Wikipedia: The healthy user bias is a bias that can damage the validity of epidemiologic studies testing the efficacy of particular therapies or interventions. Specifically, it is a sampling bias: the kind of subjects that voluntarily enroll in a clinical trial and actually follow the experimental regimen are not representative of the general population. They can be expected, on average, to be healthier
Healthy User Bias FLAW does apply to the MMR-Autism Study.
Parents who VOLUNTARILY use Vaccines are MORE LIKELY to have children who are developing Normally.
Parents who have a Child who is showing SIGNS OF AUTISM are more likely NOT to give the MMR – which
is given at 12-15 months.
By 12-15 Months, the child was already INJECTED with 3,675 mcg of ALUMINUM and is showing signs of Vaccine Damage.
So there may be MORE children with Autism in the PARTIALLY VAXXED who did not get MMR.
Because the giving of MMR was NOT RANDOM but HEALTHY USERS (normal children) got MMR
While those already Vaccine INJURED avoided the MMR!
If there is anyone out there who don’t Worship Vaccines who understands why Healthy User Bias makes
the CDC Vaccine Safety Studies INVALID, please join in!
