Estudo de segurança de uma vacina para ajudar a proteger contra a doença de Lyme em crianças saudáveis
UM ENSAIO DE FASE 3, RANDOMIZADO, CONTROLADO POR PLACEBO, OBSERVADOR-CEGADO PARA AVALIAR A SEGURANÇA DE UMA VACINA DA DOENÇA DE LYME BASEADA EM OspA 6-VALENTE (VLA15) EM CRIANÇAS SAUDÁVEIS DE 5 A 17 ANOS DE IDADE
Este estudo é para entender se a vacina do estudo (chamada VLA15) é segura em crianças saudáveis.
Procuramos crianças que:
- são saudáveis
- tem de 5 a 17 anos
- não foram diagnosticados com qualquer forma de doença de Lyme no passado
- não receberam nenhuma vacina para a doença de Lyme no passado
A doença de Lyme ocorre com mais frequência em crianças dessa idade. A vacina do estudo pode ser usada potencialmente para ajudar a prevenir a doença de Lyme. O objetivo deste estudo é obter mais informações sobre a segurança da vacina do estudo nesta faixa etária.
Os participantes estarão neste estudo por cerca de 2 anos. Durante esse tempo, eles receberão VLA15 ou placebo (solução salina estéril) por meio de um "tiro" no braço. Iremos comparar a experiência de crianças que receberam VLA15 com aquelas que receberam placebo. Os participantes não saberão se recebem VLA15 ou placebo.
Todos os participantes deste estudo irão:
- faça as injeções em uma clínica ou no consultório de um hospital
- receber um total de 4 tiros
- receba as 3 primeiras injeções dentro de 6 meses
- receber a última injeção cerca de 1 ano depois
- necessidade de vir ao local do estudo para 6 visitas planejadas; 4 delas são visitas de vacinação e 2 são visitas de acompanhamento. Entraremos em contato com você por telefone 1 vez por ano durante o estudo para monitorar sua experiência. Você pode ter visitas extras se tiver uma reação grave após uma dose de vacina.
