This is a short answer question that I'm unable to figure out correctly. If you could answer it thoroughly, it would be much appreciated! Thank you

The aggregate demand / aggregate supply model is quite useful tool for us to understand the economy. So far, we saw only one change at a time, however, in reality, there can be multiple shocks at the same time. The economy was in long run equilibrium. Assuming all else equal, world scientists collaborated to invent a super vaccine for everyone to be safe from deadly viruses, raising productivity. This makes consumers and businesses optimistic about the economy. At the same time, the oil market is calm, maintaining a stable supply. Given above scenario, what do you think will happen to the LRAS, SRAS and AD curves in each in the short run? And what would happen to price level and output in the economy? What about the long run?
