No medical treatment is perfect. Vaccines do not prevent disease - they REDUCE THE RISK of infection, hospitalization, death and transmission of the disease.
Also as the virus evolves, things change. It's hard to predict mother nature. From an infection perspective, Delta was more like a different virus.
These points could have been communicated/comprehended better by the medical and scientific community throughout the disease.
Nobody knows about Omicron. Perhaps it will be a more infectious disease with mild severity similar to a cold that will out compete more severe virus like Delta. We can only hope.
