Peer-reviewed research from The Lancet shows that the experimental vaccines reduce your chances of catching COVID-19 by:
Pfizer: 0.8%
J & J: 1.2%
Moderna: 1.2%
AstraZeneca: 1.3%
“…The absolute risk reduction (ARR), which is the difference between attack rates with and without a vaccine, considers the whole population. ARRs tend to be ignored because they give a much less impressive effect size than RRRS: 1.3% for the AstraZeneca-Oxford, 1.2% for the Moderna-NIH, 1.2% for the J&J, 0.93% for the Gamaleya, and 0.84% for the Pfizer-BioNTech vaxxine.”

In other words – NO prevention… NONE!
