Fake COVID-19 vaccines have been found in black markets in Mexico and Poland, Pfizer confirmed to The Wall Street Journal.
"Pfizer has identified counterfeit versions of its COVID-19 vaccine in Mexico and Poland," the company said. "We are cognizant that in this type of environment – fueled by the ease and convenience of e-commerce and anonymity afforded by the internet – there will be an increase in the prevalence of fraud, counterfeit and other illicit activity as it relates to vaccines and treatments for COVID-19."
Six people were detained in Mexico in February for selling fake Pfizer doses using distilled water. One suspect in Poland was charged with fraud after an unspecified amount of Pfizer vials were found in his apartment. That fake vaccine, which was not administered to anyone, reportedly contained hyaluronic acid, which is used in skin care.
Pfizer said it is working with "governments, law enforcement, health care providers and others to combat this illegal trade."
