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.

> Seems to underscore my point that the available information about immunity longevity is mixed at best The currently available information shows mixed evidence. But the vaccine campaign began in December/January 2021. Back then, BioNTech's CEO believed the protective effect would last "for at least a year"[1] (Booster shots gained traction in April/May [2], though they were mainly presented as a way to protect against new variants, not waning immunity in general). Waning immunity was never really a topic (until now). You can also see its complete disregard in the "EU Digital COVID Certificate" [3]. Recovered persons are exempt from restrictions for 180 days, fully vaccinated persons indefinitely.

  > But the vaccine campaign began in December/January 2021. Back then, BioNTech's CEO believed the protective effect would last "for at least a year" Being "optimistic that the immunisation effect can last for at least a year," (CEO's words) is a lot different than claiming that the vaccine is a "cure" which will last forever, as the person I was originally responding to was claiming we were told. Claiming that we should be "optimistic that the immunisation effect can last for at least a year," does not mean or imply that we should never have expected or ever require booster shots. Claiming that we should be "optimistic that the immunisation effect can last for at least a year," does not speak to the durability of that immunization over the course of that first year. People are not being advised to get boosters because their immunity is completely gone after 6 months. Many around the world will probably be waiting "at least a year" for their boosters and will have some useful level of immunity all the way up to that booster. Exactly how much is still TBD. > Waning immunity was never really a topic While the mainstream media may not have focused on it, "waning immunity" was a consideration from the get-go for anyone with a basic understanding of virology, vaccines or anyone who chose to be informed.
