The risk of severe outcomes following SARS-CoV-2 infection is substantially lower for Omicron than for Delta. After adjusting for the impact of prior infection and vaccination the study found that the hospitalisation rate was 59% lower for Omicron compared to Delta and the risk of dying was 69% lower. Vaccination was somewhat less effective against Omicron than against Delta. However, its effect against Omicron was still substantial, reducing the risk of hospitalisation and death by 70% after three jabs of an mRNA vaccine. Hong Kong’s vaccination rates are low, particularly among those 70 and over.
