    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.

    the side effect of vaccines? you turn into this strange specimen of humans called adults. This can be both bad and good. The bad part of it is that their lives get a lot harder now that they are adults. The good part is that the immune system is stronger and the life expectancy sky rockets.
