Doc Willie Ong, 58, is an internal medicine specialist, cardiologist, author and medical commentator who gained popularity primarily through social media where he offers medical and healthcare-related advice.

Ong also briefly served as a Department of Health consultant. He left ABS-CBN’s Salamat Doc in 2018 to run for the Senate, running a campaign backed by his substantial online presence and strong support from migrant Filipino workers. For a neophyte candidate, Ong placed a surprisingly high 18th place in the polls with 7.6 million votes.

He has been supportive of the COVID-19 vaccines’ efficacy, a contrast to his vocal opposition to the dengue vaccine, Dengvaxia. The involvement of high-profile figures like Ong in the propagation of unsubstantiated stories about the Dengvaxia controversy may have caused vaccine hesitancy during that period that stretches on until the height of the COVID-19 pandemic, according to critics. Ong maintains his stance that there is no conflict between his beliefs, arguing that Dengvaxia is different from the COVID-19 vaccines.

Manila Mayor Isko Moreno Domagoso chose Ong as running mate in the 2022 elections for his medical background and expertise. Ong is advocating for health system reform, including improved support for health infrastructure.
