抗体前面有个定语 “omicron subvariant-specific”, 我觉得不是总的抗体数。
官网
这个说的是8-fold, 我没有看明白, 看看大家怎么解读:
“mRNA-1273.214 met all primary endpoints in the Phase 2/3 trial including neutralizing antibody response against Omicron when compared to a 50 µg booster dose of mRNA-1273 in baseline seronegative participants. Pre-specified criteria for superiority as measured by neutralizing geometric mean titer ratio (GMR) with the lower bound of the confidence interval >1 was met. The GMR and corresponding 97.5% confidence interval was 1.75 (1.49, 2.04). A booster dose of mRNA-1273.214 increased neutralizing geometric mean titers (GMT) against Omicron approximately 8-fold above baseline levels. Primary endpoints of non-inferiority against ancestral SARS-CoV-2 were also met, with GMR against ancestral SAR-COV-2 (D614G) of 1.22 (1.08-1.37).
Among seronegative participants one month after administration, the neutralizing GMT against ancestral SARS-CoV-2 for mRNA-1273.214 was 5977 (CI: 5322, 6713) , compared to GMT for mRNA-1273 of 5649 (CI: 5057, 6311). The GMT against Omicron for mRNA-1273.214 was 2372 (CI: 2071, 2718), compared to GMT for mRNA-1273 of 1473 (CI: 1271, 1708).

文中说:"The bivalent booster caused a more than five-fold jump in the levels of omicron subvariant-specific neutralizing antibodies—which can target the virus and prevent it from replicating—a month after receiving the 50 microgram dose, regardless of prior infection, Moderna said."
看到了吧?这个是莫德纳亲口说的,你看它现在还敢说吗?你在官方媒体上,现在还能不能找到这个字眼儿?
结束语:我说了这么多,你也了解到 1)bivalent疫苗抗体数目翻5倍
