We've been for more than a year now, locked in our houses, or being unable to do lots of thing we'd wish of. All because of COVID-19, and we need to do something about it. Researchers have found a cure to this lethal virus, and we need to take this opportunity in order to subsist. We can't live like this forever! That's where the expression "I've got the world's back" comes from, since it has the literal meaning(they are carrying us), and that they are the ones that will help us overcome this virus and be able to go back to normal life.
