Flu Vaccines: What are the facts?

Is the annual flu vaccine sales pitch (evident not just in the U.S. but around the world) working? Given predictions of a 50% increase in the global influenza vaccine market by 2023 (from $5 billion to $7.5 billion), it would seem so. On the other hand, recent estimates of influenza vaccine coverage in U.S. adults show that Americans are growing more, rather than less, skeptical. In 2017-2018, influenza vaccine coverage fell for every adult age group (and all but one racial/ethnic group), reaching the lowest level in eight flu seasons. While influenza researchers may be “hesitant to discuss problems with the vaccine ‘because they’re afraid of being tainted with the antivaccine brush,’” the bottom line is flu shots are big business and vaccine injuries aren’t rare.
