    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.

      I am constantly being called an "anti-vaxxer" and a "science denialist" just for pointing out that it's a bad idea to allow governments make sticking needles in your children mandatory. They also called me a "conspiracy theorist" for pointing out that some vaccines used mercury compounds as preservatives.

            Thank you SQUACK = for demonstrating how anti-vaxxer trolls have no idea of what they claim online as others have noted.  Now it's time for a reality break. 

            1 - vaccines undergo rigorous testing via clinical trials per international standards for biological research in human test subjects.  They further undergo after licensure post-marketing surveillance to identify any potential issues which had not manifested in the previous phases of clinical trials.  Lastly in the US there is the VAERS system which also is available for people to record reactions to vaccines.
            2 - because vaccine production is so regulated, comes with high production cost overhead, and vaccines come with low reimbursement since their primary customer are governments who set the prices they will pay by law = only a handful of pharmaceutical companies even bother to make them.  Were it otherwise then we should see lots of companies churning out vaccines per the law of the marketplace..........yet we do not.
            3 - clinical trials as noted identify possible side effects from vaccines.  Therefore when those vaccines are sold to the government who creates the vaccine schedules and who distributes them for administration = the government becomes the "end user" and as such accepts responsibility for any adverse reactions occurring which were previously identified as being possible prior to licensure.  In other words they purchase the vaccines understanding that some people might not react well to using them.  Accordingly they created the VICP to deal with that eventuality.

            Moral of the story:  it's easy to spout hysteria and conspiracy theories online as we see............but citing actual facts is another story altogether.  Vaccine makers are not immune.  If one fails to abide by applicable regulations governing production of vaccines to turn out a defective product = they can be liable to civil suits.  Meanwhile as noted the government accepts responsibility at the time of sale for known possible side effects.  Better luck next time.

                              I think the saddest part of the whole anti-vax b/s is they not only have no idea how vaccines work, they also lack even fundamental knowledge of what autism is. It's like 2 different schools of ignorance had a baby (that immediately died of measles).

                                            No. Sorry but cancer is a mutation in your cells making them multiply uncontrollably so you cannot be immune.

                                            Partially correct Ashley.  You are correct in that cancer represents an idiopathic aberration with your cellular makeup rather than an external pathogen as with infectious diseases.  Yet your body periodically produces aberrant cells as a normal byproduct of the cellular mitosis which drives our bodies.

                                            Your immune system will usually identify these defective cells and instruct them to commit "suicide" via apoptosis.  When that system breaks down however = we see tumors and cancer result.  So cancer represents a dysfunctional immune system and accordingly there is nothing to "learn".  All we can do is to try to destroy those aberrant cells externally via things like chemo or radiation and hope the immune system will kick in to do the rest. 

                                            Moral of the story:  because it failed to do it's job to begin with = it can similarly fail again.  That is why we sometimes see reoccurrence after a time or else cancers affecting other systems.   Something is amiss with the body which it can not overcome = making it subjective to the individual alone.  We can prevent measles because it's cause is a single known virus.  Cancers on the other hand can be the result of multiple etiologies making them difficult to pin down.  Have a nice day.

                                            Cancer is a little different. Cancer is a mutation from cells already inside your body so its nothing you contract. Your body may learn from previous cancer, but cancer cells are much harder to destroy

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

Of course it is not true as measles still kills worldwide each year tens of thousands of people = last stat I saw some time back was around 90K.  Meanwhile the chances of death from the MMR are actually extremely low = extremely low.  Better luck next time.
