ファイザーのワクチン1回でデルタ重症化は94%防げる、と

 

英国の分析だと、デルタ型の重症化率はアルファ型の2倍で、基礎疾患がある人が重症化しやすいと。ただ、ファイザーのワクチン1回で重症化は94%防げるとのこと。発症については、ファイザー2回で79%とのこと。 https://t.co/CuKQWAOq3p

UK study: Pfizer, AstraZeneca vaccines offer protection against Delta variant

BY JUSTINE COLEMAN - 06/14/21 02:33 PM EDT

A British study released on Monday found that the Pfizer-BioNTech and AstraZeneca COVID-19 vaccines offer solid protection against hospitalization due to the Delta variant, which recently became the dominant strain in the country. 

Public Health England determined that the full two-dose Pfizer-BioNTech vaccine offers 96 percent protection against hospitalization, and the AstraZeneca vaccine gives 92 percent protection against hospitalization

Pfizer, AstraZeneca preventing hospitalizations from Delta variant in Britain

Last month, Public Health England said a single dose of Pfizer or AstraZeneca was only about 33 per cent effective at preventing symptomatic cases of COVID-19 after one dose, but after two doses, that rose to 88 per cent for Pfizer and 60 per cent for AstraZeneca.

On Monday, Public Health England said it had new data that showed the vaccines were doing really well at keeping people from getting extremely sick.

The study, based on 14,000 people with confirmed cases of COVID-19 due to the Delta variant between April 12 and June 4, found two doses of either vaccine were more than 90 per cent effective at keeping people out of the hospital. There were a total of 166 hospitalizations in the group.

After one dose, Pfizer was 94 per cent effective against hospitalization, and AstraZeneca's vaccine was 71 per cent effective.

アストラでも２回の接種で重症化９４％防げる、というのは台湾にとっても朗報だね。

こっちから引用していたんだろうね。 

デルタ型の症状は、嗅覚や味覚の喪失といった従来のコロナの症状よりも、頭痛や喉の痛み、鼻水など普通の風邪の症状と近いとのこと。嗅覚の喪失は、報告された症状のトップ10にはもはや入らないとのこと。 https://t.co/ZEl28Rb0ZM

なるほど。
