Polio vaccine misinformation on social media: challenges, efforts, and recommendations

On April 22, 2019, false rumors regarding the side effects of the polio vaccine quickly spread across various social media platforms, including rapid spread of misinformation had a detrimental impact on Pakistan's efforts to eradicate polio. This essay sheds lights on two critical aspects related to polio vaccine misinformation on social media in Pakistan. First, it examines the current state of polio vaccine misinformation on social media and finds it a significant threat to public health, resulting in vaccine refusals, erosion of trust in public health institutions, distrust in science, and providing opportunities for anti-vaccination groups and individual advocates to target healthcare workers involved in polio eradication efforts nationwide. Second, it highlights the collaborative initiatives undertaken by relevant government institutions and social media companies, which have proven inadequate in effectively addressing the persistent dissemination of mis/disinformation, particularly on Facebook. Lastly, we suggest Pakistan should adopt a more inclusive approach of engaging all stakeholders, promote independent fact-checking initiatives, and increase health literacy among the target population about the risks and benefits associated with the polio vaccine.
