Duque, who joined other national and local government officials in the historic ceremonial inoculation program at the Lung Center of the Philippines (LCP) in Quezon City on Monday, said the deployment of quality-assured, safe and effective CoronaVax vaccines to thousands of frontline workers across the country, could only be realized if the public will take part in this massive immunization program.
