SARS-COV-1 transmitted when an individual had symptoms, the son of the virus, CV-19, transmits prior to symptoms being expressed.
Subclinical carriage and transmission also occurred in SARS COV-1. The main difference is that it was less infectious and more pathogenic.
It was contained and vaccine development put on indefinite hold. But the work on SARS-COV-1 vaccine helped speed up current endeavours, as well as more recent developments with ‘plug and play’ vaccines technology.
Of course. The main reason for me bringing this up was in response to a comment that there had never been a vaccine successfully brought to market for any coronavirus. This is true, but there are reasons for this other than that it is impossible or had never been attempted.
Also note that Australian company CSL began commercial production of the Oxford University Astra-Zeneca COVID-19 vaccine today (9 November 2020) before phase 3 trials are complete and well before any regulatory authority has approved its use. They are essentially betting on it working and being ahead of the game. I can think of no other set of circumstances where anything like this has happened with a human vaccine, ever. Unprecedented times.
I do not think farming Mink is a good idea, and it is definitely interfering with the “natural order“. If left on their own the mink would not congregate in such numbers, and would not be in such close contact with humans.
Over 17 million mink are being culled as a result of reckless greed to sell their fur.
Sheer madness to ‘farm’ animals in this way.
There is only a philosophical difference between farming mink and any other intensive animal industry. Chickens and other poultry, pigs, salmon and other animals are farmed this way. It concentrates the environmental impact and minimises the spatial footprint. It is extremely efficient. Among the downsides are that you need good biosecurity to minimise zoonoses and animal diseases.
And it's impossible to be a film/traditional silver photographer and not support intensive animal production - high bloom photographic gelatin all comes from intensively reared livestock.
It's only obliquely relevant, but I bought my first Leica with money I earned from fox pelts from animals I shot on my great aunt's farm in the 1980s, before the fur price tanked.
Indeed. On a beside, in the past, most vaccines were developed by academics and non-profit labs, while today, the task is outsourced to multinational companies managed by CEOs primarily concerned with stock value and their bonuses. Cheers, OtL
Most vaccines are still developed by academics in not-for-profit labs, but the logistic, economic and scale of production contraints that need to be overcome to bring vaccines to market in the current climate is beyond these types of institutions. I have been involved in the development of a number of vaccines, and the point at which academics hand them over is generally at the point where it becomes impossible for that lab to go further without the support of a large entity that has the resources to push the product through the next step(s). This is what happened with Gardasil/HPV vaccine:
