In the United States, the year 2019 is notable for the second highest number of measles cases since its elimination. The antivaccine movement has grown from a fringe element during the early 2000's into its own version of a media empire comprising of at least 480 misinformation websites, actively promoted both on social media and e-commerce platforms. The antivaccine lobby has also launched political action committees (PACs) as well as non-profit organizations that lobby state legislatures to promote vaccine exemptions and raise money for political candidates who adopt antivaccine platforms. The antivaccine movement currently runs mostly unopposed due to the fragmented and often ineffective system of provaccine policies. 


We are forming the Lancet Commission on Vaccine Refusal, Acceptance, and Demand in the United States to:
1. Report on the current state of vaccine refusal, acceptance, and demand
2. Identify and predict future trends in vaccine refusal, acceptance, and demand and its impact on public health
3. Shape demand-side vaccine uptake interventions and solutions countering antivaccine information

Potential Impact

Vaccine hesitancy and refusal is a persistent and significant threat to the American public's health. This commission's focus on synthesizing evidence-based interventions to increase vaccine acceptance and to develop an actionable policy agenda will substantially inform efforts to ensure high vaccination rates. 


The commission is administratively housed at National School of Tropical Medicine at Baylor College of Medicine and the Yale Institute for Global Health.
