Negros Occidental Provincial Health Officer Ernel Tumimbang yesterday urged those who may have been administered the Dengvaxia, a dengue vaccine recalled by the national government, to inform his office so their situation can be monitored.
He said a drug store chain with branches in Bacolod malls had sold the vaccine and some individuals may have used it.
The Food and Drug Administration had suspended the sale, distribution and marketing of Dengvaxia in the Philippines, after its French drug maker,Sanofi Pasteur, released findings that the vaccine could worsen symptoms in people who hadnot previously been infected by dengue.
Sanofi said it had found that the vaccine was beneficial in preventing dengue fever only in people who had been infected by the dengue virus in the past.
Negros Occidental and Bacolod City were not among the areas covered by the DOH anti-dengue vaccination program, he said.
However, private individuals may have purchased the vaccine from a drug store with branches at Bacolod malls, Tumimbang said.
The vaccine could have been purchased mostly by the well-to-do as it costs PHP 4,000 each and has to be administered in three doses, Tumimbang said.
Only avery small portion of the population is believed to have purchased the Dengvaxia, he added.*CPG
