Omicron is inherently less virulent than coven 19. This may explain why people who are vax nated and have a booster shot are getting break through cases of coven 19 that end up being pretty mild. It's still possible that a new variant could emerge down the road that we'll evade, or that we'll be able to get around that wall of immunity that we've built up. But these early studies seem to suggest that there will be cross protective immunity for people infected with omacron against future aberians.
