Different type of vaccine being developed at Scottish factory of a French company - an “inactivated whole virus” - UK task force secured 60m dose preorder in July for €470m with options for 130m more 2022-25, invested in factory. EU finalised first order of 30m this month.
It\u2019s brilliant that @ValnevaSE is starting the large-scale manufacture of its potential vaccine, creating 100 high-skilled jobs at their Livingston facility.

We\u2019ve secured 60m doses due to be delivered by the end of the year if it is approved for use.https://t.co/4pDUbczlVl
EU focussed on lower price, & helping smaller EU nations
Not sure EU approach clocks intimate involvement/ risk taken by UK Govt here...
But then at point Biontech did a deal with Pfizer, either have blocked that or insisted on first use in the EU, and paid handsomely, over odds for pleasure

Ok here is the explanation. Grab a cup of coffee and read on. If you have not read/noticed this, you will see intraday options movement in a new light.
Say we have two options, one 50 delta ATM options and another 30 delta OTM option. Normally for a 100 point move, the ATM option will move 50 points and the OTM option will move 30 points. But in a high volatile environment, the OTM option will also move nearly 50 points
To understand why this happens, first understand why an ATM option is 50 delta. An ATM option has the probability of 50% of expiring as ITM. The price just has to close a rupee above the strike for the CE to be ITM and vice versa for PEs
Now think of a highly volatile day like today. If someone is asked where the BNF will close for the day or expiry, no one can answer. BNF can close freakin anywhere, That makes every option of an equal probability of being ITM. So all options have a 50% probability of being ITM
Hence, when a huge volatile move starts, all OTM options behave like ATM options. This phenomenon was first observed in the Black Monday crash of 1987 at Wall Street, which also gave rise to the volatility skew/smirk
In a high IV environment or when the market is very volatile

" OTM options will behave like ATM options", one will get almost the same delta movement

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.
Legacy site *downloads* ~630 KB CSS per theme and writing direction.
6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors

PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.
735 rules
740 selectors

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.
The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
