Episode notes
Herd Immunity Threshold Matters
- Measles needs about 95% vaccination coverage to stop spread in communities.
- South Carolina's drop below that threshold allowed localized spread to expand.
Historical Mistrust Shapes Vaccine Choices
- Immigrant communities from Slavic-speaking countries may carry mistrust of government vaccine programs.
- That historical distrust translates into hesitancy in the U.S. despite reassurances about safety.
Policy, Politics, And Platforms Drove Exemptions
- Multiple forces fueled rising religious and nonmedical exemptions, including COVID-era politics and social media misinformation.
- Easier online exemption forms also lowered the barrier to opt out of vaccination.
