Summary Hepatitis B virus ( HBV ) infection has been documented as a risk factor for non‐Hodgkin lymphoma ( NHL ). However, there are few large cohort studies, and there is no report about the impact of HBV vaccination. We conducted this study to evaluate these issues. We used the nationwide cohort of the Taiwan National Health Insurance Research Database for 1997–2013. We compared the incidence and the risk of developing NHL and CD 20 + aggressive lymphoma between HBV and non‐ HBV cohorts. The hazard ratios ( HR s) were computed using Cox proportional hazards models. We matched these two large cohorts to reconfirm the data. We also compared the incidence of NHL between cohorts born before and after the inception of universal HBV vaccination. We found that HBV infection increased the risk for developing NHL and CD 20 + aggressive lymphoma, with HR s of 4.14 and 5.52, with a higher incidence of 17.07 and 13.9 per 100 000 person‐years, respectively, compared to the non‐ HBV cohort. The incidence of NHL in the cohort born in the era before universal HBV vaccination was higher with 1.85 per 100 000 person‐years compared to 0.74 in the cohort born later aged younger than 20. Our study confirms that HBV confers a greater risk for developing NHL , especially CD 20 + aggressive lymphoma. The impact of HBV vaccination is protective against lymphoma development in the teenagers in an endemic area, but longer follow‐up is needed for older age.
