Objectives

Narrative objectives1

This is an observational study to determine whether the presence or absence of flail affects the immunogenicity of the vaccine in RSV vaccinees aged 60 years or older. clinical information, saliva samples, and blood samples will be collected at the time of RSV vaccination, 1 month after vaccination, and 3 months after vaccination. The IFN production capacity of lymphocytes, RSV neutralizing response, and anti-RSV antibody titer will be compared in the presence and absence of flail.

Assessment

Primary outcomes

Difference in neutralizing antibody titer 1 month or 3 months post-vaccination depending on the presence or absence of flail

Key secondary outcomes

(1) Difference in IFN production capacity in lymphocytes 1 month or 3 months after vaccination depending on the presence or absence of frailty
(2) Difference in cytokine production by lymphocytes 1 month or 3 months after vaccination in patients with or without flail
3) Difference in CD8+CD107a+ lymphocytes 1 month or 3 months after vaccination with or without flail
4) Difference in neutralizing antibody titer 1 month or 3 months after vaccination between frail and pre-frail
5) Difference in IFN production capacity in lymphocytes 1 month or 3 months after vaccination of frail and pre-frail
6) Difference in cytokine production capacity in lymphocytes 1 month or 3 months after vaccination between frail and pre-frail
7) Difference in CD8+CD107a+ lymphocytes 1 month or 3 months after vaccination in flail and pre-frail
8) Difference in neutralizing antibody titer before and after vaccination in the frail group
9) Difference in IFN production capacity of lymphocytes before and after vaccination in the frail group
10) Difference in cytokine production by lymphocytes before and after vaccination in the frail group
11) Difference in CD8+CD107a+ lymphocytes before and after vaccination in the frail group
