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

Let's talk honestly about "informed consent."
Someone with decades of training gives someone with none advice usually packed into 1-3 mins. Huge amount is based on trust. Huge potential for bias built in. But also there is no obligation to provide real alternative options.


I am classified as 'gifted' (obnoxious and ableist term). I mention because of what I am about to say. You all know that I was an ambulatory wheelchair user previously - could stand - but contractures have ended that. When I pleaded for physio, turned down. But did you know...

I recently was chatting with a doctor I know and explaining what happened and the day the physiatrist told me it was too late and nothing could be done. The doctor asked if I'd like one of her friends/colleagues to give second opinion. I said yes please! So...

She said can you send me MRI and other imaging they did to determine it wasn't possible to address your contractures.

Me: What?
Dr.: They did a MRI first before deciding right?
Me: No
Dr: What did they do??!
Me: Examined me for 2 minutes.
Dr: I am very angry rn. Can't talk.

My point is you don't even know if you are making "informed" decisions because the only source of information you have is the person who has already decided what they think you should do. And may I remind you of a word called 'compliance.'

முதல்வரி: பிறவி என்பது முன்வினை விதையால் முளைப்பதோர் பெருமரம். அந்த ‘முன்வினை’ எங்கு ஆரம்பித்தது எனச் சொல்ல இயலாது. ஆனால் ‘அறியாமை’ ஒன்றே ஆசைக்கும்,, அச்சத்துக்கும் காரணம் என்பதால், அவையே வினைகளை விளைவிப்பன என்பதால், தொடர்ந்து வரும் பிறவிகளுக்கு, ‘அறியாமையே’ காரணம்

அறியாமைக்கு ஆரம்பம் கிடையாது. நமக்கு ஒரு பொருளைப் பற்றிய அறிவு எப்போதிருந்து இல்லை? அதைச் சொல்ல முடியாது. அதனாலேதான் முதலடியில், ஆரம்பமில்லாத அஞ்ஞானத்தை பிறவிகளுக்குக் காரணமாகச் சொல்லியது. ஆனால் அறியாமை, அறிவின் எழுச்சியால், அப்போதே முடிந்து விடும்.
