MANILA - Minority congressmen are set to file a resolution seeking an investigation into the government's dengue vaccination program, Senior Deputy Minority Leader Lito Atienza said Wednesday.

"May gumawa ng maling desisyon. Maraming buhay ang nanganganib...We have to have somebody accountable so the government can learn," Atienza told reporters.

The government last week suspended the vaccination program after French drugmaker Sanofi disclosed that Dengvaxia may cause "more cases of severe disease" if given to those who have not had the mosquito-borne illness before.

Sanofi said Dengvaxia would not cause anyone who was immunized to die and that potential cases of "severe dengue" would not be fatal.

Atienza said a legislative inquiry would be far from a political move, as individuals, no matter if they belong to the current or previous administrations, should be held accountable.

He said House committees may also be made liable if found that they had a hand in approve the use of Dengvaxia and if they failed to release a committee report on the vaccine.

The World Health Organization (WHO) Representative Office Philippines on Tuesday said it did not prescribe the use of Dengvaxia for national immunization and that it hoped to review safety data this month on Sanofi's dengue vaccine which the company said was approved in 19 countries and launched in 11. - with Miguel Dumaual, ABS-CBN News
