so how many of us remember the first time we were shot I don't mean by a gun I mean by that our first shot right our very first vaccine and I remember being at the doctor's office as a child and going in and being vaccinated just thinking is the worst thing in the world ever because it hurts so much and then I learned what vaccines are and it was really helpful for me so let's talk about that together so I have two images here and let's get rid of that needle because it's pretty scary so I have one of the influenza vaccine labeled flu and one of the pneumococcal vaccine labeled pneumo now and we're talking about the flu vaccine we know that the flu vaccine is going to protect us against the influenza virus oops there's Mayu influenza virus and we know that getting the flu is a pretty crummy thing now we know that the flu vaccine can protect us against three or four different serotypes so what does that mean so the flu vaccine comes in a trivalent let me change my color here or a quadrivalent and what does that mean so if you had a trivalent vaccine it's going to protect you against three different serotypes of the flu and serotypes really means strains right so different types whereas the quadrivalent can protect you against four different strains or serotypes of the flu and that's really important with this type of vaccine in this type of virus because we know that the flu vaccine changes on a yearly basis and it's important that we're able to keep up with it and protect individual against the most appropriate stream and so how does that work when I say the influenza virus changes it really does so let's say that one year and we'll say this was 2012 that the flu vaccine excuse me that the flu virus looked like this and then let's say that the next year the flu virus looked like this and then let's say that in another year it looked like this so you see that it changes a little bit every single year and that's why it's important that research and data are able to look at all these changes and to figure out what the most likely virus is going to be this year to protect us against it now just like we have a flu vaccine that protects us against three serotypes or for our pneumococcal vaccines pretty similar in that we have vaccines that can protect us from anywhere from 7 to 23 different strains and that's pretty important too now if you notice in the name the pneumococcal looks like pneumonia and it should because pneumococcal diseases actually cause things like pneumonia and ear infections and meningitis all the things that we don't want to get it protect us against the pneumococci bacteria so I'm gonna go ahead and write pneumococcal so we know what we're dealing with now what do we have to know about these vaccines these are inactivated vaccines so what that means is that it's essentially the killed virus so if we come over here I'm going to draw a picture and let's say that this is the influenza virus so I'm gonna just make it round like this and then I'm gonna put some green squiggly shell on the outside now I want to draw it like this so you can see something so I thought that this flu vaccine is inactivated that means that it's killed so what we do is we actually destroy the virus so destroy the pathogen just showing what causes the infection what causes all those bad symptoms but I'm gonna leave that protein shell intact and I'm gonna leave it intact in the vaccine for a reason I want the body to recognize this as a foreign invader and build up a defense to it so how does that work let's scroll down here now I'm just gonna draw a blood vessel now remember that syringe that we saw earlier that's scary syringe let's say that that scary syringe had this flu vaccine in it so it's gonna have this protein shell so I'm going to draw this tene shell here in the body now what's gonna happen it's been introduced into me through that that scary needle right now my white blood cells are gonna show up to the scene and we know my white blood cells these are my security guards right this is my defense system they're gonna protect me against anything that's coming to hurt me in this case my white blood cells recognize that this guy right here doesn't belong and so what are they going to do they're going to attack so my white blood cells are going to reach out and they're going to beat up or they're gonna attack this foreign invader now because this is an inactivated vaccine that it's not really the flu virus it's just the protein shell it's not enough to make me sick it is enough that my body recognizes it shouldn't be there and it's going to beat it up like we said right it's gonna attack it going to destroy it and it's gonna remember and put in there it's imaginary pocket it's gonna put in a picture of this flu this flu virus that way it's gonna remember if this virus ever shows up again I know how to beat you now because it's still part of the virus because it still has a protein shell there's a small chance that it could manifest in us some very very mild symptoms of the illness but it's not enough to make us sick now who benefits from vaccines really anybody but especially individuals that have lung disease so let's just draw our lungs here so especially someone that has got chronic lung disease like chronic obstructive pulmonary disease somebody that has emphysema and the reason why they benefit from these vaccines is because they're more likely to get the disease and they're less likely to be able to fight it off on their own and then finally I'll end with this last thing we have something called a vaccine information statement and sometimes you might see it called B is so vaccine information statement and this is really a piece of paper that we give to our patients and you see that I just am writing flu and pneumo on here and what it is is this sheet that has information about the vaccine so that the patients are aware of everything about it what it how it's made what it's used for and that way they're clear on the vaccine that they're receiving
