This research study is looking for volunteers to test an investigational vaccine for people aged 18 to 65 who are generally healthy. The study will help scientists learn more about how the vaccine works in the body.

Participants will be involved in the study for about 12 months. During this time, you will need to visit the study center approximately 8 times. These visits are important for researchers to check how your body responds to the vaccine. Each visit will include some tests and questionnaires.

• **Study Length**: Around 12 months with 8 visits.
• **Eligibility**: Must be aged 18-65 and generally healthy.
• **Purpose**: To understand how the investigational vaccine works.

If you are interested and meet the age and health criteria, you might consider participating. This study aims to gather important information that could contribute to vaccine research. Remember, participation is voluntary and you can choose to leave the study at any time.
