They do not.
Treating the vaccines like a panacea in order to get more people vaccinated has been a huge mistake.
These "experts" have totally oversold the vaccines, promising the moon.
Countless people have become infected as a result, and many have died.
Michigan achieved 50% fully vaccinated on August 24th, the level at which Anthony Fauci at least three times indicated would be sufficient to guarantee that there would not be another surge.
The experts couldn't have been more wrong.
“I certainly have seen people misinterpret this as vaccines (are not) effective,” said Dr. Sarah Lyon-Callo, the state’s top epidemiologist with the Michigan Department of Health and Human Services. In fact, the opposite is true, she said. “The vaccines still make a big difference in terms of community spread and the risk of severe outcomes for individuals.”

CDC has said differently since the July 4 Provincetown outbreak, and is repeating it again now:
This investigation highlights that the Delta variant of SARS-CoV-2 can spread quickly through a highly vaccinated population and can be transmitted to others regardless of vaccination status. ... our findings underscore the need for persons who are fully vaccinated to take precautions to prevent transmission of SARS-CoV-2 to themselves and others, such as wearing a mask in public indoor settings or crowded outdoor settings, particularly during substantial or high transmission. Vaccination, although critical to reduce illness and death from COVID-19, should be complemented by layered mitigation strategies to address the COVID-19 pandemic (25,31).
