I do not know how often this specific claim is made.
However, a related sentiment I think that is common is that vaccines that are approved are expected to be more efficacious then the jabs turned out to be.
As a matter of fact, many pro-jab proponents stated plainly that if one got these jabs (they used the word vaccine) that one would not get covid. I have seen video of Fauci and of Biden and other jab promoters making this claim.
To be fair to them, I would not hold them to mean that the jab was explicitly 100% effective, but I think it fair to say that they were asserting it is close enough to 100% that one did not have to worry about getting covid after they got the jab.
Then reality happened and the efficacy narrative became a farce. The goal posts were supposedly set by clinical trials before the release to the public, and they kept sliding and sliding. They slid to 60 something percent I think you mentioned a bit ago. Not really confident that the slide will not continue though...just impossible to trust people who were so wrong.

Very frequently. In effect, anytime anyone makes the claim that the vaccines do not prevent covid, they are making this claim.

That claim might have been truthful at the time it was made.
Often overlooked is the virus has mutated. Efficiency against the original variant could well have been close to 100% and approaching 60% against the latest variants. Those are not mutally exclusive.
