Säkerhetsstudie av ett vaccin för att skydda mot borrelia hos friska barn
EN FAS 3, RANDOMISERAD, PLACEBO-KONTROLLERAD, OBSERVATÖR-BLINDAD FÖRSÖK FÖR ATT UTVÄRDERA SÄKERHETEN FÖR ETT 6-VALENT OSPA-BASERAT LYME SJUKVACCIN (VLA15) PÅ FRISKA BARN 5 TILL 17 ÅR
Denna studie är för att förstå om studievaccinet (kallat VLA15) är säkert hos friska barn.
Vi söker barn som:
- är friska
- är mellan 5 och 17 år
- har inte diagnostiserats med någon form av borrelia tidigare
- har inte fått några vacciner mot borrelia tidigare
Borrelia förekommer oftast hos barn i denna ålder. Studievaccinet kan eventuellt användas för att förhindra borrelia. Målet med denna studie är att få mer information om studievaccinets säkerhet i denna åldersgrupp.
Deltagarna kommer att vara med i denna studie i cirka 2 år. Under den tiden kommer de att få VLA15 eller placebo (steril saltvattenlösning) genom ett "skott" i armen. Vi kommer att jämföra erfarenheten av barn som får VLA15 med de som får placebo. Deltagarna kommer inte att veta om de får VLA15 eller placebo.
Alla som deltar i denna studie kommer att:
- få skotten på en klinik eller på ett sjukhuskontor
- få totalt 4 skott
- få de första 3 skotten inom 6 månader
- få det sista skottet ca 1 år efteråt
- måste komma till prövningsplatsen för 6 planerade besök; 4 av dessa är vaccinationsbesök och 2 är uppföljningsbesök. Vi kommer att kontakta dig per telefon 1 gång per år under studien för att följa din upplevelse. Du kan få extra besök om du upplever en allvarlig reaktion efter en vaccindos.
