Een onderzoek naar gemodificeerde RNA-vaccins tegen griep bij gezonde volwassenen
EEN ONDERZOEK OM DE VEILIGHEID, VERDRAAGBAARHEID EN IMMUNOGENICITEIT VAN GEMODIFICEERDE RNA-VACCINS TEGEN INFLUENZA BIJ GEZONDE VOLWASSENEN TE EVALUEREN
Het doel van deze studie is om erachter te komen of gemodificeerde RNA (modRNA)-vaccins voor de preventie van griep:
- veilig; En
- hoe deze vaccins een immuunrespons veroorzaken bij over het algemeen gezonde volwassenen. Immuunreactie is de manier waarop het lichaam zichzelf beschermt tegen dingen die het als schadelijk of vreemd beschouwt.
RNA (ook wel ribonucleïnezuur genoemd) is een van de twee soorten nucleïnezuur die door cellen worden gemaakt. RNA bevat informatie die is gekopieerd van DNA (het andere type nucleïnezuur). Cellen maken verschillende vormen van RNA, en elke vorm heeft een specifieke taak in de cel. Veel vormen van RNA hebben functies die verband houden met het maken van eiwitten. RNA is ook het genetische materiaal van sommige virussen in plaats van DNA. RNA kan in het laboratorium worden gemaakt en in onderzoeksstudies worden gebruikt. Ook wel ribonucleïnezuur genoemd.
Influenza is een term die wordt gebruikt voor griepziekte. Het is een infectie veroorzaakt door een virus dat uw mond, neus en keel aantast.
Het onderzoek is op zoek naar deelnemers die:
- minimaal 18 jaar oud zijn
- u de afgelopen 6 maanden geen griepvaccin heeft gekregen
- zijn over het algemeen gezond
Dit onderzoek wordt opgedeeld in drie deelonderzoeken: Deelonderzoek A (SSA), Deelonderzoek B (SSB) en Deelonderzoek C (SSC).
Alle deelnemers, ongeacht het deelonderzoek, krijgen 1 dosis van een van de volgende vaccins als injectie in hun arm:
- 1 van de modRNA-griepvaccins die worden onderzocht; of
- een goedgekeurd griepvaccin dat is goedgekeurd voor gebruik in hun respectieve leeftijdsgroep.
Deelnemers zullen ongeveer 6 maanden betrokken zijn bij dit onderzoek. Gedurende deze tijd zullen de deelnemers minimaal 3 kliniekbezoeken afleggen.
