PURPOSE: This study evaluated infrequent adverse reactions to hepatitis B
vaccine by investigating the association of this vaccine with adverse health
outcomes for U.S. children less than six years of age. The evaluation of the
association between hepatitis B vaccine and chronic arthritis provides needed
data, relevant to the Institute of Medicine's Report that there are inadequate
data available to assess the causal relationship of hepatitis B vaccine to
arthritis risk. METHODS: The 1993 (n = 5505 children) and 1994 (n = 6515
children) National Health Interview Survey (NHIS) datasets were analyzed to
provide post-marketing surveillance data from probability samples of the U.S.
population. Incident cases of adverse events were determined from the temporal
association between the hepatitis B vaccination and the adverse events.
Logistic regression modeling was used to adjust for potential confounding.
RESULTS: Controlling for age, race, and gender simultaneously in the 1994 NHIS,
hepatitis B vaccine was found to be associated with prevalent arthritis [odds
ratio (OR) = 5.91, 95% confidence interval (CI) = 1.05-33.14], incident acute
ear infections (OR = 1.60, 95% CI = 1.00-2.58), and incident
pharyngitis/nasopharyngitis (OR = 1.41, 95% CI = 0.95-2.09). CONCLUSIONS:
Evidence from this study suggests that hepatitis B vaccine is positively
associated with adverse health outcomes in the general population of US
children.
