An unvaccinated Virginia couple in their 40s recently died of COVID-19, leaving behind four children — and the dad with one tragic regret before he succumbed. “He called me up and said, ‘Mom, I love you, and I wish that I’d got the shot,’” said Terry Mitchem, the mom of Kevin Mitchem, to Washington DC’s NBC 4. She and other relatives of Kevin and his late wife Misty are now urging those who have to be vaccinated to get immunized. “Please get it,” Kevin’s father, Don Mitchem, told the station through tears.
