Since we're all going to be vaccinated soon (some against their will), it is only proper that we understand what vaccines are, what they do and how they do it.

Firstly, the fundamental differences between 'traditional' vaccines and the new COVID-19 vaccines...

[Thread]
According to the World Health Organisation, vaccines work by training the immune system to recognize and fight pathogens, either viruses or bacteria. To do this, 'inactive' molecules (pieces) of a virus (antigens) are introduced into the body to stimulate an immune reaction
As per the WHO, the inactive version of a virus will not cause disease in the recipient, but will only cause the immune system to respond as it would have if it came into contact with the actual pathogen
Now the body is trained to fight the specific virus, developing 'memory' of this pathogen so as to rapidly react to and fight it if and when exposed to it in future. According to the WHO, "If you are able to, get vaccinated". It is not mandatory, it never has been
Now the COVID-19 vaccines are different. According to the United States Center for Disease Control, there are 3 types of COVID-19 vaccines undergoing large-scale clinical trials in the U.S: mRNA; Protein subunit and Vector vaccines. In reality, the mRNAs are the only game in town
How an mRNA vaccine works is it injects molecules of synthetic genetic material from non-human sources into the body's cells. From there this genetic material interacts with the cell's transfer RNA to make a foreign protein that 'teaches' the body to destroy the target virus
These newly created foreign proteins are NOT REGULATED BY THE BODY'S DNA, and are thus completely foreign to our cells. It is not yet known what they can really do, in the medium and long-term at least
The body naturally destroys foreign material introduced into the cells, and the mRNA molecule (synthetic foreign genetic material) is very fragile. So to protect it, manufacturers coat the mRNA with nanoparticles known to to induce allergies and autoimmune diseases
In any case, South Africa is likely to receive the Oxford-AstraZeneca vaccine, which unlike other mRNA vaccines, which store instructions in single-stranded RNA, the Oxford vaccine uses double-stranded DNA to introduce genetic material into the body's cells
In addition to how it stores the coronavirus’s genetic instructions, the Oxford-AstraZeneca vaccine is coated with a virus called an adenovirus which induces colds or flu-like symptoms. In this case a modified version of a chimpanzee adenovirus was used
The Oxford-AstraZeneca vaccine for Covid-19 is more durable than the other mRNA vaccines because DNA is more rugged than RNA, plus the chimpanzee-derived adenovirus’ tough coating protects the genetic material inside
The Oxford-AstraZeneca vaccine doesn’t have to stay frozen and is expected to last for at least 6 months when refrigerated at 2–8°C. This is how they say it works:
When the vaccine (virus) is injected into a person, the chimpanzee adenoviruses cling onto protein on the cells' surface. The cells then wrap the virus in a bubble and pull it inside. Then the adenovirus escapes from the bubble and travels to where the DNA is: in the nucleus...
The chimpanzee-derived adenovirus now pushes its DNA into the cell's nucleus (N.B!). The coronavirus genetic material can now be read the cell and copied into mRNA (which by the way stands for messenger Ribose Nucleic Acid)
The mRNA leaves the nucleus. The cell reads the mRNA sequence and begins producing proteins with spikes which move from inside the cell and onto the surface and stick their tips out. These tips alarm the immune system (they're coronavirus protein spikes afterall)...
Immune cells called B-cells, bump into the coronavirus spikes on the surface of vaccinated cells. Some of these cling onto the spiked proteins. If these B-cells are then activated by immune system T-cells, they multiply and release antibodies targeting the spike protein
As a practice drill , the antibodies latch onto coronavirus spikes and prevent infection by blocking the spikes from attaching to other cells. Killer T-cells may now be dispatched to seek out and destroy any coronavirus-infected cells that display the spike protein fragments
All of this sounds nice, except in testing, this vaccine was found to only have 62% efficacy at 2 full doses (the human immune system has a 99.7% success rate against COVID-19, minus the aluminium, mercury, and maybe formaldehyde and some side effects)
White House health advisor Dr. Anthony Fauci to the Senate Committee on Health, Education, Labor and Pensions : "There’s no guarantee that the vaccine is actually going to be effective"
Another thing, the face panties stay on after you get vaccinated, logically this means church, groove and football stay closed too, because common sense. Thing is, "it’s unclear if vaccinated people could be asymptomatic and still spread the virus to others"...
"We don’t actually know whether (the vaccines) prevent somebody from becoming infected and then spreading it forward" - an American doctor

Apparently what these high tech vaccines do is help you not get too sick WHEN you get infected. Sort of like... umhlonyane and shid. Skrr!
