Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to generate data on key parameters associated with assessment of influenza vaccines in individuals 50-64 years of age

Primary Objective:

* To describe the immunogenicity of High-Dose Trivalent Inactivated Influenza Vaccine (TIV) compared to TIV.
* To describe the safety profile of High-Dose Trivalent Inactivated Influenza Vaccine, as assessed by solicited adverse reactions collected for 7 days post-vaccination, and unsolicited adverse events (including Serious Adverse Events and Adverse Events of Special Interests) collected between Visit 1 and Visit 2

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be randomized to receive one dose of either High-Dose Trivalent Inactivated Influenza Vaccine or Trivalent Inactivated Influenza Vaccine. They will be followed up for safety for one month post-vaccination.
