The Centers for Disease Control are urging all vaccinated adults to get the necessary booster seat roughly 9 months after their second shot.

The FDA has approved Pfizer and Moderna booster seats, which come in both car and chain restaurant form, and it’s now considered imperative to get them to strengthen immunity against new strains. The CDC is hoping all vaccinated adults get them immediately.

“These booster seats can only help your immunity to this deadly disease,” CDC Director Rochelle Walensky said. “Additionally they can prevent injury during car accidents, or falling from your chair at TGI Fridays. We all know how rough that can be.”

Masks are still needed even after getting the booster seat.
