The Covid-19 variant Omicron is inherently less severe with reduced hospitalisations even if a patient is unvaccinated, a study has found. People are 36 percent less likely to end up in hospital if they contract the Omicron variant compared to those with Delta.
The reduced risk was observed among both unvaccinated and vaccinated, although those who did have the vaccine had a far lower risk of severe symptoms. Researchers show this suggests Omicron is inherently less severe than previous strains of Covid-19.
In a study published in The Lancet Infectious Diseases, researchers studied all PCR confirmed cases in Denmark with samples taken from the date of the first Omicron-positive sample and the following month.
