"Currently there aren't a lot of hip-hop lyrics dedicated to scientific advancement."
Lyrics in the song address the common misconceptions about the virus, including how the vaccine was developed so fast and why young New Zealanders shouldn't hesitate about getting the jab.
"Reason it went quicker cause the money rolled in thicker, meaning trials could be bigger with more results to deliver," one lyric reads.
"I know what you're thinking, I'm young I'm healthy / The virus won't affect me, how can Pfizer help me," Randa says during the song.
The music video was released on YouTube and features a number of familiar faces, from leading scientists to politicians.
Making her debut as a featured rap artist, top microbiologist Dr Siouxsie Wiles laid down some lines for the cause.
"I'm not a huge hip-hop head but I was happy to contribute to this message," Wiles said.
But Rindelaub said he was impressed by her "fearless delivery on the mic".
Despite being a new area for academics, Rindelaub said it was great to see people like developmental paediatrician Dr Jin Russell and chief science adviser Dame Juliet Gerrard get involved.
"Seeing these science legends give it their all on camera just shows how strongly they feel about the importance of vaccines," he said.
Act leader David Seymour also makes a brief cameo, spitting some rhymes outside the Beehive.
MP for Auckland Central Chlöe Swarbrick also makes a short appearance.
The video is directed by Matt Cooke, with music production by Floyd Cribb.
