“Omicron spreads faster than Delta among those who are fully vaccinated”
Not that it spreads faster among the vaccinated, than among unvaccinated.
Just that Omicron evades all prior immunity - whether from vaccination or prior infection - more than Delta.
There is still some protective vaccine effect against Omicron, especially against severe disease or death.
I guess being three paragraphs in... it was a little past your attention span. ““Comparing households infected with the Omicron to Delta VOC, we found an 1.17 times higher SAR for unvaccinated, 2.61 times higher for fully vaccinated and 3.66 times higher for booster-vaccinated individuals”.
I know it's hard, let's make it a little simpler for you; the bigger numbers are bad. So, to repeat they go from 1.17 for unvaccinated, to 2.61 for vaccinated to 3.66 for booster vaccinated. “SAR refers to secondary attack rate.” But don't worry even though this is too difficult for you to understand, we still love you.
