重症、入院、死亡にはかなり有効

USのワクチンのブースターショット，いったん獲得後に時を経て消えた抗体を復活せせるイメージだが，2回の接種では十分な抗体反応がない免疫不全者をまずは想定してるようだね。3回接種後に抗体を得た人のデータが多く集まっている模様。漏れを塞ぐためのブースター。https://t.co/RZ88gg9Wry

GOUNDER: The data are clear that vaccines remain highly protective against severe disease, hospitalization and death, even with time and against the Delta variant. We’re not seeing waning protection against hospitalization and death. What we are seeing is reduced immunity against the Delta variant with respect to infection.

CROTTY:
There was a paper in Science last week on the Moderna vaccine showing antibodies at six months from the second vaccination, and there wasn’t that much of a decline

It will probably last pretty well for one year plus.

. Are boosters needed? Not for hospitalizations or deaths.

Are boosters going to work? Yeah, the Moderna clinical trial data show that, as well as data from Pfizer. They’re going to top up antibody titers. But do we need them? Uncertain.

ま、結果がわかるまで急がなくていいな、日本は。
