    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.

      The fact you brought up Wakefield's "research" just proved you didn't actually look into it at all. That's a fact.

        To many antivaxxers dont realize how bad these diseases are. I've herd stories from my grandmother about kids with polio when she was young, and how scary it was you could be next in the hospital with an iron lung.

            I sorta am half in half out. I've been vaccinated but at the same time I havent been vaccinated in everything. Now please don't kill me, but I do believe that some vaccines are lethal and unnecessary. But vaccines that are necessary obviously are needed. So yea if u wanna get vaccinated just think if it's unnecessary or not

                                              incativated vaccines are proven to work. In the EU there is currently a measles outbreak and it’s only getting worse because you anti-vaccine fuck heads don’t do any research whatsoever and only argue with feelings. Unless you can send me a link to an article that proves vaccines don’t work and do more harm, than good I won’t change my mind.

When it comes to autism in tons of cases can be directly linked to specific shots required in the states! Video proof of children being outgoing normal children to non moving huge signs of autism directly after shots. It’s 2019 we all have tons of videos of our child now! All hit very high temperatures after vaccine then completely different child within 24 hours. Fact is you know nothing of what the government does outside of your books!!

From my experience, it hurts the most when you tense your muscles, so try to stay calm. If you relax, it’s not that bad.
