I agree and also think that too much focus is being placed on a vaccine, which will be subject the concerns that have existed with most vaccines in general usage in the population, namely that sooner or later someone finds a link with some condition that appears to have been triggered by having the vaccine.
Compare that 'new' vaccine risk to the same risk with a 'new' therapy that may carry similar risks - the risk equation is completely different. With a vaccine, you're taking healthy people and asking them to take a risk of having a new vaccine (with relatively unknown side-effects) to protect against the risk of getting a virus they may or may not get. With a therapy, you're dealing with people that already have the disease and may be seriously ill with it/deteriorating. That population would be prepared to take significantly more risk with a new therapy because they have far fewer options open to them - it's a completely different choice.
I think there are five pillars to the Covid response:
1. Science / pathology of the virus - this underpins everything else, but has little commercial value in its own right. Avacta is contributing, but no commercial developments.
2. Antigen testing - critical to control the spread of the disease and probably even more critical to sustainably opening up economic activity. Massive commercial opportunity because of the potential to unlock domestic and global economies. Avacta is developing multiple mass-market products in this space.
3. Antibody testing - important to understand the pattern of the spread of infection levels throughout the population, but opinion divided on whether knowledge of whether individuals have had the disease is of any practical help in terms of what that then means in terms of both personal immunity and propensity to infect others. Uncertain commercial opportunity and Avacta isn't playing in this space.
4. Vaccine - seen as the holy grail, but huge obstacles to overcome both in terms of efficacy, scale and speed of production and competition, any of which could scupper an individual company's product. Huge potential to ultimately resolve the pandemic, but major uncertainties and likely to take significant time to build public confidence. Avacta isn't playing in this space.
5. Therapy - seems to be developing at a much slower pace than the other pillars, but good medical practice appears to now be having a significant impact on patient outcomes. It is, however, predicated on using established drugs (e.g. Dexamethasone) to treat the symptoms rather than inhibit the spread of the disease. Commercial potential for a novel therapy would seem to be very high. Avacta is seeking to break completely new ground in this space with a treatment that could have both therapeutic and prophylactic potential.
Looking at it this way, Avacta really does seem to be playing in the three areas that have the most commercial potential.
