An “urgent preliminary report of Yellow Card data” issued by the UK-based Evidence-Based Medicine Consultancy Ltd submitted to the Medicines and Healthcare Products Regulatory Agency (MHRA) states that “the MHRA now has more than enough evidence on the Yellow Card system to declare the COVID-19 vaccines unsafe for use in humans.”
Similar to the U.S. Vaccine Adverse Events Reporting System (VAERS), the MHRA describes the purpose of its Yellow Card system as providing “an early warning that the safety of a medicine or a medical device may require further investigation.”
