Thus the company had arrived at a voluntarydecision on February 7, 2012 to withdraw its OPV from the WHO list of pre-qualified vaccines," Panacea Biotec said in a statement.The company withdrew the vaccine despite undertaking several measures regrading refurbishment of the facility and strengthening of QMS from September to December, 2011.`Pre-qualification` is a process under which drug companies have to fulfill certain WHO-stipulated conditions to become eligible to supply vaccines to UN procurement agenciesglobally. WHO said OPV produced by Panacea Biotec will no longer be supplied through United Nations (UN) agencies. The company, however, said it will continue to supply OPVs which were produced prior to the production halt in September 2011, as monitoring and testing of these lotsconfirm compliance with quality specifications.
