SAN ANTONIO – As their only child, Yvonne Rodriguez said she made sure her parents Patricio and Sylvia Elizondo were vaccinated early on against COVID-19. After her mother passed away three months ago after a long illness, Rodriguez said she continued watching over her 76-year-old father who was diabetic and had heart problems. “We did all the right things,” Rodriguez said. She said he rarely left the house, was always masked up, and even wore gloves, so she doesn’t know how or where he caught COVID-19.
