It's very important. It's a truism, albeit a worn-out truism, that viruses don't respect borders. We really need to have collaboration so that when variants become apparent in any jurisdiction anywhere in the world, they're very quickly shared so they can be sequenced. If revised vaccines need to be made, it needs to be done very quickly.
There's an incredible amount of data sharing and material sharing around the world that we didn't see 10 or 20 years ago with previous pandemics, including the routine influenza pandemics. I think it's incredibly important to have that type of collaboration around the world to make sure that we have very early warnings so that we can develop interventions that are effective.
