"I'm gonna be his best friend!" Balvin said with a smile. "That's what I want to be, yeah."
Sunday's event means a lot to Balvin, who was diagnosed with COVID-19 last year. The 35-year-old performer previously revealed he had tested positive for the virus during his virtual Premios Juventud acceptance speech last August.
"I had COVID, I know how it feels. You know, I had it really bad. I never want to get it ever again," Balvin told ET on Sunday. "You guys in America are really blessed to have so many vaccines right now, but I come from Colombia and we've only got two percent of people vaccinated so it will take a lot of years."
"So I want to help the world and just help them and get vaccines," he added. "What's going on in India is really sad, it really hurt my feelings, and I'm here [to be of] service."
Balvin said that, because of the pandemic, he hasn't been able to see his extended family for some time, and added, "I just can't wait to see my whole family vaccinated and hug them and be relaxed, you know?"
As for any future performances, Balvin said he "definitely can't wait" to get back to touring and performing live across the world.
"Summer is back, the world needs it!" he shared. "I can't wait, you know? I can't wait just to spread love, spread good energy, good vibes, and I just hope everybody can get vaccinated."
ET also spoke with Balvin this past week, where he shared what scares his about becoming a father.
"It scares me the fact that it's another life," he told ET's Denny Directo while promoting his new documentary, The Boy From Medellín. "And sometimes, we know life is so challenging that sometimes you feel that you cannot put up with yourself and how [are] you going to help your kid be stronger, better than you?"
Balvin was just one of the stars to make an appearance at VAX LIVE, which was hosted by Selena Gomez. Prince Harry, who served on the Global Citizen campaign chair with his wife, Meghan Markle, took part in the event, along with President Joe Biden, First Lady Dr. Jill Biden and Vice President Kamala Harris.
