Vaccination against HPV: boosting coverage and tackling misinformation

Area of Science:

• Oncology
• Immunology
• Public Health

Background:

• Cervical cancer, primarily caused by human papillomavirus (HPV), is a significant global health concern, particularly affecting underserved populations.
• The advent of HPV vaccines and screening offers a pathway toward global cervical cancer elimination.
• High vaccination coverage is essential for controlling HPV infection and achieving elimination goals.

Purpose of the Study:

• To examine the challenges in achieving and sustaining high HPV vaccination coverage in established public health programs.
• To share insights from Italy and Denmark regarding vaccination coverage trends and influencing factors.
• To underscore the importance of continuous monitoring and rapid response to misinformation.

Main Methods:

• Analysis of HPV vaccination coverage data in girls in Italy and Denmark.
• Identification of factors impacting vaccination rates, including program implementation and public perception.
• Review of strategies employed to address declining coverage and misinformation.

Main Results:

• Despite successful program establishment, both Italy and Denmark faced difficulties in reaching the >80% HPV vaccination coverage target.
• In Italy, coverage decreased from 76% to 69% among 15-year-old girls, potentially due to healthcare worker overload.
• Denmark experienced a significant drop in coverage (80% to 37%) due to safety concerns, necessitating corrective actions.

Conclusions:

• Sustaining high HPV vaccination coverage requires proactive monitoring using digital registries and swift counteraction against vaccine misinformation.
• Programmatic challenges, such as immunization center workload, can impact coverage rates.
• Effective public health strategies must adapt to address evolving challenges in vaccine uptake and public confidence.
