 （ＣＮＮ） 米モデルナが開発した新型コロナウイルスのワクチンについて、同社幹部は１１日、少なくとも１年間は効果が持続するとの見方を示した。

 モデルナのタル・ザックス最高医療責任者（ＣＭＯ）が、ヘルスケア業界の企業や投資家が集まる米ＪＰモルガン主催の年次会議で語った。

 モデルナ製と米ファイザー製のワクチンは米食品医薬品局（ＦＤＡ）の緊急使用許可（ＥＵＡ）を受けているが、いずれも昨年開発されたばかりで、予防効果がどのくらい続くのかは確認されていない。

 モデルナのワクチンは約１カ月の間を置いて２回接種される。ザックス氏は、３回目の接種を追加することで効果をどの程度引き延ばすことができるか、今後さらに研究を重ねると述べた。

(CNN) Regarding the new coronavirus vaccine developed by US Moderna, this company's executive said on the 11th that its effect could last for at least one year.

Moderna’s Chief Marketing Officer Tal Zaks said at an annual meeting hosted by JP Morgan which was a gathering for companies and investors from the healthcare industry.

The Moderna and Pfizer vaccines had been granted an Emergency Use Authorization (EUA) by the US Food and Drug Administration (FDA), but as both were just developed last year, how long their preventive effects could last was not confirmed at that moment.

Moderna's vaccination had to be given twice, about one month apart. Zaks said he would continue to study how the effect of their vaccine could be extended by an additional third dose.

              So, it seems that Moderna could become the most popular vaccine for Covid-19. It is good news to know that this vaccine is effective for over a year. This is longer than I have expected.
