Objective: To analyse the results of a hepatitis B vaccination programme, in order to find the levels of acceptance of the programme and adherence to it, as well as the immunological response and the impact of age, gender and the index of corporal mass (ICM).
Design: This was a retrospective study.
Setting: Primary Care.
Patients and other participants: 2,055 Primary Care professionals considered at risk (43.3% of the Area total).
Measurements and main results: Out of the total number of professionals at risk, 1,294 (63%) agreed to have the serological markers. The prevalence of markers of the hepatitis B virus (HBV) was 16.07% (208), which increased with age (p < 0.0001). 87% had three doses (961/1,106). 863 (89.8%) of these went through the post-vaccination controls and levels of HB antibodies above 10 IU/ml were found in 790 (91.5%). The fourth dose produced favorable results (66.7%) in individuals with HB antibodies between 10 and 100 IU/ml and unfavorable ones (3.8%) where the HB antibodies were below 10 IU/ml.
Conclusions: The hepatitis B vaccination programme has not enjoyed total acceptance by Primary Care professionals, although a satisfactory level of adherence has been reached. Age is the variable linked most closely to the risk of a poor immunological response, though ICM and gender should not be ignored.
