"Certainly, if you've had a booster shot, you're less likely to catch Delta," she said. Yes, and research suggests Omicron is more capable of reinfecting people who have already had COVID than past variants. But to persist, viruses like SARS-CoV-2 introduce random mutations in their genome when they replicate, aiming to continuously alter their proteins to escape immune recognition.
