Sir Mix-a-Lot once topped the local PSA charts with his City Light-produced “Reduce Your Bills and Cut Your Chills.” Three decades later he’s back at it again with his new Public Health – Seattle & King County-produced single “Baby Got Vax.”

The track and music video isn’t due out until later this month, but lyrics leaked earlier today are sure to be a hit with hardcore herd immunity fans.

“I’m all about the underground music scene, not the underground coffin scene,” Sir Mix said in a statement about the collaboration featuring DJ Jazzy Dow Constantine. “If your posse doesn’t have its measles, polio and whooping cough shots, jump on it.”

Those leaked lyrics? We pulled up quick to retrieve ’em:

Oh my god, Becky, look at this blog

It’s so good

She’s even one of those doctors girlfriends

Cuz, ya know, who understands those doctors anyways

They push vaccines because they’re a drug company prostitute

I mean, her blog, is just so big

I can’t believe this information is around and like out there

Vaccine, gross, look

It’s just so bad

I like vaccines and I cannot lie

And these new-age mothers can’t deny

That when the doc walks in with a medical case

And puts measles in its place

You look dumb

Mommy blogs ain’t enough

When these diseases got you cuffed

Deep in vaccines, I’m caring

You on Facebook, please stop sharing

Oh baby, I wanna get with you

And immunize you

My homeboys are simplistic

But those vaccine shots won’t make (your kid autistic)

Ooh, anti-vaxxer

You say you did research with your friends

Well, excuse me, excuse me

But you sound like the mom from Snoopy

Science advancin’

To hell with the chancin’

So get, set

And about Rubella never have to fret

I’m tired of magazines

Saying anti-vaxx is the thing

Take the average mom and ask her that

She gonna get that vax

So mothers (yeah) fathers (yeah)

Should your baby get vaccines (Hell Yeah)

Tell’em to hug it (hug it), kiss it (kiss it) and love that healthy baby

Baby got vax
