What would a vaccine have to contain to protect a patient from chicken pox? Explain why we don't have vaccines for HIV.

Accepted Answer

Hello everyone and welcome to today's video. So how does vaccination with a weekend varies. L. A. Virus or chickenpox help us to avoid contracting chicken pox. Well, the way vaccines work is that they're going to continue a very small amount of the virus. That is not enough to hurt this. Well, this virus is going to enter our bodies and it's going to trigger an immune response which is going to result in the creation of antibodies that will degrade the virus in the vaccine once it enters our bodies. Now, what is going to happen after this is that our immune response is going to store information about this virus as instructions in what we call memory cells. So whenever we see this virus again, because we already created the antibodies and we already identified it, we're going to be able to fight it much faster and efficiently. Let's go over each of our answer choices so that we may solve this problem. Not doing this. Beginning by answer choice. They introduce weakened virus can compete with another chicken pox virus in terms of nutrients. This is not what we're seeing in these explanations. So we're going to cancel it out. Then we have the introduced virus can cause the weakening of the incoming chicken pox virus. Well, the virus is not weakening the future virus. It is rather providing us with information that we can then use to combat incoming virus. However, it doesn't affect their strength. So we're going to cancel this out. Then we have see the weakened virus can produce enzymes that can degrade another chicken pox virus. Well, the actual virus is not producing these proteins or these enzymes. So we're going to cancel this out and they all left with answer choice, The weakened virus stimulate the immune system to produce antibodies, which is what we're seeing here. This is the immune response, which will then serve as instructions for future viruses and will help us avoid contracting chickenpox. I really hope this video helped you and I hope to see you On the next one.
