There was a lot more said about it in April which was even more negative.
But even on July 8, with Delta raging throughout the US, and with many (mostly elderly) Americans approaching 6 months from their second shot, this statement was released by the CDC/FDA:
Joint CDC and FDA Statement on Vaccine Boosters
The United States is fortunate to have highly effective vaccines that are widely available for those aged 12 and up. People who are fully vaccinated are protected from severe disease and death, including from the variants currently circulating in the country such as Delta. People who are not vaccinated remain at risk. Virtually all COVID-19 hospitalizations and deaths are among those who are unvaccinated. We encourage Americans who have not yet been vaccinated to get vaccinated as soon as possible to protect themselves and their community.
Americans who have been fully vaccinated do not need a booster shot at this time. FDA, CDC, and NIH are engaged in a science-based, rigorous process to consider whether or when a booster might be necessary. This process takes into account laboratory data, clinical trial data, and cohort data – which can include data from specific pharmaceutical companies, but does not rely on those data exclusively. We continue to review any new data as it becomes available and will keep the public informed. We are prepared for booster doses if and when the science demonstrates that they are needed.

This was despite the fact that Pfizer determined as early as February that a booster was going to be necessary, and Israel started giving the booster in the same month as the FDA/CDC was denying Americans needed one.
Note the language above. They didn't say that the need for the booster was possible but not yet proven. They clearly said that fully vaxxed Americans DO NOT need a booster, which was a flat out lie. The final sentence said they were "prepared for booster doses if and when" that conclusion changed.
So we can believe one of two things here:
1) Pfizer, Moderna, and Israel all knew we needed boosters, but somehow top US scientists didn't.
-or-
2) They were lying to us because they wanted to encourage more first-time vaccination.
I'll let you guess which one is more likely.
