@cjones47 @DKThomp That graph has not aligned with efficacy studies since at least Omicron. Probably has do to with unvaxed infections being more severe and more likely to be picked up by limited testing, but there could be other demographic factors.
@cjones47@DKThomp该图至少自Omicron以来就与疗效研究不一致。这可能与未接种疫苗的感染更加严重以及通过有限的检测更容易感染有关，但也可能有其他人口因素。
