E.1.1 | Medical condition(s) being investigated |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether meningococcal serogroup A specific SBA geometric mean titres (GMTs) are significantly higher at 7 days after immunisation with MenACWY than 7 days after immunisation with MenACWY PS. |
|
E.2.2 | Secondary objectives of the trial |
To determine whether meningococcal serogroup C, W-135 and Y specific SBA GMTs are significantly higher at 7 days after immunisation with MenACWY than 7 days after immunisation with MenACWY PS. To compare specific plasma cells, memory B cells and SBA GMTs at -7 days, and memory B cells and SBA GMTs at 28 days after a first and second dose of MenACWY conjugate vaccine. -7 days, and memory B cell and SBA levels at 28 days after the MenACWY conjugate vaccine given to participants with or without previous MenACWY PS immunisation. -at day 7, and memory B cell and SBA GMTs 28 days following a booster dose of MenACWY conjugate vaccine in adults previously vaccinated with MenACWY PS or MenACWY. To compare the memory B cell, plasma cell and SBA response to the serogroup A component of the polysaccharide ACWY vaccine to that of the other serogroups (C, W135 and Y) after MenACWY and MenACWY PS. To investigate the effect of genetic polymorphisms on immune response to the Men ACWY vaccine. |
