Covid Vaccine Is Literally Like Injecting A Line Of Code Into Our Body, And Just Wow.
Like it or not, we’ll probably be vaccinated against Covid-19 sooner or later. I was pretty skeptical at first, but ever since stumbling upon this thread on twitter, I’m awed.
The mRNA vaccines (Pfizer and Moderna) are kind of brilliant at a science level. I’ve had a few people in my real non-Twitter life ask me to explain how it works so I’m going to try my best here in this thread while I’m waiting for a patient to show. — WheatNOil (@WheatNOil) December 17, 2020
This physician from the University of Saskatchewan managed to explain it so simply, yet not undermine the brilliance behind the science of the Covid-19 vaccine.
Firstly, we have to understand how our body’s immune system works. The immune system attacks any foreign matter in our body, such as virus, bacteria or a protein. Every time it encounters something new, it will figure out exactly which part of the foreign matter to attack, what it needs to produce to attack it, and when it’s done it will commit all this to memory so that the body knows what to do should the same thing enter the body again.
Next, we have to understand what is DNA and RNA. DNA is the blueprint to make things in a cell, while RNA is the instructions that tell the cell what to make. mRNA, which is literally messenger-RNA, instructs the cells to make something.
When scientists were looking at the Covid virus, they found a protein on the outside that they thought were perfect for the immune system to launch an attack on. The virus uses this protein to enter our cells and it also makes the virus more infectious. The Covid-19 vaccine was made by taking the RNA (a.k.a. the instructions) of this protein and making an mRNA version of it. When this mRNA is injected, our own cells will start producing this exact protein inside our body. Our immune system will then spot this foreign matter and start an attack against it.
If you really think about it, it’s literally like installing a code into our body. The vaccine does not contain any actual part of the virus, it’s just a set of instructions that tells our body to produce the protein. Of course, the first time this happens the body is going to take some time to process it and fight, which will explain any side effects such as fevers or chills. But there’s nothing to worry about because you weren’t injected with the real virus.
And the most beautiful part is that the memory cells will remember all of this. If in the future an actual Covid virus enters your body, your immune system will recognise this foreign protein and how to destroy it. The mRNA that was injected has also been broken down by our body, like how you eject the installation CD from your laptop once the installation process is complete. You don’t need to reinsert the CD every time you use the software, right?
I don’t know about you, but I’m pretty mindblown by how awesome our body is at protecting itself. Did this knowledge change your perspective of the vaccine?
