Though he wasn’t in the best of health, Salvador Macias, 83, enjoyed going to a neighborhood community center for senior activities in Long Beach, a beachside city about 25 miles south of downtown Los Angeles. He lived in a modest, tidy house with his wife, Manuela, and their adult daughter, Julie.Salvador suffered from three chronic health conditions: diabetes, high cholesterol and high blood pressure, says his son, Joe Macias.In August 2020 – four months before health care workers received the first COVID-19 vaccine – the elder Macias became ill with the disease, suffering from fatigue and severe shortness of breath. After several days, Salvador died at home. Manuela, who doesn’t have the chronic health conditions her husband had, also contracted COVID-19. She was hospitalized for a week, but survived.
