We know that once you're boosted, you get into the high nineties in terms of protection against severe disease. We know that, for the most part, it seems to last a number of months, but we don't have data for months and months and months.
With regard to three months out, for the most part the studies are still showing good protection, mostly 70% or higher, and many still in the eighties and nineties, but we need to go out longer to see what the protection for the longer term will be.
