Vaccines against hepatitis B virus confer effective protection. Enzyme-linked immunosorbent assay was developed to test for specific antibodies in female genital tract secretions. Anti–hepatitis B IgG and IgA were detected in the cervicovaginal secretions of women after hepatitis B vaccination, indicating a potential genital tract role for neutralizing antibodies against sexually transmitted hepatitis B virus.
Specific hepatitis B antibodies were detected in the female genital tract of hepatitis B–vaccinated women and may be a component of protection against this virus.
