This team from the Department of Preventive Medicine at the State University of New York at Stony Brook used cross-sectional data from the National Health Interview Survey (NHIS) to examine the association between hepatitis B vaccination of newborn males and autism. They found that boys vaccinated at birth had a threefold higher risk of autism compared to boys never vaccinated or vaccinated after the first month of life. The autism risk was higher in non-white boys. The authors concluded “[o]ur findings do not suggest that the risks of autism outweigh the benefits of vaccination; however, future research into hepatitis B vaccination scheduling is warranted.”
