    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: https://sites.google.com/view/sources-vaccines


    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.

                                      You forgot the most serious side effect of vaccines. And YES. This is confirmed by studies. Vaccines DO increase the risk of this effect.




                                      It's called overpopulation, and it's only gotten worse since humans started developing vaccines.

                                                    I take my kids to the doctor so they can vaccinate them instead.

                                                            I still want to see the sources of this people, just for shit and giggles you know?

                                                            Not much of one really.  lol!  When all we see are anti-vaccine proponents all parroting what amounts to the same pseudo-scientific and conspiracy theory claims they got from their "friends" in the echo chambers they create for themselves on social media then it requires little effort to expose and debunk such claims.  It is the intellectual equivalent of placating a restless child via some diversion = little brainpower involved.  Have a nice day.

                                                          What happens if we just injected memory cells of the disease from health people?

                                                            To add to what others have noted I would also point out the expense involved.  It would be considerably more expensive to either obtain such cells via blood draws and/or grow in a laboratory actual cells to administer to someone.  Meanwhile cells such as with when someone receives blood products etc. are usually given IV = even more invasive than a shot. 

                                                            So it is cheaper and easier to simply grow bacteria and viruses and separate out the parts we need or else to attenuate them for use in vaccines.  Huge amounts can easily be grown in some medium after which the parts we need are simply separated out and there is little fear of rejection.  Have a nice day.

                                                            I asume that Since they are not memory cells that our body created , our body would think those cells are viruses/bacterias and just try to kill then
