Mechanism of COVID vaccine test
The competition for coronavirus vaccines includes mRNA vaccines, which are fast-track candidates developed in the coming months.
The competition continues to develop vaccines that can fight COVID-19.
More than 100 COVID-19 vaccines have been developed by laboratories around the world, and there are many questions about vaccines and their production, especially near the finish line.
After all, finishing this race means saving lives.
With its simplest function, successful vaccines teach the immune system how to fight COVID-19. This prevents COVID-19 from getting sick and spreading to others.
There are many ways vaccines can do this.
Usually, think of something like a flu shot. This includes dead or weakened versions of the virus, tricking the immune system into thinking it is invading and creating protective antibodies.
These antibodies provide our bodies with tools to protect themselves from real viruses when exposed to humans. This is called immunity.

Traditional vaccines usually take more than five years to develop and do not want to live in a pandemic for another five years.
Fortunately, the COVID-19 vaccine competition has the fastest candidate mRNA vaccine developed in the coming months.
It does not contain any viruses. Instead, this vaccine targets cells in your body. In essence, mRNA vaccines are messengers that inform the brain of cells and teach them how to generate their own antibodies to proteins in nucleic acids.
When the coronavirus invades the body, the cells are defensive and ready to destroy it.
I know what the vaccine does, but how do I know if it works?
It is currently in clinical trials, where it is being tested in humans, and there are three stages in the process.
Phase 1: A small number of patients are vaccinated. Scientists check safety, dosage, and whether it stimulates the immune system.
Phase 2: Hundreds more patients will be added to the study. Safety and effectiveness are measured.
Phase 3: If Phase 2 is successful, you can add thousands of patients. This important step tells researchers how many people have been infected compared to those who received placebo.
Throughout all phases, the study is a double-blind study. That is, neither researchers nor patients know whether they are receiving the COVID-19 vaccine or a placebo injection of saline. This helps ensure that the expected response to the vaccine does not distort the results.
Currently, of the dozens of COVID-19 vaccines in the race, only dozens have reached Phase 3. This is promising news, but health officials say that multiple winners are needed to protect the world and save lives.
“There are 8 billion people in the world, and most of these vaccines require two doses. Up to 16 billion doses may be required. In the near future, that amount of single vaccine. We can’t produce vaccines, so we want a lot of vaccines to be effective, so that everyone produces as many vaccines as possible and wants them all. It will be available to people as soon as possible, “said Dr. Bill Smith, a volunteer research group.
Researchers have said that it is impossible and not true about the spread of rumors online that vaccines contain microchips to track us.
