There are various types of corona vaccines that have existed in the world today. So, what's the difference between these vaccines? Are some stronger than others? Or are they all the same? To answer all these questions, let's take a look at my article.

For my article, we will discuss five different types of corona vaccines, namely: Vaccines from Pfizer-BioNTech, Moderna, AstraZeneca-Oxford, Sputnik V, and Sinovac.

There are a number of differences between these corona vaccines. The biggest difference between the two is the difference based on how they work. Well, for my article, it is the differences that we will discuss. But before discussing the differences in how vaccines work, it is better if we first understand how the human body actually fights against viruses and creates immunity.

When a virus or foreign object enters the human body, our immune system will attack it. However, the process of the immune system getting rid of the virus takes a long time, because to beat an infection in the immune system we have to figure out how to fight it first.

While this process continues, the virus will continue to spread and multiply, and the infected body will get sick. Finally, after the body's immune system has successfully eradicated the virus, it will keep on remembering how to fight it, so that if the same virus comes again, our bodies are ready to deal with it.

So basically it can be said that all vaccines work relatively the same. Namely to provide our immune system with a strategy to fight viruses without having to fight the virus directly. However, the way this resistance strategy is delivered is different for each vaccine.

Here are 5 differences in Corona Vaccines

1. Sinovac

We started with Sinovac, the COVID-19 vaccine made in China, which uses the Inactivated Virus method. This method uses the COVID-19 virus that has been killed, which is then inserted into the human body. Even if it is inactive and unable to spread, the immune system will still respond and learn how to fight it. However, the response from the immune system may not be as effective as against live viruses. Therefore, this type of vaccine requires several doses to be effective.

2. AstraZeneca-Oxford and 3. Sputnik V

Furthermore, there are vaccines from AstraZeneca and Sputnik V that use the Viral Vector method. Unlike the inactivated virus method, this method uses viruses that are still alive but relatively weak, such as adenoviruses that cause colds. This weak virus is then used to lift the genetic material of COVID-19, which the immune system will use to create immunity without exposing the body to the true dangers of the corona virus.

4. Pfizer-BioNTech and 5. Moderna

Furthermore, the most discussed method, and the newest of the existing vaccines, is the mRNA vaccine used by Pfizer and Moderna.

The way this vaccine works is pretty cool, so read it carefully. In COVID-19 there is a very important protein. This protein is used by COVID to enter the cells of the human body, making them more infectious. Think of it as a weapon that makes COVID too overpowered. So, logically, if we can make the body immune to this protein, then the body will be immune to COVID-19 as a whole.

What vaccine researchers are doing is taking the piece of COVID DNA that contains the blueprint for this protein, and then converting that blueprint into instructions for the body's cells to make the protein, these instructions are known as mRNA, and this mRNA is the vaccine. .

Then, why do we want the body's cells to make this protein? Isn't that dangerous? Not at all, this mRNA is safe because it only contains instructions for making protein, and does not contain the complete Corona virus.

So it can be considered like a weapon without a master. After mRNA enters the body, the body's cells will start making this protein, which the immune system will then respond to. After the immune system has successfully destroyed this protein, it will remember how to fight it, thus making you immune to COVID-19.

Closing

Ultimately, my article is not meant to persuade you to choose a vaccine. Because for most people, which vaccine we get is out of our control. What you need to know is, the vaccine that is now being prepared for mass use has gone through an intensive testing phase to maintain its safety and effectiveness.

And the fact that we were able to get so many vaccines in the fastest time in human history is already a bright side to a very dark year.

Surely all of this has been made possible thanks to the thousands of medical personnel, scientists and researchers who have worked non-stop since the pandemic began. And now the rest is in your hands.

That's all for my article this time. If you could choose, which brand of vaccine would you use?
