title: [Recombinant hepatitis B vaccine in health personnel. Immunogenicity of a rapid vaccination schedule].
abstract: The immunogenic effect of a recombinant hepatitis B vaccine, administered in a dosage of 20 micrograms intramuscularly in the deltoid muscle on the months 0, 1 and 2, was evaluated in 185 employers of a general hospital. The influence of sex, age, overweight and smoking habit on the antibody response induced by the vaccine was also assessed. The seroconversion rate 40-60 days after the third dose in the 160 health professionals who completed the vaccination schedule was 88% (83% in males and 90% in females). It was 97% in individuals less than 30 years of age, 89% in those between 30 and 50 years, and 69% in those over 50 years. It was 97% in non obese and 66% in obese individuals (p less than 0.0001). No differences in seroconversion rate were found between nonsmokers, moderate smokers and heavy smokers. Untoward reactions were minimal. The rate of vaccinated individuals developing anti-HBs titers higher than 10 mIU/ml was 68%. This rate was lower than that found in most studies after vaccination in the months 0, 1 and 6, the difference being probably due to the use of a rapid schedule with a short interval between the second and third doses. Nevertheless, this schedule facilitates the vaccination programs in health staff and reduces the failure rate due to poor compliance.
