> 8% sounds a rounding error and probably within the error margins.
It is not.
Erm yes it is ... from the study:
> In adjusted analyses, we estimated that any vaccination ... reduced an index case’s risk of transmitting infection by 22% (6–36%)
CI is much wider than 8pp and the estimated absolute transmission risk CIs actually overlap at 31%. So the study results are consistent with there being no actual difference, also.
If this is the best evidence of a difference in transmission it's not very good.
Also this is Omicron which hardly matters. The justification was the earlier variants.
It is not. The study is available for you to review if you like.
> And now we have the opposite situation with those who have had the most boosters and now more likely to catch the new variant that is out.
I’d like to see that study. Cite, please.
