Revaccination against hepatitis B virus of non-responding and low-responding infants immunised at birth. A parallel evaluation of rubella and tetanus vaccine.

The aim of the present study was to identify the true extent of the non-responsiveness in infants born from HBsAg-negative mothers, vaccinated against Hepatitis B Virus (HBV) at birth. Sixty-four non- and low-responding infants, selected from an initial cohort of 2009, were given two additional doses of recombinant HBV vaccine between the tenth and the twelfth month of age. A parallel evaluation was conducted on the response to anti-rubella and anti-tetanus vaccine.
