Three-year-old Trax waved from a distance, but his hesitant steps turned to a run when he heard his grandmother’s voice ringing through the park.

“Come here! Oh my goodness, I’ve missed you so much.”

Jean Chvala had gotten her second COVID-19 vaccine two weeks before the video was shot in early March in western Pennsylvania. She lifted her grandson into her arms in a video clip that has gained national attention.

She hadn’t hugged Trax since October, Trax’s mom, Kelsey, told USA TODAY. For much of the year, Jean and her husband, Terry, have been “pretty isolated,” staying at home as much as possible to keep safe.

“She’s just so happy to see him again,” Kelsey Chvala said. “A piece of her just felt like it was missing.”
