Ingenious designs for medical ventilators - including from Dyson and other large companies. Some of the 'DIY' and 'open source' designs nevertheless might be very valuable for developing countries, as might the CPAP designs some developed via the NHS in the UK.
very readable article by George Monbiot outlining many of the 'community initiatives'
that have been spawned by the Covid-19 pandemic.

It seems rather telling that while these designs can apparently be produced within a couple of weeks the usual time-scale for product design is several years and the costs are typically 10 to 50 times that of units that may work quite reasonably, except maybe for the patients who are very seriously ill!
One problem is that since the 1960s, tests of vaccine candidates for diseases such as
dengue, respiratory syncytial virus (RSV), and severe acute respiratory syndrome (SARS)
have shown a paradoxical phenomenon: some animals or people who received the vaccine and
were later exposed to the virus developed more severe disease than those who had not been
vaccinated. The vaccine-primed immune system, in certain cases, seemed to launch a shoddy
response to the natural infection. This can be called immune backfiring or "immune
enhancement". The WHO can refer to the phenomenon by a different name as
"vaccine enhancement". In simple terms, in some cases, in some people, a vaccine
of this type might well help to kill you. Hence much care is needed in development and
These difficulties, even if they are understood by journalists and politicians (which I doubt) are glossed over in the search for a positive story.
One of the leading UK experts is Prof Sarah Gilbert at Oxford - interviewed on the Andrew Marr show.
One of the puzzles about Covid 19 is why some people are so much more badly affected than others
Gene testing to try and determine why is discussed here.
Prof Paul ROMER is a nobel prize winner. He weighed into the discussion of how to lift lockdowns via testing, whilst Julian Peto advocated a city by city approach. (Discussed on R4 15 April 2020).
Discussed in only one paper I found - a novel approach, Two references are given below - a high success rate is claimed.
