Proportional reporting ratio, or PRR, is a fraudulent measure of vaccine harm, designed by the Centers for Disease Control and Prevention expressly for the new COVID-19 vaccines to disguise the devastation the vaccines are causing.

Reporting only PRR and not the actual count provided a convenient cover for “business as usual.”
