As covert nineteen spreads from the corona virus pandemic many are doing their part by social distancing and self isolating but as the virus and disease progress one big question on many people's minds is what can we expect with regards to a vaccine? So there are a ton of fascinating things happening right now and tireless research looking into a vaccine but in order to understand it we must first talk about how vaccines work? It was in the year seventeen ninety six of the first official vaccine was created by Edward Jenner, he took a bit of a discount pox virus and injected into a small bowl he later was able to confirm that that boy did not develop smallpox which was a related virus so how exactly did this work typically when you get infected with the virus? It begins taking over yourselves machinery in order to make copies of itself but these actions eventually trigger an immune response your body begins creating special cells like macrophages B. cells and T. cells that not only try and destroy the pathogen also store information about it what it looks like the best way to defeat it and more this part is especially important because of the virus ever comes back again your body can be immediately prepared to attack. It but the body takes time to do all of this and so if a virus gets enough of head start or tax somebody with a compromised immune system it can gain the upper hand leading to illness or death.
This is where vaccines come in there are many different types. The main goal of the all is to prepare and train your immune system before you get an infection. it's like a practice run that way when your body is invaded by the real virus. it has an advantage because it already knows how to take down the invaders ! Most vaccines work by injecting some aspect of a virus or bacteria into your bloodstream. All depends on what strain you're trying to protect against? We're gonna focus on viruses today once administered into the bloodstream even though it's not the real virus the body reacts as though it's a real threat macrophages engulf the pieces allowing T. cells to recognize and bind the foreign antigen because.
The effectiveness of vaccines has allowed us to nearly a radical hate diseases like measles. Of course that recent vaccine hesitant movement in which it kind of came back regardless they are extremely powerful tools to provide immunity to the individual and to protect larger communities and in our ever connected world. Your body which are very effective but can't be given to people with compromised immune systems. Active vaccines like polio or hepatitis A. use dead pathogens that have been killed by heat or chemicals these can be used on people with already weakened immune systems however they aren't great for long lasting immunity because they don't stimulate the real thing quite as well as live attenuated vaccines and often require several doses sub-unit vaccines like hepatitis B. or influenza use a specific protein or carbohydrate from the pathogen that will still trigger an immune response . There are some other experimental DNA vaccines but perhaps the most relevant is a promising new technique of vaccines called M. RNA vaccines which you may have heard about recently that's because they are currently in development and have begun testing on humans to potentially fight the spread of covert nineteen.
