 That's me. Hello. OK, so hi. So now we we've got vaccines. We've got the big three that are out there. Moderna, AstraZeneca, Pfizer. So, yeah, take it from there. So the take it from there is that there are eight billion people in the world and we want all of them, as many of them as possible, at least 70 percent of them, some say, to get a vaccine, which means we want multiple COVID vaccines. We're going to need more than three.
