Q: How do vaccines work, in general?
A: Vaccines work by mimicking an infection and training the immune system to recognize SARS-Cov-2 virus.
This training allows the body to respond more rapidly when it encounters the virus in the future.

Q: How do vaccines mimic an infection & train the immune system to recognize the virus?
A: This is usually done by introducing a weakened or inactivated version of the pathogen or parts from it, such as proteins, into the body.

Q: How do mRNA vaccines work?🤔
A: mRNA vaccines take a different approach.
Instead of including a protein from the pathogen or the pathogen itself in the vaccine, they contain the genetic instructions for producing that protein.

Q: What instruction? How?
A: These genetic instructions, known as messenger RNA (ribonucleic acid), are what our cells use as part of the normal machinery to assemble proteins that are needed to keep the cell alive.

Q:What happen when cells receive the instructions?🤔
A:Once the cell receives these genetic instructions, it produces the protein from the virus that can then be used to train the immune system.
The mRNA genetic instructions are DESTROYED by the cell as part of this process

Q: How come we end up having mRNA vaccines? Isn't it much complicated than other vaccines?
A: No!Because mRNA vaccines do not involve any viruses, they can be produced in a facility quicker and cheaper than conventional vaccines that require the viruses to be grown in cells.

Q: What ingredients are in the vaccines?
A: The primary ingredients in Moderna and Pfizer vaccines are the mRNA, lipids, acidity regulators, salts, sucrose (a sugar), and water.

Q: why these compounds are in the vaccine?
A: The lipids is to protect the mRNA until it reaches the cell.
Polyethylene glycol is attached to the lipids to prevent the particles from sticking together and being detected by the immune system.

The acidity regulators, or buffers, keep the pH of the solution at the right level for the body.
The sucrose protects the lipids when they are frozen and prevents them from sticking together.
