In preparation for the National Influenza Vaccination Week, the Centers for Disease Control and Prevention hosted a press conference Friday afternoon to raise awareness around the universal need for people to be protected against influenza. “It’s a week that we typically highlight the importance of the flu vaccine,” Howard Koh, assistant secretary for health at the Department of Health and Human Services, told reporters. During a typical season, he said, most influenza incidents begin picking up in December. “Flu activity is now increasing across the country, and the flu season is well underway,” Koh said. “If you’ve been thinking about getting vaccinated for influenza, now is a very good time to do so.”
