A vaccine works by making your body prepared to fight off infections if you come into contact with it.

Researchers at Crossroads Clinical are doing a study open to healthy volunteers aged 50 and up. In this study, a booster of the Moderna COVID-19 vaccine will be given with a pneumococcal vaccine. This study seeks to learn if these vaccines are helpful as preventative measures.

Crossroads Clinical Research

Medical research studies can be a great opportunity for people to receive medical services at no cost and to learn more about their medical condition. In most cases, volunteers in medical research studies are compensated for their time and travel commitments in the form of a stipend. At Crossroads Clinical Research Associates, they try to make volunteering a positive experience for every participant.

Please note:
Due to the COVID-19 pandemic, the researchers would like to assure the participants that ensuring their and the study staff’s safety is of utmost importance.
