The Philippines is prepared for the "worst case scenario" after warnings that a vaccine against dengue fever could cause symptoms of the disease to become more severe.

French pharmaceutical giant Sanofi Pasteur admitted on Wednesday that clinical data showed that Dengvaxia – the first authorized vaccine against dengue – could worsen the disease in people who had not previously been infected with the virus.

Those who had been vaccinated "are being followed by adverse effects," he said.

He added that the health department was reviewing the hospital records for acute cases of dengue.
