I think we're still learning, because you actually have to monitor over time, so you have to get the booster and then we're monitoring over time.
I think what we will see is that the third booster might increase the durability of the protection, but, of course, the virus itself also changes.
What I think we will see, similar to what happened after the second dose, is that the protection against infection will likely be reduced over time but the protection against severe outcomes is likely to be more enduring.
