One of the biggest challenges faced by makers of COVID-19 vaccines has been attracting a diverse population of participants to clinical trials. To be approved, vaccines must be tested on different ethnic groups for differences in effectiveness, side effects and dosage. Johnson & Johnson turned to Dr. Kenneth Kim, who has conducted hundreds of clinical trials in the highly diverse Los Angeles area, to get it done. As time was of the essence, Dr. Kim relied on THO's healthcare expertise to quickly attract enough trial participants from an array of ethnic groups. The THO healthcare team created a lightning-fast program that placed live coverage in major broadcast outlets serving diverse audiences. Coverage by ABC7, KTLA, KNX Radio and Spanish-language Estrella-TV drew a fresh pool of candidates to Dr. Kim's lab allowing him to gather the necessary data to help the now-famous Johnson & Johnson single-dose vaccine gain emergency use authorization from the FDA.
