Hier gibt es eine aktuelle Studie zu Omikron aus Dänemark.

»Since the identification of the first Omicron case in Denmark, a steep increase in the number of cases has been observed. A major driver of this development was a large party with young adults – a population group with more social and close connections than adults and children. […]

The response strategy in Denmark has been to delay transmission of the Omicron variant in order to gain time for roll-out of the third vaccine dose and the recently initiated vaccination programme for children aged 5 to 11 years. […]

It is of concern that 83% of cases occurred in fully or booster-vaccinated people. Whether this observation is an artefact as the major superspreading events and subsequent chains of transmission have occurred primarily in young adults, and not yet spread to children, who have not been vaccinated, is still too early to say. The data are too immature to allow analysing the cases by vaccine type.

However, it can be mentioned that 76% of the Danish population are fully vaccinated and 84% of these have received Comirnaty (Pfizer/BioNTech, Mainz, Germany/ New York, United States) followed by 14% with Spikevax (Moderna, Cambridge, United States). […]

Of note, the earliest Omicron cases in Denmark occurred before South Africa announced the emergence of this variant. These cases reported travel history from Qatar and the Netherlands, indicating that the variant might have spread from the African continent before this. Also, later Danish travel-related cases are not only found among travellers returning from South Africa but also from other European countries, indicating that community spread is likely to be more widespread than reported.

Denmark has one of the highest RT-PCR testing capacities in the world and screens all positive RT-PCR tests with an Omicron-specific PCR [11]. Linking this information with national registers allows us to give a detailed overview of the early spread of the Omicron variant.

We find several reasons for concern:
(i) the rapid spread shortly after introduction despite extensive contact tracing efforts,
(ii) the occurrence of several superspreading events with high attack rates and
(iii) the high proportion of fully vaccinated Omicron cases.

We observed nine hospitalisations and one case needed intensive care treatment. Owing to limited follow-up time and few admissions, it is too early to conclude on the severity of the Omicron variant.«

Meiner Meinung nach ist das ein gutes Beispiel, wie Wissenschaft in einer Pandemie arbeiten sollte.
