    Besides the obvious immediate harm from doing something this foolish, this will also be a massive boon to the anti-vaccine movement. It's impossible to overstate how damaging to public perception of vaccines releasing a likely invalid, for lack of proper testing, vaccine will be.

    This is very likely to be a done deal. If not this one it may be another one, politics are driving the issue and no one is willing and able to stop this, the personal risk is too high.

    Thanks, Richard Horton, for having released this genie out into the wild. That he is still the editor of the Lancet is one of the most catastrophic errors of judgment I have seen from a supposedly serious institution.

    I'm becoming very concerned by reports coming out of the USA that there is pressure to get a vaccine out by the beginning of November (remind me what the election date is, please, someone?) Here's an example:

    If the situation is as politicised as it appears to be becoming, then I find that absolutely appalling - public bodies shouldn't be partisan in such a case, in particular when lives are at stake. I hope no corners will be cut.

    Post copied from the Possibility of ME or PVFS after COVID-19 thread

    Last night on CNN Chris Como interviewed Dr. William Li who says it appears that COVID is a 'blood vessel disease' causing severe damage to the vascular system, which would explain why the virus seems to be affecting all organs.

    Dr Li is an internal medicine physician and a research scientist—specifically a vascular biologist. He’s been actively involved in angiogenesis research and clinical analysis for more than two decades. Angiogenesis is the development of new blood vessels and Dr. Li is one of the world’s leading experts in this field.

    Broad and strong memory CD4+ and CD8+ T cells induced by SARS-CoV-2 in UK convalescent individuals following COVID-19

    Notably:
    This contradicts the suggestion by Mateus et al. and Grifoni, A. et al. who suggested there was partial T-cell immunity acquired from prior coronavirus infections. I previously wondered whether this was merely naive T-Cell cross reactivity, or low-affinity reactivity and would not provide a robust immune response.

    Note that this was in a "brain organoid" (in-vitro) model. Thus, it is only suggestive of what could happen to real people and says nothing about how common this may be.

    The best part is that the cost of the steroid drug is cheap.

    Yes, affordable and widely available for the rest of the world (Asia, South America)! Compared to Remdesivir which costs over $5000 and doesn't save lives...

    Amazing isn't it, one patient has a suspected adverse reaction of unknown cause and they pause the whole trial.
    Yet people dropped out of the PACE study and they just carried on as if nothing had happened.

    The adverse reaction has to be in the "serious" category for them to call a halt. It could be a coincidence, e.g. someone suffering from a stroke, or it could be a reaction that is probably associated with the vaccine (Guillain Barre Syndrome).

    I'm not sure how many people they have enrolled so far, but if 10,000+, a coincidence might not be unheard of.

    The Phase 2 trial had a high proportion of people suffering from headache, fever, so I still wonder about (rare) serious immunological reactions.

    edit - I should have read the article, as it had a new report about the underlying condition that wasn't a part of previous news reports.
    edit 2 - Is this a second case of transverse myelitis or is the earlier (July) case being cited incorrectly?

    Transverse myelitis is an inflammation of both sides of one section of the spinal cord. This neurological disorder often damages the insulating material covering nerve cell fibers (myelin). Transverse myelitis interrupts the messages that the spinal cord nerves send throughout the body.

    Ah, the news reports earlier today did not report the actual condition.

    Transverse myelitis is similar to Guillain Barre Syndrome and sometimes GBS is misdiagnosed as Transverse myelitis or vice versa.

    And sometimes they occur at the same time...
