Animal study suggests Omicron is less infectious than ...
The omicron (B.1.1.529) SARS-CoV-2 variant of concern does not readily infect Syrian hamsters
Abstract
The emergence of SARS-CoV-2 variants of concern (VoCs) has exacerbated the COVID-19 pandemic. End of November 2021, a new SARS-CoV-2 variant namely the omicron (B.1.1.529) emerged. Since this omicron variant is heavily mutated in the spike protein, WHO classified this variant as the 5th variant of concern (VoC). We previously demonstrated that the other SARS-CoV-2 VoCs replicate efficiently in Syrian hamsters, alike also the ancestral strains. We here wanted to explore the infectivity of the omicron variant in comparison to the ancestral D614G strain. Strikingly, in hamsters that had been infected with the omicron variant, a 3 log10 lower viral RNA load was detected in the lungs as compared to animals infected with D614G and no infectious virus was detectable in this organ. Moreover, histopathological examination of the lungs from omicron-infecetd hamsters revealed no signs of peri-bronchial inflammation or bronchopneumonia. Further experiments are needed to determine whether the omicron VoC replicates possibly more efficiently in the upper respiratory tract of hamsters than in their lungs.

もし オミクロン感染急拡大の原因がオミクロン株の感染力の高さじゃないとしたらあり得る原因は・・・
ワクチン接種者の免疫力の急低下しかあり得ないわけですが・・・（爆ｗｗｗｗｗｗｗｗｗ

もしもコロナが接種者と未接種者を見分けるように進化している最中とすれば？ 接種未接種の相違はあるはずですね 感染者の比率からは検証できないですが オミクロンが接種者を狙ってるとしたら？次の進化は・・
「感染力は高いからっっっ」って言えば言うほど
感染力も毒性も低い変異株の存在証明に‥
今迄どれだけ無害かそれに近い株がどれだけあるかなど
広報してこなかったのを悔いるんだ ってなるねw
ワクチン推進肯定ありきで
でっち上げに必死だったからこうなる
