I see the data daily from a major MI hospital system. They test lots of their employees and greater than 90% of their positive tests are in staff not fully vaccinated. Also, well over 90% of their COVID 19 hospitalizations are in folks not fully vaccinated. This implies to me that the early evidence for the vaccines is very positive. I do not disagree with those who say the long term results are not certain. We are certainly in uncharted territory with this virus. Seek out reliable sources and decide for yourself.
