重症化率 これから支配的になるデルタ型はいまのアルファ型の2倍 接種遅れて失う命

英国のデータではワクチン未接種者の重症化率がアルファ型の2倍と言われている新しい変異型デルタによる重症者の増加予測を、デルタ型の感染が起きていない日本の過去のデータから検証できるという根拠は何でしょうか？ https://t.co/ze2UH9PKCg

Delta variant impact on hospitalisation revealed

The Delta variant of Covid-19 is associated with approximately double the risk of hospitalisation compared with the Alpha variant, according to a new nationwide study.

Vaccinations 

Vaccines were found to reduce the risk of being admitted to hospital, but strong protective effects against the Delta variant were not seen until at least 28 days after the first vaccine dose.

In community cases at least two weeks after the second dose, the Pfizer-BioNTech vaccine was found to provide 79 per cent protection against infection from the Delta variant, compared with 92 per cent against the Alpha variant.

For the same scenario, the Oxford-AstraZeneca vaccine offered  60 per cent protection against infection with the Delta variant compared with 73 per cent for the Alpha variant. This lower vaccine effect may reflect that is takes longer to develop immunity with Oxford-AstraZeneca, experts say.

一回目の接種から28日後は効果がでてくるわけかあ。

で、デルタ型に対してはファイザー79％　アストラ60％の予防率　つまりアストラでも効果はでている。 

Press release

Vaccines highly effective against hospitalisation from Delta variant

the Pfizer-BioNTech vaccine is 96% effective against hospitalisation after 2 doses

the Oxford-AstraZeneca vaccine is 92% effective against hospitalisation after 2 doses

重症化率というのか入院化率というのか、ファイザーは９６％有効　アストラでも９２％有効・・・・

・・ワクチン接種が遅れて失う命もあるんだろうな、これから。

無能な大臣をもつと日本も不幸だなああ。
