Was the old pertussis vaccine safe?
The old pertussis vaccine had far more risks than the hepatitis B vaccine. The old pertussis vaccine was called the “whole-cell” vaccine and had a high rate of severe side effects. Persistent, inconsolable crying occurred in one of every 100 doses, fever greater than 105 degrees occurred in one of every 330 doses, and seizures with fever occurred in one of every 1,750 doses. Due to negative publicity about this vaccine, the use of pertussis vaccine decreased in many areas of the world. For example, the Japanese Ministry of Health decided to stop using the pertussis vaccine in 1975. In the three years before the vaccine was discontinued, there were 400 cases of pertussis and 10 deaths from pertussis in Japan. In the three years after the pertussis vaccine was discontinued, there were 13,000 cases of pertussis and 113 deaths! It should be noted that although the side effects of the pertussis vaccine were high, children didn’t die from pertussis vaccine, they died from pertussis infection
