Key Points Question What is the association of BCG vaccination during childhood with subsequent cancer development? Findings In this 60-year follow-up of a clinical trial of the BCG vaccine that included 2963 participants vaccinated at a median age of 8 years, those who received the BCG vaccine had a subsequent lung cancer rate of 18.2 cases per 100 000 person-years. Participants who received the placebo had a lung cancer rate of 45.4 cases per 100 000 person-years. Meaning The findings suggest that receiving BCG vaccination during early childhood is associated with reduced risk of subsequent lung cancer development.
