Vaccines 101: How vaccines work

As the world waits for a potential COVID-19 vaccine, we delve into how vaccines actually work. What are the different types of vaccine? How do they trigger and train the immune system, and what is the role of herd immunity?

If your teacher made you watch this video

It is simply crazy to think our body is structured like a military defense system and how adaptive immune system can adapt to defend against foreign particles. I also, learned how there's diverse types of vaccines and not just one type. It is amazing to think people made these kinds of defenses for our body.

In this video, we should take the knowledge that vaccines are provided for a reason. Vaccine protect and attack any pathogens in our body. This is how the COVID19 vaccine works.

With such a large part of the population refusing to take a vaccine when (or if) it becomes available in the US, herd immunity is not feasible.

WRONG! MY 4 KIDS HAVEN'T HAD VACCINES EVER AND THEY ARE FINE!

Edit: 3 kids

I had no clue how complex and different forms a vaccine can come in. There’s advantages and disadvantages to live attenuated vaccines, simulants and others that weren’t talked about. Simulant is effective, but is not necessarily something that is good for the long term. I feel now that I'm more knowledgeable on how vaccines work, I'm more open to getting the vaccine.
