Vaccine

Type
Journal article
Scope
Afghanistan

Vaccines

Type
Journal article
Scope
Not classified

Why it matters nowThe authors frame the findings as relevant to vaccination policy, arguing that controlling for healthy-vaccinee bias is important when comparing vaccine effectiveness and that, during a period of high vaccine availability and COVID-19 mortality, Moderna was associated with lower COVID-19 mortality than Pfizer.
