Willie Nelson is among the many Americans who’ve signed up to receive the COVID-19 vaccine.

During his drive-through vaccination this week, a masked Nelson posed for a series of pictures, offering the camera a thumbs-up as he received his dose of the vaccine. The Texas-based Family Hospital Systems shared the images on Facebook, encouraging everyone to sign up for their shots and stating that “getting your COVID vaccine is Willie cool!”

The "On the Road Again" singer shared the post to his own Facebook page, writing: "Get your shot! Take care of yourself and others. #slowthespreadofcovid19."

Nelson, who turns 88 in April, is among the first mainstream country stars to publicly receive the COVID-19 vaccine, though many of his fellow artists have battled the virus.

John Prine, Joe Diffie and Charley Pride all died of complications of COVID-19 in 2020. Country stars such as Tyler Hubbard, Lee Brice, Runaway June’s Jennifer Wayne and Natalie Stovall have spoken about their experiences contracting the disease.

According to the Centers for Disease Control and Prevention, at least 383,351 Americans have died from COVID-19 since the outbreak began.
