Immunogenicity of simultaneous versus sequential administration of a 23-valent pneumococcal polysaccharide vaccine and a quadrivalent influenza vaccine in older individuals: A randomized, open-label, non-inferiority trial.
Summary
The immunogenicity of simultaneous administration of quadrivalent influenza vaccine and pneumococcal vaccine was unknown. The purpose of present study is to compare the immunogenicity of simultaneous administration of influenza vaccine and pneumococcal vaccine with that of separate administration.
