Explore an Investigational Vaccine Trial for Mono

Mono is no joke. Infectious mononucleosis (also known as mono) is easily transmissible and can make your regular activities difficult for days, weeks, or even months. People can spend up to two weeks in bed, which means missed appointments, missed work or school, and missing out on life in general. But what if mono wasn’t something we had to worry about or even think about?  

Mono is most often associated with infection caused by Epstein-Barr Virus (EBV).  Right now, the Eclipse Trial is underway at Moderna on an investigational vaccine that may protect against EBV and mono.

Consider this: 9 out of 10 people in the US get infected with mono by age 35, so finding a way to reduce mono infections in the world would be a major feat. You may be able to take part to help make an impact on the future of this disease.  

Participation in the Eclipse Trial is approximately 18 months. You will be compensated for your time. Eligible participants must be:

• 18 to 30 years of age

• Be in generally good health
