Examine suggests Omicron much less extreme even for unvaccinated

Omicron globally has tended to trigger much less extreme illness, and proportionally fewer hospital admissions and deaths, than earlier variants.

Scientists are attempting to find out the extent to which that is due to larger immunity charges engendered by vaccination or previous sickness, or Omicron is intrinsically much less nasty.

The examine concluded that a couple of quarter of the diminished threat of extreme illness with Omicron was attributable to traits of the virus itself.

“Within the Omicron-driven wave, extreme Covid-19 outcomes had been diminished largely as a result of safety conferred by prior an infection and/or vaccination, however intrinsically diminished virulence could account for an roughly 25% diminished threat of extreme hospitalisation or demise in comparison with Delta,” the examine mentioned.
