better confidence in the results is to remove the doctors ability to know if they are administering the medication or not. It was found out that if the doctors knew what they were administering (placebo or medicine) they would rig the result and not be truly “double blind” - reducing the efficacy of the trials.

The “Right to Treatment” laws that have cropped up for early trial experimental treatments actually harm the outcomes of the trials and certainty of treatment.

So, vaccines have withstood all of these challenges with testing and certainty are absolutely the best thing for your child.
