Randall Park is having a pretty good week. Not only did his Marvel character, FBI agent Jimmy Woo, make his WandaVision debut on Friday, but the actor just learned the day before that he’s been vaccinated against COVID-19 for the past four months. If you were wondering how Park could be vaccinated without knowing it until now, there’s a pretty cool explanation: he took part in a clinical trial back in September out of sheer boredom, and there was a 50/50 chance of him actually receiving the vaccine. While appearing on The Talk, Park explained how he was convinced to join the trial by fellow actor (and medical doctor) Ken Jeong, who let him know that the facility was specifically looking for Asian-American candidates.
