The Norwegian institute of public health has made a report on the first Omicron-outbreak 3 weeks ago, when a person arrived from south-africa, went to a christmas party, and ended up infecting more than 100 people at a restaurant.
They have done the research of one of the groups that was in a chambre separee celebrating a company christmas party.
The group was 117 people.
111 Has responded to the questioning in the report. 65 (+15 not yet ready analyzed, so likely 80) was infected with Omicron. (1 had Delta from before).
It's a small group, but probably the best report yet, since they were all infected in the same room at the same time.
I'll link to a NRK write-up on the report below, but here are some highlights:
-Obviously extremely transmissable
-100/111 people had 2 doses of either Pfizer or Moderna. The remaining 11 either vaccinated with something else, only one dose or non-vaccinated. 6/11 in this group were infected, but clearly not a number that is large enough to represent any useful information.
-Some was probably vaccinated with a combination of the two, but their health card only shows the last dose and not the combination.
-Everyone (99%) had symptoms of some kind. No asympthomatic cases (1?) 50% experienced fever.
-No one became seriously ill or required hospitalization. (They were young to middle-aged and vaccinated, so to be expected)
-Almst twice as many of those infected had Pfizer compared to Moderna.
-Almost twice as many of those non-infected had Moderna compared to Pfizer.
Again this is google translated, so not 100% accurate:
First on the symptoms list is Coughing. https://www-nrk-no.translate.goog/norge ... x_tr_hl=no
