  • In this study, the authors use household data from Denmark to investigate the transmissibility of the BA.1 and BA.2 Omicron SARS-CoV-2 subvariants. They find that the secondary attack rate was higher for BA.2, but that it had higher infectiousness only when cases were not vaccinated.

  • Establishing the relative transmissibility of emerging variants of SARS-CoV-2 is key for pandemic management. Here, the authors use full-population administrative data from Denmark linked to PCR test results and estimate that the Alpha variant was ~60% higher than other strains circulating in early 2021.

  • COVID-19 vaccines may reduce the susceptibility of an individual to infection and/or the infectiousness of breakthrough infections. Here, the authors use data from Denmark and estimate that vaccine effectiveness was 61% for susceptibility and 31% for infectiousness during a period of Delta variant dominance.

  • In this study, the authors compare the transmission dynamics of the Delta and Omicron SARS-CoV-2 variants using household data from Denmark. They find that Omicron has a higher secondary attack rate, and that the odds of infection with Omicron was higher than with Delta, particularly for vaccinated individuals.
