A recent vaccination campaign in the Philippines has faced significant challenges due to the spread of misinformation on social media, undermining public confidence and contributing to vaccine hesitancy. The Department of Health reported that more than seven million Filipinos received measles-rubella vaccines this year, yet around 230,000 declined the jab. Concerns about side effects were cited in 66% of refusals, with misleading content attributed as a major factor driving fear and reluctance.
The controversy intensified after a three-year-old boy, Jenette Torres Odena’s son, fell ill shortly after receiving a vaccine. Despite doctors ruling out any connection between his condition and the measles-rubella vaccine, photos of the child circulated widely on Facebook accompanied by false claims that the vaccine had killed him. His image was used in anti-vaccine videos viewed hundreds of thousands of times, fueling public anxiety.
Experts point to a complex backdrop contributing to vaccine skepticism in the Philippines. The country has struggled to regain routine immunisation coverage following previous setbacks, including a polio resurgence in 2019 and recurring measles outbreaks, exacerbated by lingering distrust after a controversial dengue vaccine rollout a decade ago. Daniel Fritz Silvallana, a health communication researcher, emphasized that hesitancy in the Philippines stems not only from a lack of scientific knowledge but also from deeper issues related to trust, politics, and past experiences with public health services.
The social media dissemination of false information was notably amplified by content creators such as Maharani Sona Shiloh, who incorporated the boy’s photo into videos alleging harm caused by vaccination campaigns. Shiloh’s videos, which have garnered millions of views, claimed vaccines contain dangerous substances like “human placenta” and “formalin” and accused the World Health Organization of pursuing depopulation agendas. She connected her assertions to broader conspiracy theories involving global governance and resistance to certain government policies.
Shiloh rejected accusations of spreading misinformation, positioning herself as a human rights advocate and questioning societal limitations on challenging official narratives. Meanwhile, some parents exposed to such content have expressed hesitation or refusal to vaccinate their children, citing the information they encountered as influencing their decisions.
Vaccinologists and healthcare professionals have criticized these claims as unsubstantiated and fear-driven. Helen Petousis-Harris of the University of Auckland explained that misrepresentations of vaccine ingredients and the exaggeration of rare adverse effects contribute to unfounded public alarm. Frontline health workers like Wenna Mae Belen in Sorsogon province report increased difficulty in engaging with parents, some of whom respond with hostility or mistrust fueled by viral anti-vaccine messages.
While Facebook removed Shiloh’s primary page following public outcry, related pages remain active, continuing to disseminate misleading content. Health workers call for patience and open dialogue with hesitant parents, underscoring that restoring trust requires more than expert authority—it demands empathetic communication and understanding of the social context surrounding vaccine acceptance.
