How do vaccines work? Let’s Begin...The ﬁrst ever vaccine was created when Edward Jenner, an English physician and scientist, successfully injected small amounts of a cowpox virus into a young boy to protect him from the related (and deadly) smallpox virus. But how does this seemingly counterintuitive process work? Kelwalin Dhanasarnsombut details the science behind vaccines. https://www.youtube.com/watch?v=rb7TVW77ZCs Transcription of TED Talk: In 1796, the scientist Edward Jenner injected material from a cow pox virus into an eight-year- old boy with a hunch that this would provide the protection needed to save people from deadly outbreaks of the related smallpox virus. It was a success. The eight-year-old was inoculated against the disease, and this become the ﬁrst every vaccine. But why did it work? To understand how vaccines function, we need to know how the immune system defends us against contagious diseases in the ﬁrst place. When foreign microbes invade us, the immune system triggers a series of responses in an attempt to identify and remove them from our bodies. The signs that this immune response is working are the coughing, sneezing, inﬂammation, and fever we experience which work to trap, deter, and rid the body of threatening things, like TeenagePixelGunner
