" An Imperial College outbreak modelling team led by Prof Neil Ferguson analysed hospitalisations and vaccine records among all PCR-confirmed Covid cases in England between 1 and 14 December. The dataset included 56,000 cases of Omicron and 269,000 cases of Delta.
Their report found that the risk of any attendance at hospital was 20% to 25% lower with Omicron versus Delta, and 40%-45% lower when the visit resulted in admission for at least one night. For the small percentage of people who had neither been previously infected with Covid nor vaccinated, the risk of hospitalisation was about 11% lower for Omicron versus Delta.
Ferguson said that while it was "good news", the assessment did not substantially change Sage modelling pointing to 3,000 daily hospitalisations in England at the peak of the wave next month without restrictions beyond the plan B measures currently in place.
While the analysis shows evidence of "a moderate reduction" in the risk of hospitalisation associated with Omicron compared with Delta, Ferguson said, "this appears to be offset by the reduced efficacy of vaccines against infection with the Omicron variant"."
Direi che avrebbe senso riportare i dati come sono e man mano che arrivano, piuttosto che artatamemte manipolare le persone per poi fare marcia indietro (o più spesso far finta di niente) quando è troppo tardi
