Eine Studie über modifizierte RNA-Impfstoffe gegen Influenza bei gesunden Erwachsenen
Eine Studie zur Bewertung der Sicherheit, Verträglichkeit und Immunogenität von modifizierten RNA-Impfstoffen gegen Grippe bei gesunden Erwachsenen
Der Zweck dieser Studie besteht darin herauszufinden, ob modifizierte RNA-Impfstoffe (modRNA) zur Vorbeugung von Influenza:
- sicher; Und
- wie diese Impfstoffe bei im Allgemeinen gesunden Erwachsenen eine Immunantwort hervorrufen. Die Immunantwort ist die Art und Weise, wie sich der Körper vor Dingen schützt, die er als schädlich oder fremd ansieht.
RNA (auch Ribonukleinsäure genannt) ist eine von zwei Arten von Nukleinsäuren, die von Zellen hergestellt werden. RNA enthält Informationen, die von DNA (der anderen Art von Nukleinsäure) kopiert wurden. Zellen produzieren verschiedene Formen von RNA, und jede Form hat eine bestimmte Aufgabe in der Zelle. Viele Formen der RNA haben Funktionen im Zusammenhang mit der Herstellung von Proteinen. RNA ist anstelle von DNA auch das genetische Material einiger Viren. RNA kann im Labor hergestellt und in Forschungsstudien verwendet werden. Auch Ribonukleinsäure genannt.
Influenza ist die Bezeichnung für eine Grippeerkrankung. Es handelt sich um eine durch ein Virus verursachte Infektion, die Mund, Nase und Rachen befällt.
Die Studie sucht Teilnehmer, die:
- sind mindestens 18 Jahre alt
- in den letzten 6 Monaten keinen Grippeimpfstoff erhalten haben
- sind grundsätzlich gesund
Diese Studie wird in drei Teilstudien unterteilt: Teilstudie A (SSA), Teilstudie B (SSB) und Teilstudie C (SSC).
Alle Teilnehmer, unabhängig von der Teilstudie, erhalten 1 Dosis eines der folgenden Impfstoffe als Injektion in ihren Arm:
- 1 der untersuchten modRNA-Influenza-Impfstoffe; oder
- einen zugelassenen Grippeimpfstoff, der für die Verwendung in ihrer jeweiligen Altersgruppe zugelassen ist.
Die Teilnehmer werden etwa 6 Monate lang an dieser Studie beteiligt sein. Während dieser Zeit haben die Teilnehmer mindestens drei Klinikbesuche.
