The Philippine government is not taking ‘No’ for an answer.

The health minister is threatening to file a civil lawsuit against Sanofi after the company twice refused to issue a full refund for all dengue vaccine that was used during a recent immunization campaign. The government ended the program last month after learning that Dengvaxia could worsen — rather than prevent — future cases of the mosquito-borne virus in people who had not previously been infected.


“It is not the product that they promised it to be,” Enrique Domingo, the Department of Health undersecretary, said in a statement. “We believe they are really at fault here. And of course, if we find any further evidence, it might lead to a criminal case, because we believe there may have been some misrepresentation on the side of Sanofi.”
