I would never say they casue no harm, that is why we have a vaccine damage court and fund. It does happen. It is just so rare. People die from a dentist visit. Are we going to stop going to the dentist, no because we know the benifits far out way the risks.
About never knowing the full range of damage. Here is something from the CDC and the damage courts: According to the CDC, from 2006 to 2015 over 2.8 billion doses of covered vaccines were distributed in the U.S. For petitions filed in this time period, 4,528 petitions were adjudicated by the Court, and of those 2,962 were compensated. This means for every 1 million doses of vaccine that were distributed, 1 individual was compensated.
2.8 billion vaccined in about 10 years. We would see any side effect and the evidence would be over welming. Not just 2,962 payouts.
Most kids who got autism from the vaccines were actually declined by the vaccine court due to loopholes they create; and also you are failing to correlate what I proposed earlier.
->That many side effects and cases of disease caused by vaccines simply go unreported, uncounted or unattributed.
They simply aren't counted in the stats. Intentionally.
If a baby develops encephalitis, they don't attribute it to the vaccine. This causes the numbers to stay very low, even though it's very apparent that the cause of the encephalitis was the vaccine itself. You should watch some videos of parents testimony who have had a child that has been severely affected by vaccine.
You will perhaps then understand what I mean.
Please also have a look at this link and you will begin to see the corruption within the CDC itself to cover up correlation and falsify studies.
