As a layman, I could guess that people get infected so much they can't be vaccinated anymore.
However, I believe that people think the vaccine is more harmful than admitted, caused by the public wasteland inhabited by mentally impaired antivaxers and officials carefully omitting topics, leaving lots of room for propaganda and gut feeling.
If you are still interested in prevention of respiratory disease, you might want to read this one:

By the number of identical sequences alone, this better be a total outlier.
The SARS-2 vaccine efficacy looks a bit poor against severe disease now.
Does anyone know whether they tried to correct for widespread infection?
