CNN, July 9, 2021 [1]:
> Drugmaker Pfizer said Thursday it is seeing waning immunity from its coronavirus vaccine and says it is picking up its efforts to develop a booster dose that will protect people from variants.
Axios, May 19, 2021 [2]:
> “The data that I see coming, they are supporting the notion that likely there will be a need for a booster somewhere between 8 and 12 months.” – Pfizer CEO
Marketwatch, May 25, 2021 [3]
> Moderna and Pfizer are already developing COVID-19 vaccine boosters. Do we need a third shot?
> Vaccine makers say immunity to the virus can begin to wane after six or eight months.
> It looks like Americans may need to roll up their sleeves for a COVID-19 booster shot, though vaccine makers and federal officials are still trying to detect how long immunity to the virus lasts.
> The COVID-19 vaccines developed by these companies, as well as the Johnson & Johnson — the third vaccine to be authorized in the U.S. — are all considered very effective, especially when it comes to preventing hospitalization and death, but it’s still unknown how long they can protect people against the virus.

Seems to underscore my point that the available information about immunity longevity is mixed at best.
No one following the news and research in good faith believes that there was any solemn promise made about never needing boosters or never having immunity wane.
We've had studies that show a wide variety of different results and insights (to be expected), the preponderance of which has supported the idea that these vaccines do NOT have unlimited durability and that boosters would be needed.
