Assessment of QBKPN Site-Specific Immunomodulator Efficacy in Improving Innate Immune Function & Reducing Respiratory Tract Infection Morbidity in Older Adults

This study is designed to test whether QBKPN SSI can improve immune function in older adults, including how well it can protect against respiratory and other infections, whether it improves the body\'s response to COVID-19 vaccines and what effect it has on maintaining or improving quality of life, activity level and health status. QBKPN is a new medication in a class known as Site-Specific Immunomodulators (SSI). SSIs are designed to train and/or improve innate immune function to reduce the risk of infections, improve immune response to cancer, and slow the progression of chronic inflammatory diseases. It is believed that QBKPN SSI can work with the immune system to help protect against respiratory and other infections.
