How to Understand COVID-19 Variants and Their Effects on Vaccines
2dViruses evolve. It's what they do. That's especially true for a pandemic virus like SARS-CoV-2, the one behind COVID-19. When a population lacks immunity and transmission is extensive, we expect viral mutations to appear frequently simply due to the number of viruses replicating in a short period of time. And the growing presence of immune individuals means that the viruses that can still transmi
