I have no idea why you believe a third dose is just marketing. It is plainly obvious that immunity decreases over time, as is the case for all vaccines against flus and similar.

A booster is the normal way to handle it. If there were a way to avoid it, at least one of the many companies working on this would have created it. And one for the regular flu, too, while they are at it, which has not happened in decades.

I didn't say it was just marketing - I was asking for additional data to shed light on how robust (or frail) this result is. I don't think there is enough in this press release.

edit: (maybe you meant to comment on that other comment on this...)

That reminds me, I need to get my Polio booster
