Very happy that this work is finally out in a peer reviewed journal: @NatureComms
“Household transmission of the SARS-CoV-2 Omicron variant in Denmark”
Read it here: nature.com/articles/s4146…

A short thread with the new/updated results.
1/ We investigate the secondary attack rate (SAR) in households infected with #SARSCoV2 #Omicron vs #Delta in Demark, 9-22 December 2021.

“Transmission of SARS-CoV-2 Omicron VOC subvariants BA.1 and BA.2: Evidence from Danish Households”
We investigate the secondary attack rate (SAR) in #Omicron BA.1 vs. BA.2 households in Demark, 20 December 2021 – 18 January 2022.

1/ ImageImage We conclude that Omicron BA.2 is inherently substantially more transmissible than BA.1. It also possesses immune-evasive properties that reduce the protective effect of vac. against infection, but do not increase its transmissibility from vac. persons with breakthrough infect.

Effect of Vaccination on Household Transmission of SARS-CoV-2 Delta VOC
We investigate the secondary attack rate (SAR) in #Delta households in Demark, June-November December 2021.
medrxiv.org/cgi/content/sh…
1/N We have 24,693 primary cases (33% fully vaccinated) and 53,584 potential secondary cases (49% fully vaccinated).
The SAR was generally lower among vaccinated potential secondary cases than among unvaccinated.

SARS-CoV-2 Omicron VOC Transmission in Danish Households
We investigate the secondary attack rate (SAR) in #Omicron vs #Delta households in Demark, 9th-19th December 2021.

1/N Image Overall, our findings confirm that the rapid spread of Omicron can primarily be ascribed to the immune evasiveness rather than an inherent increase in the basic transmissibility.
