We of course have to observe this over time, because many people got boosted more recently. What we're seeing is that third doses do increase protection against infection or symptomatic disease and, therefore, transmission, but that does decline over time. We're just trying to plot to see how fast that waning occurs. We need a bit more time, but it does decline so you can still potentially get infected.
The vaccine effectiveness against severe disease was boosted to very high levels of over 90%. Even over time that just gradually decreases, so we need more time to figure out the duration of protection. It does seem to be quite good at the moment, but we'll certainly provide further updates as time goes on.
