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.

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.

So in the past they poisoned us with dangerous mercury and more aluminium? So you have admitted their guilt. They are still poisoning us. Even more. Or is it just that they stay one step ahead of popular scientific knowledge. Should we trust Big Pharma and it's links to the Nazis etc. Read the book Bad Pharma. Who pays to produce these cartoons? Yes - there are bad and crazy people in power at the highest levels who instead of toothbrush moustaches have cultural ways to indoctrinate. Listen to experts, because simplified explanation can be deceiving.
Mercury and aluminium, and things like flouride, which is also a known brain toxin which is in our daily water (first added in the concentration camps to make the prisoners docile) and toothpaste have precursors...building blocks...
chemicals which contribute towards their formation. 1+1=2.
We are talking also about about injecting new born babies with many, many weird things at the same time, including viruses or parts of viruses when their immune systems are not developed so again we are talking about the combined effect of these things. If the anti-vaccine lobby is not a dumb fashion then it's arguments are worth investigating. I am not scientist but there are many scientists on that side or at least with many serious issues to raise and if more were paid by the state or Big Pharma then there would be more. The burden of proof is on the person who wants to inject millions of why is it so often the sceptics who are having to justify their position? Because many simplly believe in authority. Be careful with that. The say nuclear power is safe but look what happened in Chernobyl or Fukushima. Science is good but as it is driven by finance and investors and maybe people who belong to an elite who want to reduce the population, we have to be more than happy shoppers.
The issue about many african countries going to court over masses of tetanus viruses containing sterilisation agents is common knowledge among well-informed people. So it depends what sources are official.
But then again, ask your doctor about cancer?
It is now becoming clear that Cancer is often triggered by "harmless" viruses....and one day it will be common sense will catch up and say that it is logical. Meanwhile people are dying and the cancer industry is lagging behind the facts. Perhaps because if people can help prevent cancer by common anti-virals such as cat's claw and raw garlic then why do doctors never prescribe natural preventative medicine to their patients?
Why do schools not provide a few pieces of fruit free for every child?

@Noob_Frvr 676 Please do some real research before believing this video. We are destroying our children. A baby is designed to have no inflammation the 1st year of life. The baby is developing it's immune system and the mothers breast milk is providing immunity. We proceed in the USA to give the precious unformed immune system of an infant 24 doses of vaccines the first year of life in fact we give the hepatitis B vaccine the 1st day of life which has 10 times the recommended amount of aluminum according to the weight and the FDA guidelines. Aluminum creates an antibody response which creates inflammation in the 1st day of life. The USA has the highest infant mortality in the developed world right now. We are three times Japan which gives no vaccines the 1st year of life. Maybe our CDC FDA and HHS are being bought off by big money. Pharma, Government agencies, media and politicians are all in bed. Good luck getting any real science.

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

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

Fake video. Vaccines cause more deaths than measles worldwide
Vary Olla
Vary Olla - 6 timmar sedan
Of course they do not Noob. lol! On a side note what "as" referred to would ultimately be oxymoronic for the following reason. The MeV only infects humans much the same as the Variola virus which caused smallpox did. Accordingly since humans are it's only host = by the time potential deaths from administering the MMR outnumbered actual deaths by measles the disease would all but be eradicated...........thereby eliminating the need for the measles vaccine to be administered. As such it represents a self-correcting problem as such vaccine deaths would then no longer be possible as vaccine employment would cease as it has for widespread smallpox vaccination when it too was declared eradicated long ago. Have a nice day.

That then as = would a beautiful thing. That would mean that vaccines had reduced the incidence of measles sooooooooo low = that those rare severe reactions to the MMR then outnumbered actual deaths by measles. 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.

Wait isn't autism linked to genetics? Idk tho I'm 15
Vary Olla
Vary Olla - Dag sedan
Yes Epic. Children are born autistic as a result of something in their genetic makeup results in neurocognitive deficits. Unless those deficits are severe in nature however = an autistic child will not usually manifest signs of that autism until a latter point in their lives as their brains are still developing. This is what I mean. Human children are born with the capacity for language and movement. Yet a newborn can not immediately speak anymore than it can get up and walk or run like say a baby gazelle. That is because it's brain is still developing those capabilities. So it will coo and grasp at it's feet at first ---------> then it will roll around on the floor and attempt to crawl = and eventually it will make sounds and try to stand and then walk. Likewise a doctor will usually wait until 12 months or later to assess an infant for neurocognitive deficits because the child can not tell us what it is feeling while the doctor can not accurately gage some capacities absent that verbal interaction. Meanwhile vaccinations sometimes overlap this timeframe. Accordingly some parents will conflate a diagnosis of autism with the timing of those vaccines as causing it = wrong. Lastly is after the fact neurological damage which results in "autism-like" behaviors. Before there was an MMR each year in the US we used to see thousands of children hospitalized with encephalitis from catching measles. Today while it is possible for the MMR to cause encephalitis = thankfully that is a rare occurrence. Because both the vaccine and the disease cause the same problem = the virus and not the vaccine per se is responsible. So a child who receives the MMR and develops encephalitis which causes some neurological damage resulting in autism-like behavior would be no different than say a child who received perhaps a blow to the head from a baseball bat and who suffered brain damage as a result which precipitated autism-like behaviors. Do baseball bats then cause autism = of course not. Rather such a child is reflective of those we used to see anyways in the time before the MMR who could not tolerate exposure to measles and who reacted harshly as a result. Most often those children who react badly to being vaccinated = have some underlying health issue which is driving the reaction since almost all children vaccinated do not react as such. That makes the preexisting health issue responsible and not the vaccine as absent it = the child would not have reacted as they did to the vaccine. Have a nice day.
