Association Between Vaccination for Human Papillomavirus (HPV) and Autonomic Dysfunction and Menstrual...

Area of Science:

• Public Health
• Vaccinology
• Epidemiology

Background:

• Limited research exists on the safety concerns associated with human papillomavirus (HPV) vaccination.
• Understanding potential adverse events following HPV vaccination is crucial for public health.

Purpose of the Study:

• To investigate the association between HPV vaccination and the occurrence of autonomic dysfunction.
• To examine the relationship between HPV vaccination and menstrual irregularities in girls and young women.

Main Methods:

• A self-controlled case series study utilized a 25% random sample of a large claims database (2016-2020).
• The study included commercially insured girls and young women receiving their first HPV vaccine dose.
• Incidence rate ratios (IRRs) were estimated comparing post-vaccination periods to pre-vaccination periods, with adjustments for age.

Main Results:

• HPV vaccination was associated with elevated risks for both autonomic dysfunction (IRR 1.23) and menstrual irregularities (IRR 1.30).
• Menstrual irregularities showed a significantly higher adjusted IRR in the younger age group (9-17 years) compared to the older group (18-26 years).
• Young women aged 18-26 years exhibited a heightened adjusted risk for autonomic dysfunction (IRR 1.40).

Conclusions:

• HPV vaccination is associated with increased risks of autonomic dysfunction and menstrual irregularities.
• The observed risks associated with HPV vaccination vary significantly by age group.
• Further research is required to identify additional risk factors and fully understand HPV vaccination safety.
