Family Guy has been running for 19 seasons and if even 1/10th of the viewers look like Peter Griffin, they are at high risk for a negative outcome from COVID-19, so what better way to protect your ratings than to make sure that all of your viewers are vaccinated.

In the new short/PSA, Stewie and Brian take a cue from Innerspace and shrink themselves down to fit inside Peter’s Bloodstream so they can show everyone how vaccines, and specifically MRNA vaccines really work to help protect you from COVID-19.

Watch the new #FamilyGuy Short! Stewie and Brian travel inside Peter’s body to explain how vaccines work. Have questions about the COVID-19 vaccines? Visit for the most accurate and timely facts, so we can all get back to the moments we love and miss most.
