I wrote; "we currently think immunity wanes STARTING at 6-12 months". The waning could go for a longer period of time, and that will be individual (as it is for other immunizations). People who were in the trials are still being followed, and recently Pfizer stated they believe immunity may *start* to wane at around 8 months. They are doing quantitative titer testing.
Got it. I am a bit tired and didn't read it closely enough.
The good news is the memory b cells may provide some protection well beyond the waning of the regular antibody response.
