Mississippi had the highest rate of adolescents ages 1317 who were not vaccinated against the human papillomavirus in 2023, according to a study published May 11 in JAMA Pediatrics.
Mississippi also had the highest rate of cervical cancer incidence between 2018 and 2022, and the highest mortality rate between 2019 and 2023, according to American Cancer Society data.
The HPV vaccine may prevent more than 90% of cancers associated with HPV, including cervical cancer, according to the CDC. A recent study found that cervical cancer incidence has decreased more in states where vaccination rates have increased since the HPV vaccine was introduced in 2006.
If vaccination and screening rates remain as they are currently, researchers project cervical cancer incidence could reach elimination status in high-income countries by 2048, though it would decrease by only 23% in low- and lower-middle-income countries.
Here are the rates of adolescents not vaccinated against HPV, cervical cancer incidence and cervical cancer mortality, by state:
