuvant platform, containing the COVID-19 spike protein and a "molecular clamp". A small component is derived from.... HIV, that is not able to infect people or replicate."

Any details out there?

Our @NIHDirector says @ncats_nih_gov have been "everywhere you look" on COVID-19 science !!

Part of a @MilkenInstitute Conversation with Dr. Francis Collins, Director, @nih (and Michael Milken)

vimeo.com/486353483 There were three examples that @NIHDirector gave.

First, tackling a battery of assays, screening of all libraries for SARS-COV-2, and sharing data openly through our OpenData Portal

Well - huge issues here. Not sure this article will be around for long.

And it's just samples collected for a completely different study (on asthma), and they checked TMPRSS2.

"Race" isn't mentioned in the awarded R01 - it's an asthma grant from NIAID.
grantome.com/grant/NIH/R01-… I have a terrible feeling that ran TMPRSS2 expression on their samples, looked for a differential based on what they know about study sample donors (rather than having a hypothesis), and were like "welp, 'race' is a thing with COVID let's go with that".

OK so let's talk about camostat, because I'm starting to worry about it as a #COVID19 repurposing candidate. It emerged based on this Cell paper, but a LOT of assumptions are buried in the science.
cell.com/cell/fulltext/… Image That Cell paper calls camostat "calls camostat “a clinically proven inhibitor of the cellular serine protease TMPRSS2” – which is not strictly correct.

It’s a clinically used drug (in Japan)

It has been shown to act on TMPRSS2 indirectly

Separate points. @Dereklowe

This article on a 'miracle cure' for cancer has me so angry. How can unpublished, non-peer reviewed tripe get any attention at all? Some of the issues are in the thread below:
jpost.com/HEALTH-SCIENCE… First, the experimental theraputic modality is based on phage-display-derived peptides against various targets that are apparently coupled together with a 'peptide toxin'. Presumably the peptide toxin is Monomethyl auristatin E
