Manila: Parents lined up from sunrise holding sleeping infants as the Philippines launched a campaign on Monday to vaccinate millions of children against polio, which has re-emerged nearly two decades after the nation’s last cases.
###
Years of falling vaccination rates, made worse by the botched rollout of a dengue vaccine, culminated in an outbreak of the preventable disease in September.
###
“This is for the welfare of my child,” Ruth Miranda told AFP after the vaccine was squirted into her child’s mouth at the Manila slum they call home.
###
Miranda’s child is among scores who are unprotected in the capital of about 13 million people, where vaccination rates of young children plunged from 77 percent in 2016 to a mere 24 percent in June.
###
The atmosphere at the event in Manila was festive – with ice cream vendors and music – but the stakes for the campaign are high.
###
Polio, which can cause paralysis and can be fatal in rare cases, has no cure and can only be prevented with several doses of oral and injectable vaccines.
###
Two cases were detected in September, the first polio infections in the Philippines since 2001, adding to the woes of a country already hit by deadly measles and dengue epidemic.
###
The risk of the disease spreading within the Philippines is high, according to World Health Organization, due to low immunisation coverage partly blamed to a dengue vaccine scandal.
###
The Philippines was the first nation to use Dengvaxia in a mass programme in 2016, but a botched rollout led to claims that children had died after being vaccinated.
###
A dramatic drop in vaccine confidence followed, with trust plunging from 93 percent in 2015 to 32 percent in 2018, according to a study led by the London School of Hygiene and Tropical Medicine.
###
The Philippines polio outbreak has been traced back to the weakened form of the virus used in vaccines, which is excreted by people for a time after they receive it.
###
According to the WHO, that form can mutate and spread in the surrounding community when immunisation rates get too low.
