Summary
This study found a 77% hepatitis B immunization rate in infants by 18 months in primary care. Key barriers to complete hepatitis B vaccination included patient transfer and missed appointments.
Area of Science:
- Pediatrics
- Immunology
- Public Health
Background:
- Hepatitis B vaccination is crucial for preventing chronic infection.
- Primary care settings play a vital role in childhood immunization programs.
Purpose of the Study:
- To determine the hepatitis B immunization rate among newborns and infants.
- To identify factors contributing to incomplete hepatitis B immunization series.
Main Methods:
- An inception cohort study tracked newborns and infants in six primary care practices.
- Immunization status was assessed at 9 and 18 months of age.
- Reasons for incomplete immunization were recorded.
Main Results:
- Hepatitis B immunization rates reached 60% at 9 months and 77% by 18 months.
- Common reasons for incomplete immunization included patient transfer (7%), missed appointments (4%), and parental refusal (4%).
- By 18 months, 95% of infants received at least two doses of the hepatitis B vaccine.
Conclusions:
- A 77% hepatitis B immunization rate was achieved by 18 months in primary care.
- Barriers to complete hepatitis B vaccination include patient transfer, missed appointments, and parental refusal.
