Olivia Rodrigo wants her fans to be happy and healthy and vaccinated against COVID-19.

The “good 4 u” songstress, who also stars in “High School Musical: The Musical: The Series” on Disney+, met with President Joe Biden and his chief medical advisor Dr. Anthony Fauci at the White House on Wednesday to participate in a social media campaign urging young people to get their Covid 19 vaccination shots.

The 18-year-old shared a selfie with the president on her Instagram and encouraged followers to get vaccinated in the caption.

Rodrigo relayed the same message in an Instagram Reels video, shared by Biden and the official White House Instagram account. Biden’s Instagram account also shared a series of photos of the president and the pop star trying on his signature Aviator sunglasses.

“Thanks for stopping by, Olivia, and for using your voice to urge young people to get vaccinated,” reads Biden’s caption. “If we all do our part and get the COVID-19 vaccine, we can defeat this virus once and for all. Let’s do this.
