The world anxiously awaits a vaccine for COVID-19—a one-size-fits-all solution to stop the pandemic now sweeping the globe.

This medical model depends on marrying a deep understanding of each person with comprehensive knowledge of all treatment options that might work for that individual, including at the genetic, molecular or cellular level.
