Bogus COVID-19 vaccines – some selling for $1,000 a shot and some using an anti-wrinkle substance as an ingredient – were found in black markets around the world, Pfizer confirmed to The Wall Street Journal.

"Pfizer has identified counterfeit versions of its COVID-19 vaccine in Mexico and Poland," the company said in a statement. "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 during a February police raid at a clinic after about 80 people paid $1,000 for a fake Pfizer dose from vials with fraudulent labels kept in beer coolers.

The New York-based pharmaceutical giant ascertained the vaccine’s fraudulence with microscopic tools and special light.

There were no reports of physical harm from the people who were administered shots.

"People were injected with distilled water," a health secretary told the newspaper.

The Pfizer statement added that "no legitimate vaccine is sold online."

Pfizer said it's working with "governments, law enforcement, health care providers and others to combat this illegal trade."
