With over 20 COVID-19 vaccine candidates in development, experts warn that failing to achieve 70% population uptake due to widespread hesitancy could necessitate indefinite social restrictions. This crisis of trust is driven by political polarization, the legacy of the retracted Andrew Wakefield study, and algorithmic amplification of misinformation on social media platforms that have disproportionately spread falsehoods from figures like President Trump. In response, health organizations and tech-savvy clinics are launching counter-misinformation campaigns to protect herd immunity goals against hostile narratives that link political populism with declining public confidence.
