The Side Effects of Vaccines - How High is the Risk?

  • Published: 12 May 2019

    Vaccines are one of our best tools to prevent dangerous diseases, but they come with side effects. So would it be safer not to vaccinate?

  • Kurzgesagt – In a Nutshell

    Dive into sources and further reading here:

    Vaccines and their side effects are a hard topic to cover – we know we keep saying this, but this case especially, there were a lot of things to consider. You can’t blame people for being worried, so we wanted to take their concerns seriously.

    Because it is impossible to cover everything there is to know about vaccines in a ten minute video our sources are extra extensive and explain a lot of aspects in more detail, with an extra focus on further reading.

    So if you want to dive in deeper or have more arguments at hand for your next heated discussion, here you go.

      It would be nice if you had touched upon, or at least mentioned that we vaccinate against a multitude of other diseases besides measles.

                Are Kurzgesagt Avengers fans? This may be a coincidence, but at 4:54 the top left is labeled "Earth #199999", which is the original universe number assigned to the Marvel Cinematic Universe. And, at the same time, the top right has an airship that resembles the Helicarrier. I don't know if this was intentional, but it's a cool easter egg if so.

                Edit: This was definitely intentional, I just noticed that Stark/Avengers Tower is in the center of the large city. Way to go guys!

                            How about the chemical plant on the edge of town? Antivaxers should worry about how companies dispose of waste, fix spills, etc. Lots of towns in rural southern USA have birth defects, high cancer rates, etc

                              for most of human history it was completely normal and expected to have 5 to 7 kids and see 3 to 4 of them die before they reach the age of five.

                                      Well... I have an idea... Don't prove vaccines are good... Let's find why children's with autism and ADHD and mental health issues growingly rapidly in this modern vaccinated society why a 12 years kid suffers from depression anxiety and mental health issues.... And the number of children are rising ... And show me what can go wrong in making a vaccine not just how it's made..... Apart, what can go wrong that they have to put poisonous substances in a vaccine...

                                        1) Those rates are going up because we're better at diagnosing them. There's not much evidence that suggests that the rates are actually going up, and even if they are are, there's little linking it to vaccines. 2) Have you ever thought as to why biochemists put those 'dangerous' elements in vaccines? Hint: it's not for their minty flavor. There's a reason for everything that goes into a vaccine.

                                      Not much risk,very high rewards. Good day, goodbye, if you dont get your vaccines for any other reasons than "i have been diagnosed with death if I come into contact with any of this", then you can get the fuck out.

                                                                Because those cells have to be created by each individual's own immune system. If you were to somehow clone memory cells from another individual and inject them into someone else, it would be recognized as foreign by the host immune system and destroyed. It's the same reason that organ transplant patients have to be on immunosuppressents for the remainder of their lives after transplant. Otherwise, the host immune system will recognize the tranplanted organ as foreign and the body with reject (attack) it.

                                                                      arguments to get them to dose their kids. This will not convince an antivaxer. Too smart. Nice try with the British accent but same ignorant argument. It is getting old.
                                                                      Be honest vaccines for nonlethal diseases were about productivity.
                                                                      Imagine a wartime airplane factory's workforce catching meals at same time. Or a farmer with a week to harvest but 2/3 of his pickers are sick for a week? Not about saving life but removing variables that slow down or stop productivity.

I still vaccinate myself and would vaccinate my kids if I had any. It's just a bit messed up in my opinion. If you don't believe me then go on the internet and do some research for yourself

I almost didn't watch it because I got a cold and don't feel like arguing with anyone, then realized that I could be dead from a cold if I wasn't vaccinated so dived right in expecting the worst. I was pleasantly surprised
