Not only is the CureVac vaccine late to the game, but preliminary data shows it is only 47 percent effective in preventing COVID-19.

mRNAワクチンだからといって「ぱねぇ」とは限らず独CureVac社製ワクチンの2回接種後の有効率は47%。原因はModernaとBioNtech/Pfizerはプソイドウリジンを組み込んだ修飾RNAを使用してるのに対しCureVacはウリジンを使用したためだろうとのこと。　https://t.co/S8dpZtY7UD https://t.co/YhV923qlcp

CureVac COVID vaccine let-down spotlights mRNA design challenges

(I agree, the problem is the dose was too low, far lower than Pfizer or Moderna)https://t.co/EUHgucA32B

Costly Mistake
In the vaccine battle between pseudouridine modified & unmodified RNA, round one goes to modified RNA
Failure of CureVacs mRNA vaccine using unmodified RNA (dose limited by toxicity is a major setback for the company. #CovidVaccine https://t.co/abu3knUfc5

第３のmRNAワクチン、期待はずれ。ドイツのCureVacは、6月16日に40,000人の試験からの予備データが残念な結果に終わったと発表した。先行の２つのmRNAワクチンとは違い冷蔵保存が可能などの利点があったが、その修飾されていない塩基のせいで、投与量を上げられなかったからかhttps://t.co/OgFkGsO6ZO

CureVac blamed the poor performance of its mRNA vaccine on virus variants. But the vaccine itself may be the problem, @sciencecohen reports. https://t.co/ODY4ERSboH

Lots of theories about why CureVac's mRNA vaccine performed so poorly. Could it be that it was too natural?https://t.co/zdyudasMiK pic.twitter.com/aqmB8CjcBc
