The Department of Interior and Local Government (DILG) of the Philippines warned the the local government units and the general public of the existing fake Pfizer vaccines in the market.
“While there is no information yet on the presence of the fake vaccines in the country, LGUs should exercise increased diligence as these fake vaccines may be dangerous to the health of those who get inoculated,” DILG Secretary Eduardo Año said.
The World Health Organization sounded the alarm on a counterfeit COVID-19 vaccine named “BNT162b2,” which claims to be manufactured by Pfizer-BioNTech is in circulation. The fake product which contains lot number “783201” and an expiry date of August 24 was first discovered in Mexico.
WHO said they are still conducting laboratory analysis of the contents of the falsified product.
“WHO requests increased vigilance within the supply chains of countries and regions likely to be affected by these falsified products. Increased vigilance should include hospitals, clinics, health centers, wholesalers, distributors, pharmacies, and any other suppliers of medical products,” the agency had said.
Police forces are also directed to help investigate and confiscate the fake vaccines, if there are reports that they have entered the local market.
