This is a limited point about availability of efficacy data for vaccines under development in the context of the approval for CovidShield and Covaxin in India.
There have been many so-called experts on the idiotbox opining about apparent availability of P III data which 1/n
Here is one set of efficacy data post the interim analysis of a mRNA vaccine.

How does the SEC, or the sponsor of these studies, or the experts who are offering their opinion liberally on the idiotbox know what the efficacy is
A. Do they know if the blind was broken for the bridging study and the Phase III study?
B. If so, can they produce data like the one above showing how many subjects who were infected were
And if they cannot answer this question, then ask the following question:
C. In the absence of efficacy data, how does one claim that the vaccine candidate is effective?
D. Do they agree that therapeutic candidates ought to be approved

Before we get too far into 2021, I thought I’d write a thread recapping some of the research that came out of my lab in 2020. Most of this work was led by my talented team of graduate students, Kerrianne Morrison, @kmdebrabander, and @DesiRJones.
Back in January, a news story was published about Kerrianne’s study showing improved social interaction outcomes for autistic adults when paired with another autistic partner.
A detailed thread about the study and a link to the paper can be found here (feel free to DM me your email address if you’d like a copy of the full paper for this study or any of our studies):
Another paper published early in 2020 (it appeared a few months earlier online) showed that traditional standalone tasks of social cognition are less predictive of functional and social skills among autistic adults than commonly assumed in autism research.
Next, @kmdebrabander led and published an innovative study about how well autistic and non-autistic adults can predict their own cognitive and social cognitive performance.

In our new paper out today, autistic adults held a \u201cget to know you\u201d conversation with an unfamiliar autistic or typically-developing (TD) person. We were curious: would social interaction outcomes differ when their partner was also autistic? THREAD https://t.co/4koqUKV9G1

How well does social cognition predict functional and social skills in autism? Our new paper attempts to answer this question. This thread summarizes why we conducted the study, what we found, and why I think it\u2019s important. https://t.co/KB1nIpK0M2

New by @kmdebrabander and our lab: Autistic adults don\u2019t differ from non-autistic adults in the accuracy of their self-assessment on general cognitive tasks but are less accurate on social cognitive tasks. This however was unrelated to social functioning https://t.co/0MrqMKKO0r

No-regret #hydrogen:
Charting early steps for H₂ infrastructure in Europe.
👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em
The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

Sarcomeres in cardiac myocytes (heart muscle cells) are mechanically coupled to focal adhesions through dorsal stress fiber-like structures. #cardiotwitter #CellBiology

A thread based on Figure 1
A mature adult cardiac myocyte is packed with sarcomeres, whose contractile forces are coupled to the extracellular environment. With sarcomeres so close to the plasma membrane, how can we study the nature of this coupling?
2/13
Short answer: find a model system where the sarcomeres are not so close to what the cardiac myocyte is attached to. Enter, iPS cell-derived cardiac myocytes. These are “immature” in culture as they resemble fetal or neonatal cardiac myocytes.
3/13
Our previous work on iPS cardiac myocytes reported that sarcomere containing myofibrils assembled on the top surface of the myocyte.

The sarcomeres seemed to be connected to focal adhesions on the bottom of the cell by thin actin bundles that resembled the dorsal stress fibers (DSF) commonly found in non-muscle cells. This movie steps through a Z stack of a myocyte starting at the bottom of the cell.
