Let's talk about Vaccines.

Still seeing a lot of confusion going around about the Mechanism of vaccines in use. I will attempt to explain it as simply as possible.

Please read, and share.

So, think of the SARS-CoV-2 virus as Ferrero Rocher. 😋😋

1/n

Let's see the structure of the virus first.

Spike Protein = Nutty spikes
Lipid Membrane = Outer Chocolate Layer
Nucleocapsid = Wafery Layer
RNA = Innermost Chocolate

That's putting it very simply for the purpose of understanding.

2/n
Let's see how the virus causes infection.

The virus enters through our respiratory tract. It needs to enter a cell to replicate. For that, it uses the SPIKE PROTEIN (nutty spikes).

Spike protein allows the virus to enter the cell and cause infection.

Sweet and simple.

3/n
The aim of vaccines is to try and prevent infection in your body.

Hence, most of the vaccines are targeting the Spike Protein (nutty spikes).

Scientists sequenced the RNA of the virus and identified the genes making the Spike Protein.

Let's see some vaccines now.

4/n
➡️Imagine if someone took away all taste and flavour of Ferrero Rocher. It is now lifeless, tasteless.

That's COVAXIN.

They killed the SARS-CoV-2 virus, took away its ability to cause infection. Body can still identify it and mount an immune response against it.

5/n
COVAXIN has been developed by Bharat Biotech.

It is the only vaccine in use right now that uses an inactivated virus.

All the other vaccines we'll see below - target only the Spike Protein (nutty spikes).

6/n
➡️What if I use the crunchy nuts of Ferrero in another chocolate? Maybe Snickers?😋

That's COVISHIELD.

The genes making the Spike protein are mixed into an adenovirus that can't cause infection in humans. It makes the Spike Protein in our body.

7/n
The vaccines SPUTNIK V and JANSSEN are similar to COVISHIELD.

COVISHIELD uses a Chimpanzee Adenovirus.

SPUTNIK V and JANSSEN use a Human Adenovirus.

The mechanism is the same - adenovirus is used as a vehicle to send the spike protein gene to our body.

8/n
➡️What if I can somehow teach my own body to make those crunchy Ferrero nuts? 😍

That's mRNA vaccines - Pfizer and Moderna.

The genes making Spike Protein are encoded into an mRNA. mRNA = messenger RNA -> makes proteins in our body. It makes the Spike Protein in our body.

9/n
A similar mechanism is also used by ZyCoVD vaccine by Zydus Cadila.

Instead of mRNA, ZyCoVD uses plasmid DNA (a free-floating piece of DNA) that contains the code for the Spike Protein.

ZyCoVD is still undergoing trials in India.

10/n
➡️What if I just want to eat the ready-made nuts of Ferrero?

That's COVOVAX.

They took the code for the Spike Protein, put it into another virus called baculovirus that infected moth cells. Spike proteins made were collected, made into nanoparticles, and used as vaccine.

11/n
In the simplest of words - they made the spike protein outside the body, in a lab - and then inject it as a vaccine.

COVOVAX is the brand name of the vaccine developed by Novavax, USA, and manufactured in India by Serum Institute - undergoing bridging trials in India.

12/n
Here's an excellent graphical presentation from Reuters that explains the approaches to making vaccines as above.

13/n
So, as you can see from above -

NONE of the vaccines have a complete, living virus that can cause infection.

Covaxin has the killed virus - unable to cause infection.

All others - barely have 1 component of the virus - the Spike Protein.

VACCINES CAN'T CAUSE INFECTION.

14/n
So, all in all, this is how the vaccines in use/undergoing trials work.

They are safe.
They are efficacious.

Get vaccinated when you can.
And, implore others to get vaccinated as well.

😇😇😇

Unfortunately the "This work includes the identification of viral sequences in bat samples, and has resulted in the isolation of three bat SARS-related coronaviruses that are now used as reagents to test therapeutics and vaccines." were BEFORE the


chimeric infectious clone grants were there.https://t.co/DAArwFkz6v is in 2017, Rs4231.
https://t.co/UgXygDjYbW is in 2016, RsSHC014 and RsWIV16.
https://t.co/krO69CsJ94 is in 2013, RsWIV1. notice that this is before the beginning of the project

starting in 2016. Also remember that they told about only 3 isolates/live viruses. RsSHC014 is a live infectious clone that is just as alive as those other "Isolates".

P.D. somehow is able to use funds that he have yet recieved yet, and send results and sequences from late 2019 back in time into 2015,2013 and 2016!

#தினம்_ஒரு_திருவாசகம்
தொல்லை இரும்பிறவிச் சூழும் தளை நீக்கி
அல்லல் அறுத்து ஆனந்தம் ஆக்கியதே – எல்லை
மருவா நெறியளிக்கும் வாதவூர் எங்கோன்
திருவாசகம் என்னும் தேன்

பொருள்:
1.எப்போது ஆரம்பித்தது என அறியப்படமுடியாத தொலை காலமாக (தொல்லை)

2. இருந்து வரும் (இரும்)


3.பிறவிப் பயணத்திலே ஆழ்த்துகின்ற (பிறவி சூழும்)

4.அறியாமையாகிய இடரை (தளை)

5.அகற்றி (நீக்கி),

6.அதன் விளைவால் சுகதுக்கமெனும் துயரங்கள் விலக (அல்லல் அறுத்து),

7.முழுநிறைவாய்த் தன்னுளே இறைவனை உணர்த்துவதே (ஆனந்த மாக்கியதே),

8.பிறந்து இறக்கும் காலவெளிகளில் (எல்லை)

9.பிணைக்காமல் (மருவா)

10.காக்கும் மெய்யறிவினைத் தருகின்ற (நெறியளிக்கும்),

11.என் தலைவனான மாணிக்க வாசகரின் (வாதவூரெங்கோன்)

12.திருவாசகம் எனும் தேன் (திருவா சகமென்னுந் தேன்)

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.
