In this week in virology episode 730 in Covid 19 clinical update Dr Daniel Griffin explains the concept of a sequence in the spike protein that does not change if it is to infect humans . -It is called the "conserved " part of the spike protein . -It is a required sequence for the virus to infect human cells . This proposes that if it mutates or is neutralised by antibody it loses infectivity . -An antibody VIR-7831 targets this conserved sequence and it has been used in a trial called COMET-ICE - by gsk -Vir Bio with a interim analyses of 583 patients with claimed 85 % reduction in hospital admission and death compared to patients that received placebo .
But is this an ethical way to test medications ? You can use matched controls who have no way possible of getting this treatment .

Those are interesting anaphylaxis stats. We have had at least three at our site and we have not given a huge number of vaccinations. This is in Canada and these do get reported through our public health, so I'm wondering if there is a lag in reporting.

Still holding at about 2.5 per million per CDC after 4 million Moderna vaccinations, a little higher for Pfizer.
