NEW DATA SNAPSHOT: More work is needed to promote cancer prevention vaccines in WI

New data from the Wisconsin Immunization Registry shows stalled progress on HPV and hepatitis B vaccine rates — emphasizing major opportunities for cancer prevention and outreach efforts.

Between 2019 and 2021, HPV vaccine rates for children in Wisconsin ages 11-12 showed no improvement, and hepatitis B vaccine rates saw large declines in a majority of Wisconsin counties.

The HPV vaccine protects against at least six types of cancer. The HPV vaccine is recommended for children ages 11-12 for optimal benefit. The hepatitis B vaccine protects against liver cancer. It is now recommended for all newborns, children and teens, and adults up to 59 years.

See how the 2019 and 2021 data compare:
*2 or 3 doses depending on age at series initiation (2 doses if age 9-14 at initial vaccination and 3 doses if age 15+ at initial vaccination per CDC recommendations)

*2 or 3 doses depending on age at series initiation (2 doses if age 9-14 at initial vaccination, and 3 doses if age 15+ at initial vaccination per CDC recommendations).

CDC recommendations consider 3 doses by 24 months of age as up-to-date. Additionally, universal hepatitis B vaccination of adults 19-59 is now recommended. We do not have data on adult hepatitis B vaccine rates at this point in time.

Other key findings include:
  • HPV vaccine initiation rates have improved slightly among children ages 13-17 (59.1% in 2019, to 63.5% in 2021). HPV completion rates among children ages 13-17 also show slight improvement (45.6% in 2019, to 50.4% in 2021).
  • The gap in vaccination rates between females and males ages 13-17 seems to be narrowing. Vaccine rates for males saw the greatest improvement (5.3 percentage point increase for males, compared to a 4.2 percentage point increase for females).
  • Several counties in Wisconsin saw small declines in HPV vaccine completion for 11- to 12-year-olds in 2021 compared to 2019.
  • Hepatitis B vaccine completion rates for 24-month-olds fell by one percent (85.3% in 2019 compared to 84.3% in 2021).
