Philippines bans Sanofi dengue vaccine as incidence doubles
Manila banned the Dengvaxia vaccine in February after the deaths of several dozen children who were among over 700,000 people immunised in 2016 and 2017
Manila — The Philippines stood firm on Tuesday on its ban on the world’s first dengue vaccine while declaring a nationwide epidemic from the mosquito-borne disease that it said has killed hundreds in 2019.
Dengue incidence shot up 98% from a year earlier to 146,062 cases from January 1 to July 20, causing 662 deaths, health secretary Francisco Duque told a news conference in which he announced a “national dengue epidemic”.
Manila banned the sale, import and distribution of the Dengvaxia vaccine in February following the deaths of several dozen children who were among more than 700,000 people given shots in 2016 and 2017 in a government immunisation campaign.
Duque said on Thursday that the government was studying an appeal to allow French pharmaceutical firm Sanofi to put the vaccine back in the Philippine market, but ruled out using the drug to combat the ongoing epidemic, which has hit young children hard.
“This vaccine does not squarely address the most vulnerable group which is those 5-9 years of age,” Duque said.
The vaccine, now licensed in 20 countries according to the World Health Organisation (WHO), is approved for use for those aged nine years and older.
Duque said the UN agency also advised Manila that the vaccine was “not recommended” as a response to an outbreak, and it was “not cost-effective” anyway, with one dose costing a 1,000 pesos (about $20).
Dengue, or haemorrhagic fever, is the world's most common mosquito-borne virus and infects an estimated 390-million people in more than 120 countries each year, killing more than 25,000 of them, according to the WHO.
The Philippines in 2016 became the first nation to use Dengvaxia in a mass immunisation programme. But controversy arose after Sanofi disclosed a year later that it could worsen symptoms for people not previously infected by the dengue virus.
The disclosure sparked a nationwide panic, with some parents alleging the vaccine killed their children.
The controversy also triggered a vaccine scare that the government said was a factor behind measles outbreaks that the UN Children's Fund said have killed more than 200 people in 2019.
On Tuesday, Duque called on other government agencies, schools, offices and communities to get out of their offices, homes and schools every afternoon to take part in efforts to “search and destroy mosquito breeding sites”.
