Vaccine row weakens war on diseases

Immunisation rates for some illnesses are down to 60% over Dengvaxi panic

Widespread fears over a controversial dengue vaccine that some blame for child deaths are wreaking havoc on the Philippines’ war on preventable diseases, with many parents refusing to get their children immunised, a senior health official said yesterday.

Immunisation rates for polio, chicken pox, tetanus and other diseases are significantly down from previous years since the government suspended the sale and distribution of the Dengvaxia vaccine in December, Health Undersecretary Enrique Domingo told reporters.

The government is also investigating Dengvaxia’s alleged role in the deaths of at least 14 children who were among the 830,000 who got the vaccine as part of the world’s first public dengue immunisation programme in 2016-2017.

“Our programmes are suffering... [Filipinos] are scared of all vaccines now,” Domingo said, adding that immunisation rates for some diseases are down to 60 per cent, significantly lower than in recent years and below the target of 85 per cent.

The Philippine government is concerned about the potential for epidemics because of lower immunisation rates, he said.

Dengue — a mosquitoborne disease — infects 400 million people each year and kills 9,000 globally, the health department said, citing World Health Organization data.

The Philippines has one of the highest dengue fatality rates in the world, with 732 deaths last year, it added.

Dengvaxia’s manufacturer Sanofi disclosed in December, two months after the vaccination campaign was completed, that it could worsen symptoms for people who had not previously been infected with the virus.

The disclosure sparked nationwide panic, with some parents alleging the vaccine caused the deaths of their children.
