fights covid. >> sure. let me preface by saying that bacteria and viruses are different. viruses need to replicate within a human cell whereas bacteria don't which is why antibiotics are easier to develop for bacteria than antivirals. we don't hear much about antivirals. as the virus is replicating, it's using different building blocks to make new viruses. what this drug does essentially acts like one of those building blocks like a trojan horse or wolf in sheep's clothing, jake. and then the virus starts to build with this abnormal building block and it messes up the replication process. so the virus can't replicate that much anymore. that's basically what it does. two things to keep in mind. you'd understand why you need to give this drug early. you want to stop replication early. if it replicates a lot, then the virus is already out there quite a bit in the body. this virus, this covid virus is tricky. it has a proofreading mechanism
