A pro-vaxx article that gets into more detail. I don't care for the statement that there are devious intentions in raising the question of why placebo's aren't use much anymore as this is a reasonable question. Whenever you portray the opposing side as sinister, you undermine your own credibility and what tends to follow is a lightweight argument. Nevertheless, there are worthy details here; although much of it is propaganda. By that I mean it has the usual fixation on the polio vaccine of 70 years ago (it's not so simple and the industry has become corrupted since then) and the Danish study on MMR.
Excerpt:
Some of the misinformation regarding vaccines includes an argument that vaccines have not been tested against a saline placebo in a double-blinded randomized clinical trial. This misinformation is aimed at confusing the wealth of evidence regarding the safety and effectiveness of immunizations. In this blog post, we will explain what a blinded randomized clinical trial is, when this study design has been used in the development of immunizations, and why it is not used as often anymore.
What Is a Randomized Clinical Trial?
First, we need to understand what goes into running a double-blinded randomized clinical trial (RCT). In such a trial the group of participants is randomly assigned into either a control group or an experimental group. This assignment is completely at random, and the people going into either group are not aware of what group they’re in. The researchers also do not know what group the participants are. The intention behind this is to obtain experimental and control groups that are similar to each other in every way, such as age, gender or ethnicity.
