Recently various sources have pitched the Pfizer vaccine for India. This parlays the recent western ‘branding’ effort differentiating Pfizer, but it is known that this vaccine has some unique technical requirements.
This thread analyzes the Pfizer logistics in depth.
The vaccine must be stored at -60 to -80C, i.e. ultra low temp (ULT), much colder than normal freezer (-20C) or fridge (2 to 8C). Such storage systems are costly but cost depends on capacity. These have alarm systems to notify of failure or temperature fluctuations.
The Pfizer transport box shows ~5000 doses = 10L tray volume. It is packed with dry ice and can be transported for no more than 10 days unopened, 15 if dry ice recharged. Each pallet has IoT comm to notify Pfizer of problems: truckinginfo.com/10134508/vacci… bbc.com/news/technolog…
Great thread that takes apart WSJ's predictable opposition to the TRIPS waiver that would help expand COVID vaccine production. The @WSJ is stridently focused on avoiding any attempt to learn from history.
This thread covers their production effort, scaling and some other factors. Starting with SII:
SII started out with 50-60 million doses/mth capacity. Apr 1 it announced efforts to scale up to 100m by May using internal resources, and requested Rs.3000cr funding to scale up. The bulk order came thru mid April, enabling further scale up and deliveries through May/June.
A common mistake made is to extrapolate latest prices to all future orders. Prices are tied to capital costs of scaling up and order size. Early SII orders were Rs.200/dose + GST. The higher initial price Is due to setup and initial investment SII made, described later.
Observations: 1. SII-AZ signed the Covishield licence prodn deal to enable COVAX supply, so $3/dose is baseline 2. SII supplied 50m doses at that price, another 100m doses at 66% of that price to Indian govt.
The second deal significantly stressed SII, supplying so far below cost. Same vaccine made in EU goes for $4-6 (Rs.300-450) per dose. SII pays ~Rs.75 per dose as royalty to AZ. At Rs.150/dose it makes only Rs.75.
This thread describes the progress of Indian electrification coverage. Two charts are presented, both sourcing data from EIA.
Observations: 1. By the start of the century China had already almost finished full electrification. India had 60% without electricity. 2. Big drop 2000-04, from 600m to 500m 3. Shallow drop 2004-14 from 500m to 350m 4. Big drop 2014-18 from 350m to 50m
Note: 1. slope of electrification rate from 2000-04 and since 2014 exceeds peak rate of electrification in China 2. 2017 was start of Saubhagya mission. 3. By 2019, India achieves near complete electrification (next graph)
There's a lot of talk about India and climate change goals. Particularly, it is argued that the Indian government lacks commitment. This thread is intended to offer an overview of current status. It will be data focused.
The most recent epoch of data is the annual climate transparency report: climate-transparency.org/wp-content/upl…
All major nations are rated by their ongoing progress against Paris Agreement Nationally Determined Contributions (NDC 2015) towards their 2030 target goals.
Page 23 is of particular interest. All major nations listed with status:
USA: critically insufficient
China: highly insufficient
Japan: highly insufficient
