A Danish study of nearly 12,000 households has discovered that Omicron spreads faster than Delta among those who are fully vaccinated, and even higher between those who have received booster shots, demonstrating strong evidence of the variant’s immune evasiveness.
“Comparing households infected with the Omicron to Delta VOC, we found an 1.17 times higher SAR for unvaccinated, 2.61 times higher for fully vaccinated and 3.66 times higher for booster-vaccinated individuals, demonstrating strong evidence of immune evasiveness of the Omicron VOC,” said the preprint of the study. SAR refers to secondary attack rate.
