简要总结

Comparative assessment of the tolerability, safety, and immunogenicity of the FLU-M® Tetra quadrivalent inactivated split influenza vaccine and the Ultrix® vaccine in volunteers aged 60 years and above.

详细描述

Evaluation of the tolerability, safety and immunogenicity of the inactivated split influenza vaccine FLU-M® Tetra compared to Ultrix® vaccine in volunteers aged 60 years and above.

Volunteers were screened and randomized in three groups: the Flu-M Tetra w/p (with preservative) group, the Flu-M Tetra w/o/p (without preservative) group and the Ultrix® group. All subjects were followed up for 28 days post randomization and vaccination.
