Omicron does reinfect after natural infection

Reinfections are probable, not good news actually How likely somebody who has already had Covid to catch Omicron? (catching it twice or more) Increased risk of SARS-CoV-2 reinfection associated with emergence of the Omicron variant in South Africa What is already known on this topic Prior infection with SARS-CoV-2 is estimated to provide 84% reduction in infection risk What this study adds We find no evidence of increased reinfection risk associated with circulation of Beta or Delta variants, compared to the ancestral strain in routine epidemiological data from South Africa. In contrast, we find clear, population-level evidence to suggest substantial immune evasion by the Omicron variant. Omicron selection advantage is at least partially driven by an increased ability to infect previously infected individuals. Omicron variant increases reinfection risk - Yes Omicron variant of SARS-CoV-2 demonstrates substantial popula
