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

2/n apparently the SEC had access to based on which it "supposedly" approved Covaxin. Another argument that is prevalent is other regulators (US FDA and MHRA) also approved vaccines based on P II data alone. Let me give you a few facts so that you can make your own decision.
3/n The protocols for both mRNA vaccines are publicly available. You can check. Both protocols *define* when the interim analysis will be done. This is not subjective. They clearly define how many infections need to be documented before the Data Safety Monitoring Board meets.
4/n Find the protocols for the bridging study for CovidShield and Covaxin and look for a similar milestone.

Here is one set of efficacy data post the interim analysis of a mRNA vaccine.

5/n This data was analyzed post the interim analysis where the blind was broken by the DSMB. Now ask yourself this question:
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
6/n without the blind being broken? Do they have some divine insight into how the vaccine candidates are working? On what basis are they offering their considered opinion? Is that a valid question? Or is it that asking it makes one anti-national?
7/n To those who interview these experts, please ask the following simple questions:

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
8/n on placebo Vs the vaccine candidate?

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
9/n just based on Phase II data? This is a yes or no question. Dont let them confuse the issue saying this is an emergency situation. Science doesnt work differently in emergencies.

If the decision is based on considerations other than Scientific, say that. Dont hide behind

Some thoughts on this: Firstly, it might be personal preference, but I am not keen on this kind of campaign as I feel like it trivialises cancer. Sometimes the serious message gets lost because people are sharing pics of cats or whatever and the important context is gone.


More importantly, the statistic being used in the campaign is misleading. It says 57% of women put off cervical screening if they can't get waxed. But on further investigation, that's not accurate.

The page here goes on to say "57% of women who regularly have their pubic hair professionally removed would put off attending their cervical screening appointment if they hadn’t been able to visit a beauty salon."

So the 57% represents a concern not across the whole population of women, but only those who regularly get waxed. So how big of an issue is this across the whole population? And what else is stopping people getting smears?

I think campaigns for cancer screening are really tricky because there is so much nuance that often doesn't fit into a catchy headline or hashtag. It's certainly not easy and is part of a bigger conversation.

The first ever world map was sketched thousands of years ago by Indian saint
“Ramanujacharya” who simply translated the following verse from Mahabharat and gave the world its real face

In Mahabharat,it is described how 'Maharishi Ved Vyasa' gave away his divine vision to Sanjay


Dhritarashtra's charioteer so that he could describe him the events of the upcoming war.

But, even before questions of war could begin, Dhritarashtra asked him to describe how the world looks like from space.

This is how he described the face of the world:

सुदर्शनं प्रवक्ष्यामि द्वीपं तु कुरुनन्दन। परिमण्डलो महाराज द्वीपोऽसौ चक्रसंस्थितः॥
यथा हि पुरुषः पश्येदादर्शे मुखमात्मनः। एवं सुदर्शनद्वीपो दृश्यते चन्द्रमण्डले॥ द्विरंशे पिप्पलस्तत्र द्विरंशे च शशो महान्।

—वेद व्यास, भीष्म पर्व, महाभारत


Meaning:-

हे कुरुनन्दन ! सुदर्शन नामक यह द्वीप चक्र की भाँति गोलाकार स्थित है, जैसे पुरुष दर्पण में अपना मुख देखता है, उसी प्रकार यह द्वीप चन्द्रमण्डल में दिखायी देता है। इसके दो अंशो मे पीपल और दो अंशो मे विशाल शश (खरगोश) दिखायी देता है।


Meaning: "Just like a man sees his face in the mirror, so does the Earth appears in the Universe. In the first part you see leaves of the Peepal Tree, and in the next part you see a Rabbit."

Based on this shloka, Saint Ramanujacharya sketched out the map, but the world laughed
