The study is researching a new **pandemic flu vaccine** using *messenger ribonucleic acid (mRNA)* technology. mRNA is like a set of instructions for your body to make proteins to help fight viruses. This vaccine targets a specific flu strain called **H5**. The study will test different amounts of the vaccine to find the best dose and will compare it to a placebo (a shot with no medicine). It will involve 276 **healthy adults** and will last about *13 months* for each person.
Key Points:
- Participation lasts for about 13 months, with multiple visits needed.
- Participants must be healthy adults, 18 years or older, and women must not be pregnant or breastfeeding.
- Participants cannot have certain medical conditions or histories, like allergies to vaccine ingredients or recent vaccine participation.
By joining, participants help find the right vaccine dose for future studies. Make sure you meet the eligibility criteria before considering participation. This study offers a chance to contribute to important medical research, but there are some health requirements and time commitments involved.
