Why vaccination rates are falling in the U.S.

Key Points:

• A KFF survey reveals that most Americans do not firmly believe common vaccine myths but many fall into an uncertain middle ground, feeling confused and susceptible to conflicting messages about vaccine safety and effectiveness.
• Rising measles cases in the U.S. have reached a 35-year high with 2,566 confirmed cases this year, while childhood vaccination rates have declined slightly and nonmedical exemptions have reached record levels, increasing public health risks.
• Vaccine hesitancy is complex, influenced by factors such as fear of side effects, distrust of institutions, preference for natural immunity, and exposure to emotionally charged misinformation amplified by social media and political figures.
• Experts emphasize the importance of listening to vaccine-hesitant individuals and engaging in open, evidence-based conversations rather than dismissing concerns, noting that many people rely on social media for health information.
• The success of vaccines in reducing disease visibility has lowered perceived risk of illnesses like measles, making some parents underestimate the threat and overestimate vaccine risks, highlighting the need for updated communication about current risks.
