Human papillomavirus vaccination rates and state mandates for tetanus-containing vaccines

[[[ Objective: ]]] We sought to examine nationally the association between school mandates for adolescent tetanus-containing vaccines (Td and/or Tdap) and adolescent female human papillomavirus (HPV) vaccination. [[[ Methods: ]]] Each state was categorized by whether a school mandate for adolescent Td and/or Tdap vaccines was enacted. Mean HPV vaccine series initiation levels among adolescent females were compared between each mandate category. [[[ Results: ]]] Mean HPV vaccine series initiation levels were significantly lower in states without Td/Tdap vaccine mandates than in those with mandates (42.9% vs. 47.3%; p=0.004). [[[ Conclusions: ]]] School mandates for adolescent Td/Tdap vaccination may have a carry-over effect on HPV vaccination.
