健康な成人におけるインフルエンザに対する修飾RNAワクチンに関する研究
健康な成人におけるインフルエンザに対する改変RNAワクチンの安全性、忍容性、免疫原性を評価する研究
この研究の目的は、インフルエンザ予防のための修飾 RNA (modRNA) ワクチンが次のようなものであるかどうかを調べることです。
- 安全;そして
- これらのワクチンが一般的に健康な成人にどのように免疫反応を引き起こすのか。 免疫反応は、有害または異物とみなされるものから体を守る方法です。
RNA (リボ核酸とも呼ばれる) は、細胞によって作られる 2 種類の核酸のうちの 1 つです。 RNA には、DNA (他の種類の核酸) からコピーされた情報が含まれています。 細胞はいくつかの異なる形式の RNA を生成し、それぞれの形式が細胞内で特定の役割を果たします。 RNA の多くの形態は、タンパク質の生成に関連する機能を持っています。 RNA は、一部のウイルスの遺伝物質でもあり、DNA の代わりに使用されます。 RNA は研究室で作成でき、研究に使用できます。 リボ核酸とも呼ばれます。
インフルエンザは、インフルエンザの病気を表す用語です。 口、鼻、喉に影響を及ぼすウイルスによる感染症です。
この研究では、次のような参加者を求めています。
- 18歳以上です
- 過去6か月以内にインフルエンザワクチンを受けていない
- 概して健康である
この研究は、サブスタディ A (SSA)、サブスタディ B (SSB)、およびサブスタディ C (SSC) の 3 つのサブスタディに分割されます。
サブ研究に関係なく、すべての参加者は、次のワクチンのいずれかを腕に注射として 1 回投与されます。
- 研究中のmodRNAインフルエンザワクチンの1つ。または
- それぞれの年齢層での使用が承認された承認済みのインフルエンザワクチン。
参加者は約6か月間この研究に参加します。 この期間中、参加者は少なくとも 3 回のクリニックを受診します。

|
Local reactions included pain at the injection site, redness and swelling and were recorded by participants in the electronic dairy (e-diary) or by investigators in case report form (CRF) after vaccination.
All local reactions were graded based on center for biologics evaluation and research (CBER) toxicity guidelines as Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe) and Grade 4 (potentially life-threatening).
In this outcome measure, data is reported as percentage of participants with any local reaction of any grade.
