NCT06280157
The goal of this follow-up study is to investigate the persistence of the immune response induced by the GBS-NN/NN2 vaccine in women who have participated in study MVX0002, and/or in study MVX0003 with GBS-NN/NN2 vaccine and received 1, 2 or 3 doses of GBS-NN/NN2. The main question it aims to answer is to determine the persistence of the immune response induced by the GBS-NN/NN2 vaccine by measuring antibody concentrations. Participants who had received a primary course of GBS-NN/NN2 in Study MVX0002 and/or MVX0003 will be invited to return to have a single yearly blood sample of approximately 10 mL collected 2 to 5 years after the completion of the previous vaccination.
