Philippines begins world’s first mass dengue vaccination
MANILA // The Philippines yesterday launched the first public immunisation programme for dengue fever. The scheme proposes to administer to a million schoolchildren the world’s first licensed vaccine against the mosquito-borne disease that the World Health Organisation estimates infects 390 million people a year.
Hundreds of Year 4 pupils at a public school in metropolitan Manila’s Marikina city were given the first of three shots of Dengvaxia. Some of the pupils received their vaccination shot under the glare of cameras during a festive ceremony at a gymnasium.
The Philippines had the highest incidence of dengue in the WHO’s Western Pacific region from 2013 to 2015, recording 200,415 cases last year, according to the department of health.
Health secretary Janette Garin called the launch “a historic milestone” in public health.
“We are the first country to introduce, adopt and implement the dengue vaccine through the public health system and under a public school setting,” she said.
The government is spending 3.5 billion pesos (Dh279 million) to administer the free vaccines, which it bought at a discounted cost of 3,000 pesos for three doses for each child. Free vaccine programmes ensure that “health should be for all, rich or poor”, Ms Garin said.
The health department said a study showed that the vaccination of nine-year-old children for five years starting this year ccould reduce dengue cases by 24.2 per cent in the Philippines. The three doses of vaccine are given six months apart.
Dengvaxia, developed by the French pharmaceutical company Sanofi Pasteur, obtained its first licence in Mexico in December last year for use in people aged 9 to 45.
Regulatory agencies in Brazil, the Philippines and El Salvador followed. But the vaccine is awaiting regulatory reviews in Europe and dozens of non-European countries, as well as prequalification by the WHO.
According to the New England Journal of Medicine, a study of children from 9 to 16 years old showed that the vaccine reduced the risk of contracting dengue by 65.6 per cent.
It also prevents dengue hospital admissions by 80 per cent, and severe dengue cases by 93 per cent.
But the effectiveness was lower for children younger than 9, as well as against the type of dengue caused by serotype 2 – one of the four strains of dengue fever.
