Public health experts are debating how to help the 1 million children in the Philippines who received a new vaccine against dengue that could, in rare cases, sicken rather than protect them. The country launched a campaign in 2016 to vaccinate schoolchildren against the mosquito-borne virus, which can cause high fevers, muscle and joint pains, and rashes. One year later, the campaign was suddenly halted after the vaccine’s producer, Paris-based Sanofi Pasteur, announced it could, in rare cases, trigger severe, potentially fatal forms of dengue in children who became infected with the virus despite their vaccination.
Now, critics of the vaccine, named Dengvaxia, say researchers should try to identify those at increased risk of harm, which might save their lives. But Sanofi Pasteur has no plans to conduct a big, complex study, although it is following the fate of about 1% of the vaccinated children for 5 years.
