A California nurse helping to fight COVID-19 says she feels a special link to her mother, who helped battle the 1918 flu pandemic. Sigrid Stokes is a 76-year-old nurse from Salinas, California. She told The Associated Press she has no plans to immediately retire from her job. She says she is too busy working to save lives during a deadly pandemic, just as her mother did more than a century ago. Her mother, Kristine Berg Mueller, helped treat people during the flu pandemic that spread around the world in 1918. Today, Stokes is giving vaccinations to health care workers battling COVID-19. Mueller was a 14-year-old student in her native Norway when the flu pandemic hit. That pandemic killed an estimated 50 million people, including about 675,000 in the United States, records from the Centers for Disease Control and Prevention show.
