This is correct: the current position of the medical establishment is that we simply don't have enough data to make an extremely strong argument for vaccines for healthy people.
To be clear, do you mean no additional benefit for booster vaccines (not the original series)?
I don't know enough about the boosters yet (and nobody does). We'll have a better idea in January after the winter cycle is winding down.
And nobody knows enough about the flu vaccine currently yearly formulation in every year of the last 50+, but it was still recommended and administered to 40+% of US adults. Covid-related antivaxxism is just latent antivaxxers finally coming clean.
Watch the TWiV videos, they go into detail, and I time stamped them
