I can not even find one Peer-Reviewed Double Blind Study of any vaccine.
Can you point out some studies for me, if they are available?

That are just a few results from a quick search, there are studies done for every approved vaccine. I'm using the US system as an example, but it will be similar in other countries. In the US the FDA has to approve vaccines:
Pre-marketing (pre-licensure) vaccine clinical trials are typically done in three phases, as is the case for any drug or biologic. Initial human studies, referred to as Phase 1, are safety and immunogenicity studies performed in a small number of closely monitored subjects. Phase 2 studies are dose-ranging studies and may enroll hundreds of subjects. Finally, Phase 3 trials typically enroll thousands of individuals and provide the critical documentation of effectiveness and important additional safety data required for licensing. At any stage of the clinical or animal studies, if data raise significant concerns about either safety or effectiveness, FDA may request additional information or studies, or may halt ongoing clinical studies.
So any vaccine will have to be shown safe and effective in clinical trials to get approved. They also continue to investigate the safety of the vaccines:
The FDA continues to oversee the production of vaccines after the vaccine and the manufacturing processes are approved, in order to ensure continuing safety.
