“No new or unexpected adverse events were detected” with use of the diphtheria–tetanus-acellular pertussis (DTaP) shot over 19 years of follow-up, concluded a team led by Dr. Pedro Moro, of the U.S. Centers for Disease Control and Prevention.
The shot protects against three potentially serious infectious diseases of childhood, including whooping cough (pertussis). In recent years, the “anti-vaxxer” movement — a small minority of parents — has raised concerns that routine childhood immunizations might carry long-term health risks for kids.
