Scientists are racing to establish the variant’s transmissibility, effect on immune system and chance of hospitalisation or death
Three major issues will determine the magnitude of the impact of the new Omicron variant of the Covid virus will have on the nation and the rest of the planet. What is the transmissibility of this new Covid variant? How good is it at evading the antibodies and T-cells that make up a person’s immune defences?
